Can't select objects while app is loaded

[trmaEGMSS]

I've been using a lsp called "ZPT Z VALUE" (attached) to show the elevation of points in autocad. It's been working without issues in the past.

Now my autocad no longer lets me select objects when I'm running this or any other lsp. The objects are highlighted when I move the fence over them but when I try to make the selection it just says "0 found". When not running a lsp I can select objects and delete them or do whatever I want with them.

The problem seems to affect every app i try to run.

I've tried everything I can find online for more than a week now but nothing changes the behaviour.

Welcome to the Community!  Can you tell us what version of AutoCAD you are running?  Did you recently do any kind of update?

[trmaEGMSS]

I'm running Autocad Map 3D 2024. It's a corporate machine so it may have updated without me noticing.

Did you test in many DWG files?
What about everyone else in your office?

Are you sure you have plain-AutoCAD POINT object types in your file? Find them using QSELECT, FILTER or SELECTSIMILAR commands right now.

What are your settings for PICKFIRST and PICKADD variables?
Are ALL of your layers thawed/on/unlocked?

Did you restart your PC yet?

Your LISP works just fine here in a DWG file that I added POINT objects to all over the place, in 2024-2024-2025 year versions for me.

Thank you!

The problem is that apparently the points are not plain AutoCad Points.

I tried creating a new point with the point command and  gave it a Z value and after that the LSP worked as expected.

How do I fix this? Is there a way to create a LSP that does the same thing but with objects too instead of just points?

I still don't understand how it worked the first time I tried it out, as that was also done on objects..

Hi, is it your objective to just get everything in your drawing to a Z of "0"?  @pendean does "FLATTEN" still exist in AutoCAD? (It's been a long time....)

[trmaEGMSS]

No, my objective is to have the Z value of each point written next to the point, with 2 decimal places.

Basically the goal is to do exactly what the LSP I initially attached does. The problem now is I don't know how to do that for the points (objects) I have from my trimble surveying equipment.

So the problem was indeed that the LSP needs actual points to work. It doesn't work with polylines or blocks.

I can explode polylines and have the LSP work but none of my blocks has actual points. How do I get autocad to insert an actual point (one that I can see whem changing point style in ddptype) on the insertion points of the blocks? All the blocks have a single x, y and z coordinate so I'm kind of baffled why the LSP doesn't work on blocks.
