AutoCAD Civil 3D

[#1]

Hi guys

Been chatting with an architect in my office, and he was asking me if we could make our TIN surfaces smooth.  I cannot find a way, would it take a 3rd party program?  He wants it like the image i attached.  Any ideas on how to achieve this with a TIN surface?

You can't totally smooth a Surface and have it remain a Civil 3D Surface. You can however make it smoother by using the AeccSmoothSurface command. This will add point to the surface to make it appear smother.

You might be able to explode a copy of the surface and somehow make the 3D faces into an AutoCAD Surface and do something with that. But I've never tried that since the result would be for display only and not linked to anything in Civil 3D.

I dont need it to stay as a Civil 3D surface, its for visual, not to design with.

You could try:

Click Output tab > Export panel > Export to Civil View for 3ds Max Design. Then use the 3DSin command to bring it back in as a Mesh. Pretty much a guess but if you play with it you might get what you want.

That would only work if you had 3DS Max Design.

Hi, I cannot work out the dialogue box for that.  It looks like it can only export corridors?  Can you please explain step by step after you click on the Output tab > Export panel > Export to Civil View for 3ds Max Design ...............  What next?  Thanks

Help says: "Feature lines, corridor, surface, and point data can be exported with Export to Civil View for 3ds Max Design."The left side of the dialog has items you can check to include in the export. If you have a surface it will be listed. If not using corridors, ignore the right side of the dialog.

Note, I have never used this until just now so I don't know how this will look in 3ds Max

OK. Here's what I've come up with.

Copy your surface. Set the surface to display triangles I'd then suggest smoothing the surface. Then explode the surface twice to get 3DFaces. Use the CONVTOSURFACE command to convert the individual 3DFaces to mesh surfaces. Then use UNION to make them all one mesh. Finally use MESHSMOOTH to smooth it further. Say yes anytime it warns you about primitive solids.

That's about the best I can come up with without in depth study and trial.

When I Export to Civil View for 3ds Max Design, it saves it as a  .vsp3d file, but when I do 3DSin command, it only lets me use .3ds file types.....

As already said by Allen: "That would only work if you had 3DS Max Design"...
