Trouble after importing .dxf file

I can import this .dxf file into SU (2023) and save it, but as soon as I try to do anything to it, or even select a part of it, and paste it into a new drawing, I get either a freeze in SU requiring a force quit, or a bugsplat.

Any advice? I did manage to get it to print, so maybe I should just work from the (dimensioned) printout, and redraw it?

@colin, is there anything wrong with the format of the file? It was originally saved as a .dwf, and I used an on-line converter to read it and output it as .dxf.

It views correctly in AutoDesk’s online viewer as a .dwf, and looks correct when imported as a dxf into SU, but then misbehaves.

I imported the DXF file and had a crash.

Then I restarted Su and after another import, I copied the model and pasted it in a new file.

Then I exploded the model, copied only the front view of thew the arched window and copied that into another SU file. I also purged the model.

I saved that file. Find it below.

You will see that I resized it so that it shows correct dimensions.

Please note that all the edges came in as poly lines.

Try the file and let us know if it seems to behave correctly.

I find that 3 Megs for such a model is a huge file. All the dimensions came is as geometries. This can be cleaned.

I try save as your file to autocad dxf 2010 then import s4u_importdxf.
It works fine.

Thanks to both of you. Will look at the skp files late this evening.

It all came in fine for me and didn’t crash

It looks much better if I open it via trimble connect though and some of the data structure remains

I realise I’m not sure what to do with the imported polylines - instead of Sketchup edges, they are like little tram tracks.

I think I might as well draw it from scratch in SU, rather than try to use the imports - which by the way do NOT now crash SU.

Thanks though - at least I have something usable to start from, when redrawing.

22 years or thereabouts since I first drew this in AutoCad. Forgotten how, now!

But it made a very handsome stage set for Tom Stoppard’s play Arcadia.
