Editing STEP files

[vilts]

Hello,

I have a STEP file which needs a little modification before I can mill it. No matter what I try, I just cannot get it done. I can quite easily remove "stuff" with PressPull in Modelling environment. And sometimes even add, when the surfaces are not curved.

But now I need to extend one complex surface out 4mm, but I cannot find the proper tools to do it. Target is in the attachment, what I want to do is to fill up the space smoothly between the brown extruded bit and rest of the body. I created 3-point construction planes where I needed the surface to be, drew the sketch lines, but in no way I could fill up the contours afterwards...

How should I approach this?

i'm not sure what you are looking for. Do you want to remove the large v notch or are you trying to blend the top of the brown box into the adjacent geometry?

Hi. Yes, I am trying to blend them. Basically I want to extend the curved part of the main body outward a little.

I did get it done somehow by creating bunch of extrusions and then cutting them, but I am thinking that there should be a better/easier way to accomplish this.

You may be able to use the Replace Face command in the Modify drop down menu to obtain an acceptable solution.
