How to change the quote of a used ellipse in a sketch

zirkov

Hi Everybody,

I'm new to On Shape and modeling parts.

I am trying to create a two parts model which is basicaly a box that I will 3D print.

Part 1 : SHELL

Part 2 : LID

I managed to create the first part quite easily using the "SHELL" tool but i'm having a bit of a trouble to model the second part.

For the second part I created a new sketch on top of my first part using the "USE" tool to get some sketch line I need to create the lid but when I try to use the dimension tool, I get the following error : Cannot dimension this curve.

I'm convinced there's a simple solution to this problem but I haven't find it yet. I tried to look into the docs but did not find anything relevant and i'm running out of ideas to solve this problem.

I managed to create the lid but I really need to edit the dimension to get some space between the two parts so they can assemble smoothly.

Could you help me solve this problem ?

Welcome to Onshape. To create the clearance you need, it could be done via a sketch or sketches. An easier way is via Move Face. In the document (linked below) that method is used. To maintain the thickness of the inner extrusion, the Shell thickness is increased by .5mm. - Scotty

Hi,

Thanks a lot for your reply, that's exactly what I was looking for ! 

Do I need to mark this thread as resolved ?
