Unable to edit face

[andersbitsch]

Hi

I am trying to recreate a shoe last from a 3D scan.

I have build the general shape by slicing the scan and tracing the outline of core parts of the last. Then i have used the loft command to connect every sketch.

Now i want to make the last adjustments to the shape to make it fit the scan more precisely. This i want to do with the Edit face command.

But every time i try to pull or push a face, even in the smallest manner, i get an error messages saying that it is not able to replace the face.

It sometimes changes whether it calles it "Camfer/fillet" or that it is unable to replace the face. 

Does anyone have an idea what the problem might be? I have another file just like it just build on another scan, but in that i have no problem editing the faces. I just dont know what i have done wrong.

Thanks,

Anders

It seems that if i delete the fillet i used to even out the toe section i'm good to go. Can anybody explain why that is?

Is capture Design History enabled in this design? It looks like there is a fillet command that is failing.

After lofting, did you patch and stitch the shape into a solid body and then add a fillet? If so, what happens if you do the Edit Face prior to patch/stitch and fillet?

If you don't mind, I would like to look at the issue on my side. Feel free to e-mail me the archive file *f3d (Use export archive from main application menu) at Nathan (DOT) Chandler (AT) Autodesk (DOT) Com.

Thanks,

First off, awesome mesh model!

The error message appears to be an issue with the rebuilding the fillet command once the edit face command is completed. I note that if delete the fillet command, the Edit Face command will execute successfully. 

A couple of suggestions you may try is to use the Sculpt > Loft command first. This will generate a Sculpt Body (T-Spline body) which can be convert to B-Rep geometry later after the clean up is done.

Another trick may be to use the Patch > Loft command to create a surface body initially. This is much easier to manipulate in the Edit Face command since the geometry doesn not have to convert back to a solid body, but can simply become a surface body (no enclosed volume). After you are done tweaking with Edit Face, you can use the Scultp > Patch command to close up any open gaps in the surface. Next, use the Sculpt > Modify > Stitch command to convert the surface bodies into a solid body. See the below video for detail.

I hope this helps. Please let me know if you have any questions. 

Thanks

Thanks, that was exactly what I needed! It seems to me that the Patch loft is the most precise tool compared to t-spline loft which gives a rather wavy mesh of faces.

I must say I am amazed by the customer service you guys give in this forum! Keep up the good work!

Best regards,
