TIN surface for Excavated vertical face

[nilesh33]

Hi friends,

I have 3D faces of vertical excavated face. Now I want to build TIN surface from this data into CIVIL 3D.

Because of crossing lines and different elevations at same X,Y points, output becomes "weird".

Output should be what we can see in image. (Image- 3D faces selected in object viewer)

I know we have to violate the "TIN principle" to get this output.

Any suggestions would be appreciated.

Thanks & Regards,

Nilesh

Morning,

Personally, I would select the whole lot and rotate them by 90 degrees before adding them into the surface, so the vertical face is 'flat' to all intents and purposes. This removes all of the vertical issues as you suggested but depending on what you're doing might not serve your purpose.

C3D doesn't handle things that are near-vertical very well and somebody better than me may have a better workaround.

Cheers,

Kevin

Thanks Kevin,

Yes I have tried this procedure but not able to rotate the final surface.

Thanks once again.

Yes, you won't be able to.
You need to rotate all the faces before creating a surface. Then add the newly-rotated faces to a new surface. Don't rotate it back after (you won't be able to). Leave it on its side, so to speak, and change the view if you really need to.

You can not create a true face that is at the same x,y and different z in a surface this has not been aloud since the beginning. You can create an approximate, by changing x & y by a very small amount like .01 or .001, but it must change slightly.

Hi,

Yes I have exported points to CSV and adjusted the X and Y slightly for points of same elevation.

Now we have solved the crosslines and same z elevation problem. 

But we need to find the way, how it will triangulate to nearest "Z" value along with X & Y

This will solve my problem.

Thanks for your valuable inputs.
