Thank you Jim for explanation.
The fact is that LC operates with library based projects.
Balanced size items are boost performance. For example if you lights up a big model with 200 of lights it will be rendered 200 times, which is very bad due to it's size. But if you have it divided on a small unique parts, duplicated some times or not, each part will has it's own light and will be rendered one time. The realtime starts here.
Our library items are high detailed and highly optimized for realtime rendering. This is a special job called
Designer/3D Low Poly Modeller. And doing such models need a lot of knowledge.
Another fact is that the CAD packages are not mind about 3D model's quality. Mostly you can't control how vertices arranged on volume and how they map to polygons. You can't optimize them with Normals mapping and UV coordinates. The exported 3D model of that will looks for LC like, for example, a .txt file for the book publisher - you have it but can't use properly.
We doing all our best to solve this problem. LC will automatically optimize imported geometry data, map UV and generate Normals. For the drawing time you can enable Draw and Light Backside engine, you can also Flip Normals if needed. All of that allow you to importing small objects, unfortunately it can't help on a bigger one.
The possible solution that we can propose you right now is to build in VW the .dxf library of items that you will need. And design the project in LC than.
By the way, v42 will have ability to load files directly without icon creation needed.
Other solution, we have a knowledge of how to recreate your VW drawing in LC. But we will draw it optimized from scratch in StudioMax anyway. This takes a lot of time, but worth it sometimes.
