Create points in center of spheres and export their coordinates

[Anonymous]

Hello all!

I am new to Autodesk AutoCAD and want to create points in the center of spheres-like objects within a 3D .stp file and then export their coordinates.

Up to now I got my .stp model to import, but cannot find a way to modify the spheres. Every time I try to mark the spheres I get the message 'object with unchangable attributes'.

Is this an issue created by me due to the import of a non .dwg file format? Is there an easy way to get the coordinates of the sphere centers?

Thank you and best regards

HI @Anonymous,

You sent me your drawing files and it was indeed a single solid which made an extraction difficult based upon the existing components.

I created a sphere that contained a point at the center. I made this into a block and copied this sphere block to each of the spheres in your model. This helped me to verify that I had located the centers visually as I copied it around your model. I then used DATAEXTRACTION to extract only the points and their locations. I inserted this resulting table into the drawing file. It can be updated as necessary by rt-clicking and selecting Update. I then selected the table and used Export to create the CSV file.

You should still be able to osnap to the center of the spheres in order to place a point there, then dataextract the points.
