View Full Version : AutoCAD to Lightwave conversion

11-10-2005, 06:23 AM
I am working to import some 2D autoCAD surveys into lightwave. The only way I have found to do this without significant losses in data is to import the dxf into CorelDraw and export it as an adobe illustrator file. This brings the drawing in accurately, but the scale is completely off as well as the object center which is important for the transfer between several programs. I import the drawing into CorelDraw in English units (1 unit=1"), but I can't figure out what units coreldraw exports in and what units modeler imports in to get the right scale. Any ideas on what is going on between the export in coreldraw and the import in modeler? Thanks

Can you export the DWG as a 3DS file?

yes, but it is a 2D line drawing and many of the features don't come over right if at all.

Have you tried the EPS format? That works well for 2d.

doh!,.. just read the rest of your post. I generally import the file then scale as needed.

Sometimes I will use a background template image as a guide as well

Version 2 of LWCad is said to have more import options. But it's not out yet 8~


I've used this with some success,.. when it was called Pixel 3d Pro. I've not tried this version.

Accutrans 3d does an excellent Autocad to LW conversion with all kinds of options. www.micromouse.ca

Thanks for your help everyone. For now I am just going to keep scaling it to a background template. I was just hoping to understand what was going on in the background as far as conversions to make things simpler for the future. I appreciate all your input and will check out some of the plugins.
