Creating layout on a rolled material

The nesting job procedure that follows takes you through the steps you need to take to create a layout by nesting the parts of a structure on a rolled material. In nesting on a rolled material, the material is fed not in sheets but in rolls. When using rolled material, EngView places the nested parts at the beginning of the roll (in its left side), which leaves unused material on the right. As a result, after a layout has been sent to production, you can use this leftover material for future jobs. EngView takes account of the leftover material and stores it in materials store.

Creating a rolled material

EngView treats as a roll any material whose length is at least five times greater than its height.

The procedure that follows starts from the the assembled state of a structure, in its respective drawing.

Defining the material

Start by defining a rolled material. You do this in the program's sheets catalog: On the Format menu, click Sheets.

The Edit Sheet dialog box appears.

In Width, set how long the roll will be; in Height, set how high it will be.

An example

Let us take a look at an example.

There are eight 1ups in the project. The first five use the ULTR500 material; the rest use the ULTR700 material.

This means there need to be two defined rolled materials.

Also, it is well-advised to input this information into the Materials Store Catalog. For the ULTR500 material, we set the Roll ULTR500 rolls; for the ULTR700 material we set Roll ULTR700 rolls.

The nesting job

Run the Display Nesting wizard.

The Multi-Part Nesting Wizard opens at the Parameters step.

Notice that there is information about the rolls that will be used for both nesting groups. This information comes automatically from the Materials Store Catalog.

Click Material and Tool Optimization . A dialog box appears, where you set up EngView to calculate nesting jobs on a rolled material.

The Cost Parameters dialog box appears.

In Material type, select Roll (pictured above).
In Min reusable roll length, type the minimum length for EngView to consider when saving the leftover material in the Materials Store Catalog. For details about how leftover material is stored and reused, see the notes for Remnant Sheet and Update material store quantities at the last step of the procedure.
(Optional) In Recommended chunk size, type how long you want chunks to be.

What is a chunk? A chunk is a subsection of the zone of the roll that EngView has populated with parts. After EngView has nested the parts onto a roll, you can choose to divide the populated section into multiple chunks, and cut each of them separately. Using chunks lets you evaluate the nesting on a particular subsection, and try a better nesting for the ones that carry unacceptable amounts of waste. EngView displays chunks as separate layout drawings, which you see in the wizard page. There you decide which chunk to cut and for which to try a better nesting configuration.

Close the dialog box to return to the Parameters step.

Notice that the label has changed to alert you that you are nesting on rolled material:

Proceed with the Parameters page.

NOTE: In the context of roll nesting, consider the word "sheet" to mean "roll".

The page is divided into three sections:

Progress bar. It is the sequence of technological steps that make up a nesting job.
The tabular section on the left, in which you group the parts for nesting (the upper pane) and select the sheets the job will work with (the lower pane). If you have set up the material store, its latest state is loaded here.
Graphical section on the right, displaying the selected part.

The table that follows guides you through the Parameters step.

The progress bar	The progress bar, in the uppermost section, follows the course of the nesting job. It covers a series steps whose number depends on the type of the material used in the 3D model and the grouping of the parts for the actual nesting. The first and last steps — Parameters and Results — are permanent, while the number of the intermediate steps depends on how many materials are used and how many nesting group are defined (see below). The name of an intermediate step is a compound generated automatically from the name of the used material and that of the nesting group. In the example above, ICB Board White 16, Nesting Group 1. Scroll below in the table to learn how to use nesting groups.

Quantity of displays to produce	This box has no role in the nesting on rolled materials.

1up Nesting Groups	Here you tell EngView how to nest the parts. When you select a part, it appears in the preview area on the right. If you have defined nesting groups in the materials store, based on a particular material, these are loaded automatically. IMPORTANT: If you make changes to the nesting groups that you want to use in the future, EngView updates them for you in the materials store. Learn how to define a nesting group.
Cost Parameters	Opens a dialog box in which you set the method of how to calculate an estimate for the cost of the production.
Name	The column displays three nesting job components: The name of the used material. Material names are added automatically by EngView . This name takes part in the EngView -generated name of the nesting job's intermediate steps. You cannot edit the name here. The nesting groups defined for the job. Each material used in the project defined its own set of nesting groups. There is always a default group, Nesting Group 1, whose name you cannot modify and cannot delete. You can tell EngView to always nest certain parts together. In this case, you need to group the parts into a separate group. To create a group: Select the name of the material. Click the Plus button above.A row appears for the new nesting group. Edit its name as you need it. From Nesting Group 1, drag into the new group the parts that you want to group individually in the new group. Repeat Steps 1–4 for each new group you choose to create. The indvidual parts that will take part in the nesting job. By default, when you begin, you see all available parts in Nesting Group 1. If you choose to have some parts always nested together, create additional nesting groups. (See the preceding note.) If you do not want to use a part in the nesting job, leave its check box empty. Article indicates the name of the article applied onto the part.
Rotation	Type an angle that EngView will use to rotate the part while populating the sheet. To specify a value for all the parts, set it across the name of the nesting group. To set an individual angle value for a part, set it across the part's name.
Spacing	A gap between the 1ups. To specify a global value, type it across the name of the nesting group. To set an individual spacing for part, type its value across the name of the part.
Delivery Quantity	Specify how many pieces of this part you want produced.
Overproduction	Not applicable for roll nesting.
Allowance	Not applicable for roll nesting.

Sheets	The rolls that will be used in the nesting job. NOTE: To add a roll, click any row in the table, and then click the Plus button; then, from the list that appears, select the roll. To delete a roll, click it, and then click the Remove button.
The rolls List	A list of the rolls selected for production. For each material, you see two default groups: All Sheets and Nesting Group 1. For each new nesting group you create, a new rolls group appears here. If you are working with multiple nesting groups, here you can add rolls to each group. To add a roll: Select a group's name. Click the Plus button. From the list that appears, select the roll that you want to work with. Repeat Steps 1–3 for each roll you want to add. Notice that each roll you add automatically goes to both its own nesting group and the All Sheets group.
Flute/Grain direction	Sets whether the roll will take into account the grain or flute of the material. The options are: fdX. Arranges the parts according to the horizontal flute/grain of the roll. fdY. Arranges the parts according to the horizontal flute/grain of the roll. fdAny. Ignores the flute/grain direction.

Count	Sets how many rolls you have on hand. The default value is Infinite — if this roll is registered in the Materials Store Catalog, it the count will come from there. This means unlimited number of rolls. Overwrite it with a number that works for you.
Width	Set how wide (long) your roll is.
Height	Set how high (wide) your roll is.
Left, Right, Top, Bottom	The values for the roll's left, right, upper and lower margins

The Preview Pane	A preview of the part selected in the Name column

Cost Parameters

Opens a dialog box in which you set the method of how to calculate an estimate for the cost of the production.

Name

The column displays three nesting job components:

The name of the used material. Material names are added automatically by EngView . This name takes part in the EngView -generated name of the nesting job's intermediate steps. You cannot edit the name here.
The nesting groups defined for the job. Each material used in the project defined its own set of nesting groups. There is always a default group, Nesting Group 1, whose name you cannot modify and cannot delete. You can tell EngView to always nest certain parts together. In this case, you need to group the parts into a separate group. To create a group:
1. Select the name of the material.
2. Click the Plus button above.A row appears for the new nesting group.
3. Edit its name as you need it.
4. From Nesting Group 1, drag into the new group the parts that you want to group individually in the new group.
5. Repeat Steps 1–4 for each new group you choose to create.
The indvidual parts that will take part in the nesting job. By default, when you begin, you see all available parts in Nesting Group 1. If you choose to have some parts always nested together, create additional nesting groups. (See the preceding note.) If you do not want to use a part in the nesting job, leave its check box empty. Article indicates the name of the article applied onto the part.

Rotation

Type an angle that EngView will use to rotate the part while populating the sheet. To specify a value for all the parts, set it across the name of the nesting group. To set an individual angle value for a part, set it across the part's name.

Spacing

A gap between the 1ups. To specify a global value, type it across the name of the nesting group. To set an individual spacing for part, type its value across the name of the part.

Delivery Quantity

Specify how many pieces of this part you want produced.

Overproduction

Not applicable for roll nesting.

Allowance

Not applicable for roll nesting.

Sheets

The rolls List

A list of the rolls selected for production. For each material, you see two default groups: All Sheets and Nesting Group 1. For each new nesting group you create, a new rolls group appears here. If you are working with multiple nesting groups, here you can add rolls to each group. To add a roll:

Select a group's name.
Click the Plus button.
From the list that appears, select the roll that you want to work with.
Repeat Steps 1–3 for each roll you want to add. Notice that each roll you add automatically goes to both its own nesting group and the All Sheets group.

Sets whether the roll will take into account the grain or flute of the material. The options are:

fdX. Arranges the parts according to the horizontal flute/grain of the roll.
fdY. Arranges the parts according to the horizontal flute/grain of the roll.
fdAny. Ignores the flute/grain direction.

Count

Sets how many rolls you have on hand. The default value is Infinite — if this roll is registered in the Materials Store Catalog, it the count will come from there. This means unlimited number of rolls. Overwrite it with a number that works for you.

Click Next to continue.

NOTE: Before proceeding, EngView checks the size of the chosen sheets. If the width is at least five time greater than the height, EngView treats this materials as a roll. In this case, if the Cost Model setting is other than Rolled, a warning appears:

NOTE: Or the reverse: If the size of the chosen sheet does not meet the roll condition but the Cost Model setting says Rolled, a warning appears:

An intermediate step appears. The wizard displays as many intermediate steps as there are materials and nesting groups set up for the nesting job.

Roll nesting on materials ULTR500 and ULTR700 for nesting group Nesting Group1. Тwo layouts are needed.

NOTE ON STEP NAMES: The name of an intermediate step is a compound from the name of the used material and that of the nesting group. This means that if you work with multiple materials, you will have as many individual pages as materials, and if you work with multiple nesting groups, you will have as many pages as groups. In other words, if you work with:

One material and one nesting group, the wizard will display one intermediate step.
Two materials and two nesting groups, the wizard will display four intermediate steps.

Roll nesting on material ULTR700 for nesting group Nesting Group1. One layout is needed.

The page is divided into three sections: a three-pane tabular section in the upper half and a preview area in the lower half.

Left-hand tabular pane lists the entire nesting solution.
The middle pane lists the same information as in the left-hand one, but shown by chunks, not by material. You see information for each chunk you have selected in the left-handed pane. You can see how many parts are nested on which individual roll or chunk, as well as the waste and cost of the roll/chunk.
The right-hand pane lists the 1ups (parts) and how many of them will be produced.
The preview pane in the lower half visualizes the nesting solution.

The Left-Hand Pane
Layout Variants	The names of the sheets that EngView will use for the nesting job.
Layout Variants	How many dies nestings the job requires.
Total Sheet Count	The total number of sheets EngView has computed for the nesting job. Note that if you see a red text and an alert tooltip here, this means that in Count (in the Parameters step) you have entered a number that is smaller than the one EngView has computed. This alert will not stop the nesting job, but if you want to be correct, it is best to go back to the Parameters step and modify the value in Count.
Waste %	The overall waste in relation to the total area of the sheet
Model Cost Estimate	The relative cost for the variant

The Middle Pane	This pane lists the information in the left-hand one but broken down to chunks, not displayed by material. You see information for each chunk you have selected in the left-handed pane. You can see how many parts are nested on which individual roll or chunk, as well as the waste and cost of the roll/chunk.

The Right-Hand Pane	The pane lists the parts of the nesting group. Selecting a part here highlights it in the visualization pane below.
1up	The name of the part. When you select a part, it is highlighted in the preview pane in all the sheets it appears.
Rotation	The angle of rotation that EngView has applied for the part when arrayed in the sheet
Delivery Quantity	How many pieces of this part you want produced. If colored results appear, see what they mean*.
Produced	The number of parts the nesting job will actually produce. NOTE: For roll nesting, the delivered and the produced quantities are equal. If colored results appear, see what they mean*.
Excess	In the context of roll nesting, excess is zero unless there are sufficient number of rolls o roll remnants. When the set production run cannot fit in the available rolls, this column lists the number of parts that cannot be produced — that is, a negative number appears. If colored results appear, see what they mean*.
Per Sheet	Indicates how many pieces of the part there are in each sheet in which the part appears. Examples: sh1:8 means Sheet 1 contains eight pieces of the part. sh1:4, sh2:4 means Sheet 1 contains four pieces of the part and Sheet 2 contains four pieces of the part. When you select the row, EngView highlights the part in the preview pane in all the sheets it appears. If colored results appear, see what they mean*.
*Colored results	Depending on the amounts you have set for a nesting job, in the right-hand pane you may see colored results in the columns Delivery Quantity, Produced, Excess and Per Sheet. The colors means as follows: Blue. The amounts produced are greater than what you have set. That means you will have surplus output. Red. The amounts produced are smaller than what you have set. This means you will have smaller output than what you need.

The Preview Pane	A preview of the nesting that EngView has computed. Notice that the entire nested group is pushed to the left side of the roll (its beginning), with the rest of the roll being blank. After the variant goes to production, the leftover portion will be stored for future use under the name you have chosen in the Remnant Sheet column in the tabular area (in the next step).

The Left-Hand Pane

Layout Variants

The names of the sheets that EngView will use for the nesting job.

Layout Variants

How many dies nestings the job requires.

Total Sheet Count

The total number of sheets EngView has computed for the nesting job. Note that if you see a red text and an alert tooltip here, this means that in Count (in the Parameters step) you have entered a number that is smaller than the one EngView has computed. This alert will not stop the nesting job, but if you want to be correct, it is best to go back to the Parameters step and modify the value in Count.

Waste %

The overall waste in relation to the total area of the sheet

Model Cost Estimate

The relative cost for the variant

The Middle Pane

This pane lists the information in the left-hand one but broken down to chunks, not displayed by material. You see information for each chunk you have selected in the left-handed pane. You can see how many parts are nested on which individual roll or chunk, as well as the waste and cost of the roll/chunk.

The Right-Hand Pane

The pane lists the parts of the nesting group. Selecting a part here highlights it in the visualization pane below.

1up

The name of the part. When you select a part, it is highlighted in the preview pane in all the sheets it appears.

Rotation

The angle of rotation that EngView has applied for the part when arrayed in the sheet

Delivery Quantity

How many pieces of this part you want produced. If colored results appear, see what they mean*.

Produced

The number of parts the nesting job will actually produce. NOTE: For roll nesting, the delivered and the produced quantities are equal. If colored results appear, see what they mean*.

Excess

In the context of roll nesting, excess is zero unless there are sufficient number of rolls o roll remnants. When the set production run cannot fit in the available rolls, this column lists the number of parts that cannot be produced — that is, a negative number appears. If colored results appear, see what they mean*.

Per Sheet

Indicates how many pieces of the part there are in each sheet in which the part appears. Examples:

sh1:8 means Sheet 1 contains eight pieces of the part.
sh1:4, sh2:4 means Sheet 1 contains four pieces of the part and Sheet 2 contains four pieces of the part.

When you select the row, EngView highlights the part in the preview pane in all the sheets it appears. If colored results appear, see what they mean*.

*Colored results

Depending on the amounts you have set for a nesting job, in the right-hand pane you may see colored results in the columns Delivery Quantity, Produced, Excess and Per Sheet. The colors means as follows:

Blue. The amounts produced are greater than what you have set. That means you will have surplus output.
Red. The amounts produced are smaller than what you have set. This means you will have smaller output than what you need.

The Preview Pane

A preview of the nesting that EngView has computed. Notice that the entire nested group is pushed to the left side of the roll (its beginning), with the rest of the roll being blank. After the variant goes to production, the leftover portion will be stored for future use under the name you have chosen in the Remnant Sheet column in the tabular area (in the next step).

Review the nesting job, and then click Next. If you want to modify the job, click Back and do the necessary editing in the Parameters step.

The Results step of the wizard appears, which is an overview of the selected nesting.

Two rolls are needed for cutting of parts in the ULTR500 material in Nesting Group1. That is why there are two layouts. The first will use 9910 mm from the roll; the second 610 mm.

One roll is needed for cutting of parts in the ULTR700 material in Nesting Group 1. That is why there is one layout, which will use 4187 mm of the roll.

To update the Materials Store Catalog with the remnants of the used rolls, select the Update materials store quantities check box.

Additional information appears about the remnants of the used rolls (pictured above). It is this information that will be entered into the Materials Store Catalog.

Material	Displays: The material used for the nesting group. A list of the rolls used for the nesting job.
Quantity	Displays how many rolls are needed for producing the production run.
Waste %	Displays the share of the waste for the sheet.
Layout Name	(editable) A name that EngView generates from the name of the material, the name of the sheet/roll, and the number of sheets/rolls that the job needs. Example: The name B FluteBobst SP 162 X 100 reads: B Flute (material), Bobst 162 SP (sheet name), 100 (number of required sheets/rolls). After the layout is generated, this name appears as the name of the layout drawing. You can edit it here if you want to have memorable names.
Remnant Sheet	(editable) Information about what is left over from the used rolls. If the leftover is at least twice as long as it is reported as a remnant. Otherwise, it is treated as a piece. This is the name that EngView will use to store the remaining part of the roll in the materials store. What you type here will update the store. It will appear the next time you begin a nesting job. It's up to you to rename the default text into a memorable name.
Update material store quantities	Select the check box to start updating the materials store. When you select the check box, an additional column — Remnant Sheet — appears in the table above. (See the previous row for details.)

To apply the selected layout variant, click Finish. This also updates the Materials Store Catalog.
