help joining faces

[GD1224]

Hi guys 

I have a file of some aluminum extrusion. I am trying to join the faces all the way around into one face. This is so I can press pull it 0.5mm bigger to make a slightly larger cut out for my model. Resulting in a print that will be able to have the extrusions slide into  

Hope that makes sense ive attatched a pic 

Thanks, Josh

You want to use Surfaces for this operation.  The video will explain how.  You did not attach your model so I used a short section of 40 x 40 aluminum extrusion I had.  I am attaching the model I used, both pieces are components and they are grounded in place to show you the 0.5mm enlargement.

Edit:  If you just want to create a cutout, you can stop at the expanded surface operation and use it to cut your hole.

thank you! It only lets me offset 0.27 and nothing more it isnt enough to achieve what I am going for. Might have to try something else. 

Thank you for your time much appreciated!

I would like to try the process on your aluminum extrusion, please attach your model.

Try solid Thin Extrude > Cut - with the original sketch profile, wall thickness equal to clearance value.

Might help....
