Generate 3D Face from 3D Solid

Hi all

 

I have created a model, by lofting a shape along a curved spline path. The model propertie is currently '3d Solid' what I want to do is generate a 3d Face off of this model.

 

I have exploded the 3d model and that gives me a surface, bu the dilema is that I do not khow how to 'trace' or turn this surface into a 3d face format. What I was thinking is that if the surface could be exploded into induvidual elements I would be able to draw over the surface with 3d face and then have my model, but a issue with this is that I cant explode the surface into elementary elements AND the 3dface tool cant generate curves....

 

In short would any body be able to tell me how to turn a 3D model into a 3D Face or a Surface into a 3d Face.

 

Thanks very much!

3DSOUT  and   3DSIN  (but these commands no longer available with Autocad 2009 and newer)

With the 3D Modeling Workspace active
Click on the Mesh tab
Click on the down arrow in lower right corner as shown.
Set the Smoothness level (caution - setting to 3 or 4 will create large file).
Click Select Object to Tessellate and click the solid.
Explode the resulting mesh to 3D Faces.

Hey JDMather

 

Thats exactly what I wanted and it worked, but the probleme is that when I hit create mesh I get the following message:

And when I hit convert, it approximates the shape of my model, (I used setting 4 smoothness aswell), and it looses the curves I want, here is what happens:

Thanks very much for your help so far!

Attach images here - I see no reason to go to another website.

Yes, it will be an approximation.

 

If you can  find a software that will convert stl files to 3D Faces you might get better results.

set facetres to control stl resolution

stlout

convert stl file to 3D faces in alternate software.

Ok I see, so there is no way of doing it in AutoCAD?

 

I think there is a possibility of doing this using AutoCAD Civil 3D and using the MASSELEMENTCONVERT tool but I am not sure if it will work and will be difficult to access the software.

 

"set facetres to control stl resolution

stlout"

 

Is this the procedure for saving the 3D Solid to stl file? Apologies for my bombardment of questions, but finally, would there be any texts to recommended software to do the above? I am relatively new to this.

 

I appreciate your help, many thanks

While in the Loft command, use MOde and specify a surface instead of a solid.
