RECOVERED CONVERSATION EXCERPTS
USER MESSAGES:
1. I REALLY NEED A PIECE OF EQUIPMENT FROM NAVIS WORKS AS A MODEL. I DONT NEED TO EDIT IT OR ANi JUST NEED LOCATIONS OF SMALL IMPORTANT PARTS. USING FBX AND BLENDER I AM GETTING THIS
2. It looks clean in navis works
3. this is all i have
4. i dont know how to use CAD Exchanger i don't see a link for any of their stuff only brochures

ASSISTANT RESPONSES:
1. What you're seeing in Blender is not really a Blender problem. It's a garbage triangulated mesh export from Navisworks. The fact that the top frame looks reasonable while the lower half turns into a pile of random triangles is a huge clue. A few things are usually happening: 1. The NWD contains a mixture of: - Real CAD geometry - Coordination geometry - Point cloud / scan data - Proxy objects - Vendor equipment models 2. Navisworks FBX export tessellates everything into triangles. 3. Blender imports exactly what it receives. If the source geometry is already broken, Blender cannot magically reconstruct it. [embedded media omitted]. Before you go any farther Answer this: Does the equipment actually look correct…
2. If it looks clean in Navisworks, that's actually good news. That means the geometry likely isn't bad in the NWD itself. The corruption is happening during the export/conversion process. Looking at your screenshot, I suspect one of these is happening: 1. Navisworks FBX export settings are too aggressive When you export the FBX, look for options related to: - Faceting factor - Triangle count - Merge geometry - Convert primitives - Normals If Navisworks is exporting with a coarse tessellation setting, detailed components get destroyed.. 2. Blender is importing with the wrong scale/transform I've seen Navisworks FBX files come into Blender with: - Bad normals - Negative scales - Broken transforms Try this in Blend…
3. I think you're on the wrong page. You keep landing on the marketing/brochure pages. What you want is the actual CAD Exchanger Lab download/trial. CAD Exchanger offers a trial version of CAD Exchanger Lab, their desktop viewer/converter. [embedded media omitted] Try going directly to: [embedded media omitted] Then: 1. Click CAD Exchanger Lab. 2. Look for Try for Free, Free Trial, or Start Trial. 3. Create an account if prompted. 4. Download the Windows installer. 5. Install CAD Exchanger Lab. CAD Exchanger Lab is the desktop application that can import/export many CAD and mesh formats. [embedded media omitted]. However... Based on everything you've shown me today, I'm no longer convinced CAD Exchanger is going…
