How do I manipulate a body, or convert it to a form without it losing it's shape?

[tjtalma]

I have a solid that I created, there is an opening in it that needs to be manipulated, creating an angular hole. I need to slide the entire bottom over 4mm, and squeeze the ends so that there is a minimum of 16mm around the opening. The top is the correct shape currently. And there should be a smooth consistent transition between the top and bottom.

When I convert the body to a form it becomes a big cube, with the outline inside it. When I start to delete the faces that are not needed, it changes the shape, I do not want that. I just want the bottom of the opening moved 4mm. (See picture below, The blue edge needs to be manipulated)

Could someone post a screen cast of how to do this? (I've attached the drawing)

form wouldn't be the ideal tool for this.  attached is what your describing, but not sure it's what you mean.  I turned the history on so you can see the steps.

also unlinked that one component so it could be exported as a .f3d instead of a .f3z file.  generally speaking, .f3d files are preferred on the forum because .f3z can be a pita on our end.

Hi @tjtalma 

Few points you can follow while creating a design

• Use parametric modelling, This will help to go back to the timeline and make changes
• Constrain the sketches, Make all blue sketches turn Black

Also, i'm not sure why you are looking to 'convert it to a form'? can you explain?

Here is how we can move the sketch.

OK this makes sense, I didn't think of the loft command, but that is a great solution to what I was trying to do.

Thanks for the answer, Unfortunately that changes the top of the opening. I need the top surface different from the bottom surface.
