How to fix auto intersecting geometries

[Anonymous]

Hi. When I finish and want to exit from sculpt mode, the auto intersecting error appears.

The problem is that I don't see any auto intersecting geometry, I ran both "auto repair" and "make uniform" function, and when the error popup appears, there isn't anything highlighted, so I have no idea what to look for.

If anyone wants to look at the project file, please tell me how to send it privately.

Thanks.

have you tried looking at it in box mode?  you should be in box mode probably about 80%-90% of the time your modeling.

looking at your topology, I would say you have little to no knowledge of how to manage the flow of your t-spline surfaces.

you can post your file here as an .f3d file, and I'm sure you'll get folks willing to help.  

you also might want to look into sub-d modeling techniques.  the concepts largely translate to t-spine modeling, but there are more tutorials on sub-d out there.

you're going to struggle till you get a handle on star-point placement.

running a crease through a star-point is also not a great practice.

Thanks for the tip, I'll look at those tutorials.

Do you know if there is a way to make the red highlighted areas ore visible? I can't find any.
Also, when creasing or uncreasing, it asks to select a vertex or edge, but it only lets me select edges, is it normal?

unfortunately, you have to hunt for the red faces, and sometimes that is a challenge.  If you want to share the model here (File -> Export as "Fusion archive" and attach it to your next post), we can take a look at it.  I can usually find these, but some models are harder than others.

crease command has always said vertices and edges, and has always only allowed the selection of edges.  just an inconsistency in UI.

There's not much you can do to make the red error areas easier to spot.  you can switch to wireframe mode and click on the "check conversions" button, which helps some.  The red error face shown here is folded inside the body and would be hard to see anyway else-

I think I spotted the problem from looking at your video.  Hard to see, but there is a bit of red here.

Again, if you can share the model, we can race each other to see who finds it first...

Thank you both.

I worked on it and finished, I could terminate it without any error.

It is a closed mesh, and I want to convert it into a body.

On the official tutorials it uses other tools which use a surface to close the open parts to make it solid, but mine is already all closed.

I found the option "Convert to brep", but when I do it it goes back into the timeline like it would do if I did just exit the tspline environment without any error, so it still has a tspline body, not a solid one.

What can I do?

[laughingcreek]

you only work on t-splines in form mode.  once you exit back to the design environment it will automatically convert to a brep.  where you can perform solid operations on it.  you only use convert to brep on a t-spline when you have the timeline turned off (DM mode)

Hi, I tried to perform operations like subtraction or join, but the tspline body can't be selected. It has a red "surface" icon rather than a body

Never mind, I went into the patch workspace, when using "join" it highlighted me an open face. Now it is treated as a body.

flying dark here.  gotta guess what you mean b/c nothing your saying is precise in meaning. (and you haven't supplied a model).

you've exited the form mode?  and you have a surface brep instead of a body brep? then you're tspline was open some where.  do a surface stitch on the resultant brep surface.  it will show red around the edges that are open
