I need help how to fill up a space in a step file .

richard_conen · June 21

Hello,
I have a step file downloaded from printables and imported it in oneshape.
https://cad.onshape.com/documents/826a126dbe9e8613ca44c134/w/b94a57fbf780ef71657984e6/e/08b6c1b9589fe075e48d5ffe?renderMode=0&uiState=667598f395d23821c532e8a1
I'm trying to fil up the big hole bolow to make room on the inside of the part. I tried a lot to do this but i don't know the right steps to do this.
can somebody help me ,or do one side so i can do the same for the other side? i'm trying to learn to edit files.
thanks for the help

This one is difficult. Here is one approach. It's not a perfect continuation of the rounds. But for hobby 3D printed parts, it should be good enough.

To get it perfect would require a lot more work. You'd have to recreate the tangent edges of the rounds with new curves, then turn those curves into surfaces. Unless there is another way I'm not seeing (very possible!).

I tried a lot of things too. This is not easy to fix. The main surface is a simple extrusion, but the fillet around the edge is variable and it's tricky to get rid of the pocket.

@GregBrown's Extract FS to see if I could clean things up if I had the untrimmed surfaces, but trying to get the variable fillet to trim to the surrounding surfaces didn't go well.

This is super, I can work with this.it is indeed for 3d printing so this is perfect. Never used the "fill tool" before.
Thank you for the help, verry much appericiated. ( sorry for my english, I speak dutch )

thanks for the help, It is very good for me, It is for 3d printing and if the curve not perfect, that is no problem.thanks both for the quick reply and work.
Greetings
