Constructing grids
This page explains how to create a drafting
grid. Learn more about grid and
how you can use it to make your drafting easier.
To add a drafting grid to an object (line or arc)
- Point to the object to which you want to add a grid, right-click,
and then click Construct Grid.
Constructing grid on a line
Constructing grid on an arc
The Grid Properties dialog box appears.
The Grid Properties dialog box is where you define how many parallel
and perpendicular guides you want your grid to have.
I. Adding perpendicular guides
- To draw guides perpendicular to the object, in the Perpendicular
Guides section, click Add perpendicular guide
,
and then click how many lines you want your grid to have.
NOTE: The outer guides are counted. This
means that, if you want the grid to divide the object into three sections,
you need to select 4 Guides.
When you click an option, records for the guides
appear in the list.
Position |
Sets the guides' positions along the object (line or arc).
In each record, click in Expression to see the options
that you can use to position the respective guide.
- Distance from beg: How far from the object's beginning you want the guide.
- Distance from end: How far from the object's end you want the guide.
- Ratio from beg: Positions the guide according to a ratio along the length starting from the beginning.
Type 1/2 if you want the guide at the object's halfpoint; type 1/3 if you want it at a third from the beginning, and so on.
- Ratio from end: Positions the guide according to a ratio along the length starting from the end.
Type 1/2 if you want the guide at the object's halfpoint; type 1/3 if you want it at a first third from the end, and so on.
|
Expression |
The expression that sets the position of the guide relative
to what you have chosen in Position Type a value for
how far you want to position the guide. |
Value |
The value for the position to which the expression evaluates. |
- (Optional) In Expression, edit the distances of the
individual guides if you need them positioned differently. (Consult
the table in Step 1.)
NOTE: You can type a number, a parameter
(it has to exist in the project already), or formulas.
- (Optional) To draw individual perpendicular guides, click Add
perpendicular guide
. As you add a new
guide, its record appears in the list. Edit each new guide as
you need it.

II. Adding parallel guides
- To add parallel guides to the object, in the Parallel Guides
section, click Add parallel guides
.
The Add Parallel Guides dialog box appears.
- Type how many guides you need on either side of the object.
Consult the following table:
For a line object |
For an arc object |
Upper guides count |
How many guides you want above the line. |
Outer guides count |
How many guides you want outside the arc. |
Lower guides count |
How many guides you want below the line. |
Inner guides count |
How many guides you want inside the arc. |
Distance |
How far apart you want the guides. |
- Type values for the parallel guides.
Records appear for the guides in the list.
Note that the upper/inner guides have positive values and the lower/outer
guides have negative values.
- (Optional) In Expression, edit the distances of the
individual guides if you need them positioned differently. (Consult
the table in Step 2.)
NOTE: You can type a number, a parameter
(it has to exist in the project already), or formulas.
- (Optional) To draw individual parallel guides, click Add
parallel guide
. As you add a new guide,
its record appears in the list. Edit each new guide as you need
it: when you type a positive value, the guide will be above the
line/inside the ar; when you type a negative value, it will be
below the line/outside the arc.
- When you have added the perpendicular and parallel guides you
need, click OK to place the grid.

III. Editing a grid
You can edit a constructed grid. Here's
how:
- Position the mouse pointer on a guide.
- Do any of the following:
- Doble-click the guide.
- Right-click the guide, and then click Object Properties.
NOTE: When you want to edit a grid, do not click the base object
— the line or arc. Doing this will display the object's own properties.
