VISUALSTYLES
Creates and modifies visual styles and applies a visual style to a viewport.
System Variables
SURFACEASSOCIATIVITY
Controls whether surfaces maintain a relationship with the objects from
which they were created.
SURFACEASSOCIATIVITYDRAG
Sets the dragging preview behavior of associative surfaces.
Create Geometric Relationships between Associative Surfaces
Use geometric constraints to constrain and restrict surfaces. And use
mathematical expressions to derive surface properties.
Use Geometric Constraints with Surface Profiles
Just as with 2D drafting, geometric constraints can be used to restrict the
movement of 3D surfaces. For example, you can specify that a surface remain
fixed in a perpendicular or parallel location to another object. In the example
below, an offset surface is locked in a parallel position to its original surface.
Constraints are applied to the 2D profile object used to create the surface, not
the surface itself. Use selection cycling to be sure that you are selecting the
profile curve and not the surface or the edge subobject. See
Apply or Remove
Geometric Constraints
on page 373.
Use Mathematical Expressions to Derive Surface Properties
Dimensional constraints are user-defined expressions that are applied in the
Properties Inspector for that surface.
