STL to IPT: How to cut onto a triangular surface

627 Views, 9 Replies

I have recently converted an STL file into IPT using Mesh Enabler 2013. The file is now a solid IPT file..however when wanting to extrude and cut onto the surface it does not work, the surface is made up of hundreds of different shaped triangles. Is there any way around this?? I would like to be able to modify the file and have cuts and extrusions on it.

 

Please check out the 2 screenshots attached for a better understanding. Thank you :smileyhappy:

Hi and welcome to the forum.

 

An stl, by its very nature, is made up of lots and lots of triangles, as far as I know there is no way around this.  I guess that you could try and combine a number of them over a flat area by deleting all of them and then patching the area, but this could be a lot of work for little gain.

 

Can you provide 1 to 1 screenshots as the scaled images loose too much information (i.e. I can't work out the exact icons/text in the browser bar, which could help to identify the problem).

 

Is there any way to post the ipt, which would obviously help us, to help you?

Sam,

 

Thank you for the response. Please view the attached images that should be alot clearer. I am unable to upload the STL file unfortunately..

 

If there is a solution to the problem then it would be great!

Why are you importing an STL file?

Can you get the file in a "better" format.. Like STEP or IGES..

 

IMO STL is ONLY for export to a 3d printer/Stereolithography machine,etc...

You say the extrusion doesn't actually work - yet I see an extrusion feature in the history tree.

Have you turned off the visibility of the stl graphics, maybe that is obscuring the view of the solid body?  (I didn't test to see if this could be the problem.)

STL is the format type that was provided to me (made up of many thousands of triangles), so I converted it to IPT using the Mesh Enabler add-in. It then appeared solid, however when trying to modify it, it does not work. Baffling!

The extrusion feature you see in the history tree has indeed been executed by me. You see, executing the extrusion/cut command does work (so therefore will appear in the history tree), but does not actually make any extrusions or cuts.

 

I haven't tried to turn off the visibility of the STL graphics...How do I do that?

Suggestion for the future.

Don't request/use STL unless you are a 3d printer or stereolith house. 

STEP or IGES are intended for this.. STL is NOT.
