    Make sure you have not got the 'Use Lightweight Assemblies' ticked in DesignSpark Options.

    Thanks for the suggestion but no change.

    Here's a file that appears correctly in PrusaSlicer and Solid Edge. I do not know how it was created. Don't appear to be able to attach file so here's a link to it https://www.prusaprinters.org/prints/10370-gravity-spoolholder-for-mmu2s

    No problem with the file.

    Try this. Right click the STL file and Open with Spaceclaim.

    You do realise that when an STL file is converted to a solid it will still keep all of it's facets on curved surfaces.

    Does the file show in the 'Structure Tree'?  If it does then pick the 'Home' icon on the 'Design' Tab.

    @Jacant Thanks again for responding.

    Tried "open with" Spaceclaim. No change except Start page is now the second tab. I note that in your screen dump the structures tree has both facets and solids whereas I have only facets. (I tried convert to solid which seems to work but window still dull gray)

    The file does show in the Structures tree but the two options on the Home item are grayed out.

    Sorry but I have no idea what the significance of "You do realise that when an STL file is converted to a solid it will still keep all of it's facets on curved surfaces." is?

    A screen shot would be good. Can you edit the Facets or Solid in any way?

    Sorry but I have no idea what the significance of "You do realise that when an STL file is converted to a solid it will still keep all of it's facets on curved surfaces." is?

    The significance is because if the model has many curves then they will be converted to a solid with many facets. They will not be smooth curves that you can edit as such. Each individual facet will be it's own flat face. As the image above shows. I have copied the 'Facets' to make two copies and converted one into a 'Solid'.

    To make it into a true smooth Solid, you would need to draw over the Arcs and Circles using the 3 Point Arc or 3 Point Circle tools. Then use these new Surfaces to Pull to the size you want. Deleting all of the faceted curves.

    This of course would depend on the complexity of the STL files' 'Resolution' as can be seen in the attached image, that shows the original solid and two imported STL files with different 'Resolutions'. These have then been converted to Solids, showing the 'faceted' curves.

    An STL file is an approximation of the surfaces of a solid split up into facets and again into triangles. The more triangles (Resolution) the smoother the model.

     

    So I assume that when you import the STL files you would want to edit them.

    BTW I do see the correct image in Spaceclaim viewer.

    Note that as I have no interest in "Download 3d models" I do not have IE11 and Java installed.

    I'm running win7 sp1 x64 Ult.

    I would raise your question as a 'Support Ticket'

    @Jacant Thanks for all you're efforts but I really don't want to do the "tech supports dance". I'm not wedded to DS, in fact the clunky way of generating text is a definite turn off. I really don't want to go Fusion or anything cloud based, any suggestions?

    There is no problem in contacting support. I have done it before and got a helpful reply.

    From the image you sent it looks like a Graphics card problem. Although the files have loaded there is no 'Graphics workspace window'.

    Can you open (File- New - Design) and create something? The 2D grid should show. If it does then try to 'Insert' the STL file. If the grid is still not shown then I think it is a Graphics card issue.

    Check this link. There is an Automatic graphics compatibility checker there.

    Well thats weird. I ran a couple of the tutorials so I knew that I could start a New file but now I come to try again the window just stays dull grey.

    A little while ago I had to reinstall Win from an image and so need to reinstall DS. So it seems that where the wheels fell off. I've tried reinstalling DS (cleaned reg before installing) a couple of times without success.

    On the install screen it advises that you check that the latest DotNet is loaded. You don't happen to knoe which version of DotNet DS uses?

    I note you run Win 7 SP1 64 bit. I run the latest version of Win 10.

    Thanks again for the info. The required version of DotNet is included in the setup so I assume it's installed automatically (manually installed anyway just in case).

    One thing that is nagging is that even after I cleaned the registry and re installed I was not prompted for activation. Is it possible to force a reactivate?

    BTW Video passed comparability.

    Yippee, that was it. Why it worked the first time I have no idea. For the recored I have Intel HD graphics 4000 and Direcr3D9 works fine.

    Thank you very much for your above and beyond efforts.
