Dimension in a plane different form XY #238

Closed subGm closed 3 years ago

subGm commented 3 years ago

Hello, I would like to add linear dimensions to some graphic objects placed in a plane different from XY (in this case parallel to XY with a Z offset). I would like to add linear dimensions to these objects, but the LinearDimension constructors only take Vector2 as paramters. Is there a way to solve this issue? Thanks

I used this workaround:

  1. Instantiated LinearDimension object with the constructor that takes Vector2.
  2. Rotated and translated the object with TransformBy method.

The Normal and Elevation properties defines the construction plane of the Dimension entity. The Normal defines the local plane and the Elevation the distance along the local Z axis. The Vector2 parameters are coordinates in the local plane.

You can use the TransformBy method since it changes the local plane of the dimension, but it is a lot more costly, it not only applies rotations but scales and translations too.

Thanks for your support.
