Description
A dimension style is a group of dimension settings that determines the appearance of a dimension .
Remarks
The active dimension style determines the appearance of new dimensions created in the drawing.
To change the style of an existing dimension, use the StyleName property found on the dimension.
When you create a dimension, the current dimension style is associated with that dimension. The dimension retains this dimension style unless you apply a new dimension style to it or set up dimension style overrides.
The picture below shows where the vdDimstyle's properties apply to vdDimension objects.
