Question

How do I eliminate unwanted lines in IsoDraw?

Hello,

I am importing STEP files into IsoDraw and getting random extra lines in areas that are actually smooth, flat surfaces. To clarify further, these are not the types of lines left over from cuts, corners or curvy shapes. They should not be there at all, and I have found no way to successfully delete them in 2D.

The lines tend to fuse with ellipses. I tried deleting the points of the lines, but that distorts the ellipses that are fused with the lines. I find no "break curve apart" type function that would disconnect the unwanted lines from the ellipses.

I am hoping there is something I can do to resolve this in 3D mode or upon import. The CAD experts I talked to at my company suspect it is a "format translation" issue with IsoDraw. I would like to avoid bringing the 2D graphics into another drawing program just to fix this because it might disrupt the metadata, and it's important that we keep that intact in our CGMs. Not to mention, this creates a bunch of extra work. The lines really should not be there in the first place.

Does anyone know why this is happening?

Any help would be greatly appreciated.

Thanks,

-Renee

P.S.: Anyone have success with adding multiple tags? It says to "use communities to separate multiple tags." I think this is an error.

When we first started using IsoDraw we had a number of issues with 'translations' of our models. In our case we worked with PTC directly as we use Creo (fka ProE). We ended up changing what they referred to as a 'recipe' file on the cadworkers that created our models.

I'd suggest checking with support to see if they can help in your situation.

If you want to try a few more things on your own, you can of course play with the preferences in IsoDraw when you project to 2D. You could also try a file type other then step. We've had good luck with iges as a starting point.

Thank you for your quick response. I am in the process of acquiring and testing some IGES files. So far, the extra lines are not showing, but I have not received all the IGES data yet to check.

I considered adjusting the import settings. While there are some adjustable settings for IGES, there are almost none for STEP (IsoDraw 7.2). So, the STEP file format seems to be hit or miss, unless there are SolidWorks output settings for STEP that I don't know about.

I also think PTC should address this problem with STEP, if possible. Although, there may be other factors I do not know about that could be causing it. If IGES turns out to be a better alternative for me, I will consider this question answered. I'll reply again when I am more sure of that.

Thanks again.
