Removing Multiple Fillets

[Anonymous]

Hey, I am new here and learning. I have some files created by someone else in Catia. These are .stl files and load just fine. I am able to do what I need. 

I am however having some issues. The guy who made them when into great details with fillets in some complicated areas. There is alot. The issue I have is in order to remove the fillet I must remove all of the "chain" so to speak of fillets in that area. I understand that but its often not clear what need to be highlighted. 

I need to remove alot of this as I need to alter the design significantly. Is there a way to choose a "chain" of fillets automatically as I am not sure what I need to remove? 

Excuse my non "technical" terms here. I am new. I do understand that you cannot remove just one part of a fillet, but I dont know what all needs to be removed to do what I need to do if that makes any sense at all.

Hi,
without seeing the object including its constructive conditions, no recommendation can be made.
Please share the design.

Stl is the worst possible format they could have given you..

There are no fillets in a stl file - only planar faceted triangles.

Ask them to give you STEP, IGES or even native CATIA format.

from the description of what the OP has done so far, I would guess there was a typo and he meant .stp.  Hopefully @Anonymous will post a model, or  at some pics so we'll know for sure.

I’m sorry guys. Yes .stp. 

I am doing a short screencast now, I will have it up here shortly. I apologize. I can’t share the file on this one but I will share some detail. Even if I could find a way to remove all the fillets, I can re-fillet what’s needed after I make the changes necessary.

Here is a screen cast. This is one of the less complicated models. I need to remove all the fillets you see so I can make some slight tolerance changes. It wont allow those changes with the fillets in place. When I attempt to remove what I think is needed to clean a edge I get the error "Cannot delete individual faces" or "Error: The selected faces could not be deleted. Ensure that faces are only selected from a single body, and that no duplicate or invalid geometry is included in the selection."

Here is a screen cast of the amount of fillets and how they tie into each other.

Hi,

delete fillet by fillet you don´t want.

Yeah my thoughts exactly however it doesnt seem to matter what I select or if I select it all it errors out.

Have you tried the 'Find Features' command? It might make it easier to select the fillets for deletion, supression or adjusting the size.

I have, it doesn’t find very many of them. It’s rather frustrating. I wish fusion would show me the chain of fillets needed to removed what I want. I feel like it’s a guessing game. 

below is a example. I did figure out how to remove it but those in the other screencast are proving to be a pain.

I was afraid that might be the case but thought it was worth suggesting.
