Yost Group, I am working with the acad manager of The Glosten Associates, inc. They design ships. I need the best info on the best drawing methods for the cleanest dxf export and import into 3DStudio. We have made preliminary tests with bad results which give only stray lines here and there, no solid surfaces to work with. Could they have drawn the mesh in the "wrong" way for 3DS? I believe it was done using 3d polylines. I am going to recieve more detailed info on how the file was produced. Cary Kline, the manager of the CAD department is deep into AutoCad products and is trying to develop the animation/presentation side of his business. For you information, the vessel is an Artic Research Ship commissioned by the University of Alaska. We would appreciate any help you can give at this point. I believe the problem is a simple one, but I am just unfamiliar enough with AutoCad not to know for sure. I know I have given you very little to go on, just trying to get the juices flowing, or perhaps the answer is immediate <g>.

Greg, Hi, long time no CIS. We are developing new tutorials for 3ds3 fot the PPT. Check it out. On the Acad to 3ds problem. Does the acad model shade? What version of Acad is being used? Did you see it Rendered in Acad12???? What were the setting used to make the DXF file?? This info will help people here to help you. Good to see you here. PAT

How are things going in WA? The Acad drawings have to be created using 3D faces. Plines have no surface info attached. The could use the plines in 3DS (dxf format) as shapes to place along a path to create the hull.

Ted, Actually a closed Pline is meshed in the 3D Editor as a 2D planar object. An extruded pline is meshed along its extrusion direction and if its extruded and closed it will be capped top and bottom. You'd be suprized at what some entities do when their imported into 3DS. Steven

Steven I meant to bring the plines into the shaper to use as shapes along the path in conjunction with Deform Fit. It would require editing to make all shapes have the same number of vertices but should work ok. Sorry for the confusion……. TedB

Hi Greg, You will get a better response from other forum members if you post your question in section 1 where more people are likely to see it. Regarding DXF import to 3D Studio, it all depends on what entities you use and which module of 3D Studio you bring them into. 3D Polylines for example only come into the 3D Editor if they are closed or extruded. Phil Miller, my co-author on Inside 3D Studio, wrote a whole chapter on DXF import into 3D Studio. Repost your question in section one and he'll probably jump right in. Steven
