Coordinates and rotation information of blocks

[wim (Wim Dekeyser)]

Hi Don -
I’ve moved this part of the conversation into a new thread…

@doncstevens

Is there a way to find out the world coordinates of the insertion point of a reference file within the drawing into which it was inserted?

If you select a block and run ExtractPt on it, you will get the location of the insertion point.

@doncstevens

Insertion point has a specific 3-D coordinate within the world coordinates of the drawing and has three axis of rotation which define how the imported block since within the world.

The transformation matrix of a block instance can be retrieved - does the following thread help you on your way?

Read Transform Matrix of block Instance in FILE3DM

Hey All, I need to read the transform matrix of block instances with specific names in up to 26000 rhino files… I have successfully manage to read transform matrix previously, is a DOC… but… read as a FILE3DM its not working… While I can access the InstanceDefintions which returns a format InstanceDefintionGeometry, which oddly I can scale, transform and translate, however I cannot actually read the current transform information back from an existing file… Any leads, I really don’t want to s…
