Fillet function error, program crashes

malozog — Sun, 26 Jan 2025 15:06:53 GMT

Hi, I have something projects due this month and I have a problem with fillet function with 3d objects. Everytime I try to use the function my CAD crashes. I dont know what to do, I tried to use fillet function in the project below https://youtu.be/didklL8wmPQ?si=L9cCjkenZ_GknIb0

Your link goes to a video tutorial that’s not using AutoCAD. Do you have an AutoCAD question?

What version of AutoCAD are you running?

Enter About command, do a screenshot and share that here

Can you also share a sample dwg and do a screenshot showing what you’re trying to fillet that would cause the crash?

I'm with @paullimapa, please post your Autocad file in a state before you try to add the fillet.

But a first guess: Before adding the fillet you must union the cone and the upper barrel-shaped volume to one(!) solid (using the union command).

An additional hint may be allowed:

CATIA is a full parametric 3D Program, that means the 2D sketches are driven by parameters and if you modify the basic 2Dsketches the 3DModel follows these modifications.

In AutoCAD you also can create such parametric driven 2D geometry (using geometrical and dimensional constraints, as you perhaps did). But if you use these sketches to create 3D solids (extrude, revolve, ...), the solids do NOT follow if you change the 2D sketches. 3D solids (volume model) in AutoCAD are not parametric. In AutoCAD only surface models can be driven by paramtric 2D sketches (which must be in ONE plane parallel to the XY plane)

Furthermode in AutoCAD the parametric is restricted to the 2D environment only.

(That means, in AutoCAD you can not exactly follow tutorial which were created for CATIA or Inventor or Solid Works or Creo or ... other full 3D programs).

@malozog These forums are not for CATIA, and autoCAD is not a CATIA true alternate:

If FILLET command crashes your AutoCAD...

Have you installed the 2022.1.5 / 2023.1.6 / 2024.1.6 / 2025.1.1 Update yet? You kept your autoCAD version a secret, so I listed all the current ones. ABOUT command in your AutoCAD will confirm what you have installed. If not, get it from your Autodesk Account Page here https://manage.autodesk.com/cep/#products-services/updates
Restart your PC afterwards please.

If that did not help... Set GFXDX12 variable to 0 (that's a zero): a restart of your AutoCAD023-24-25 is required for it to take effect.

Also consider turning off LINESMOOTHING and LINEFADING variables: if still no relief then start GRAPHICSCONFIG command and change the 2D Display Settings pulldown from "advanced mode" to one of the other choices.

If all else fails, then turn off Hardware Acceleration as a last resort, your PC just can't handle what you may be asking of it, see if that fixes the issue.
