Remove from surface (dwg import)

Hello

Quite new to Rhino…
How can I remove this from surface? Item is imported from dwg:

Hard to know what type of object this is if it was imported from a dwg. If you click on the object and in Properties it says that the object is a polysurface, you can try the following:

Call the command DeleteHole. Select the surface that the letters are embedded in as the target surface. On the command line, you will see an option “All”, set it to Yes. Then click on one edge of one letter, they should all disappear.

If the object is not a polysurface, it may be a mesh, in that case it’s quite a bit harder to fix… Post the object if you can’t get it to work.

Hello

Thanks for helping.
The depth of the letters are removed, but something remains on surface:


That is destroying the solid object exporting this back…

OK, on the remaining holes, can you try the command Untrim and click on the edge of each opening (use All=No in this case)?
