Geometric Constraints
Summary
When you apply a geometric constraint to a pair of objects, the order in which the objects are selected and the point on which each object is selected can affect how the objects are positioned relative to each other.
The following table outlines the valid constraint points for an object.
|
Objects |
Valid Constraint Points |
|---|---|
|
Line |
Endpoints, midpoint |
|
Arc |
Center, endpoints, midpoint |
|
Spline |
Endpoints |
| Circle |
Center |
|
Ellipse |
Center, major and minor axes |
|
Polyline |
Endpoints, midpoints of line and arc subobjects, center of arc subobjects |
|
Xref, attribute, table |
Insertion point |
|
Block |
Insertion point, nested entities |
|
Text, multiline text |
Insertion point, alignment point |
