I am trying to make a graph in order to convert a 2D drawing into a 3D model.
In order to do this I am wondering if it is possible to get coördinates from an insertionpoint of an 2d CADblock so that i can use those in an excell sheet to place 3D objects.
If you need the Geometry Position in X, Y and Z as input for your script, then you can simply use a DATAEXTRACTION for that which will export out all coordinates to Excel, csv or txt.
If you want to do everything in Dynamo, the LinkDWG-package, as mentioned by @ngochungwru, is an option. You place the block(s) on a new layer and import all the objects on the chosen layer, see picture below. The output will be a list of the insertion points.
