What gives? Just spent hours working on a project loading V5 in my new machine, and no way to export .obj? Ver 1 easy peasy save as. You guys messed up a very nice program, and I find it very low of your company not to allow me to open another rsdoc created by another version. Figuring that I would be able to open it up and convert thru ver1. I am dumping your platform for another so that I can export to an .obj to slice into G-code.. Shame on you for wasting my time Dissatisfied

@digitheadman - Please make sure you have the translators program installed for DSM v5. You would have been guided to this by the install wizard when first setting up v5.
Please refer to the FAQ here for assistance:

The .OBJ file format is available in all versions of DSM

@billd700 Thank you for your feed back. I already deleted it. will reinstall. I didn't see any file options save as or selections during the install process. Just the step one button and step 2 button, done. The other version I don't remember doing that with, but it was a few years ago. ver1. will try again.

I started my adventure with DesignSpark 5.0 and... I hated it. The program is slow (changing to OpenGL driver slows it even more), has many flaws (drawing rectangle from the center by enterning dimensions ruins it), hangs (when trying print preview), and freezing on using several 3D functions (like "Move->Create patterns"). I have very fast modern computer with Windows PRO 64-bit and 32GB od RAM... 2 days ago I got rid of it, and today, I installed old 4.0 version - and you know what - RUNS SUPER FAST, with no freezing so far. Pity I cant open none of my test designs from 5.0 :P

@Tom66 Hi, it might have something to do with the graphics card driver you have. The design operations you mention are quite basic; we have tested on multiple machines and DSM v5.0 can do them effortlessly. Can you please create a DesignSpark Mechanical support ticket here ( and send us the log files from when you used v5.0?

Here are instructions how to get those log files:

We are looking for the ones labelled 'SpaceClaim' and the timestamp next to it will tell you when they were generated (so you can filters ones from v5.0).

My stl exports have gone from 20kb in DSM V4.0 to 2.5Mb when exported in V5.0. Same file. Only now I cannot open the file with V4 anymore and the file size exported from V5.0 is too large to slice. Do I have a setting incorrect wrt to stl export in V5.0 please? Is there a fix for this problem?

@PetrForejt Due to technical reasons, the polygon tool is available only with constraint sketching mode off:
