Thanks for sharing those! I slightly modified your 4th macro to turn the camera at 180 degrees instead of 90 degrees, because this is handy when modeling cars.
-
Reverse camera view
-RotateView a 180 l, -RotateView a 180 r
This is a macro that I created to overcome one weakness of Rhino’s default ! _Line _Tangent _Pause command. It will ask for a planar object to temporarily align the CPlane to it during the command, then it will revert to the previous CPlane.
-
Line: Tangent and perpendicular to curves
! _CPlane _Object _Pause _ProjectOsnap _Toggle Enter _Pause _Line _Tangent _Pause _Pause _Cplane _Undo _ProjectOsnap _Toggle Enter
Two macros for creating of a vertical dimension or aligned dimension directly in the Perspective viewport:
-
3-D vertical dimension
! _CPlane _Object _Multipause _Dim _CPlane _Undo -
3-D aligned dimension
! _CPlane _Object _Multipause _DimAligned _CPlane _Undo
This video shows how to use the 3d dimensions:
