Combine feature seems very strict

For example, if you take a cube, then slice through the cube with a plane, you cannot recombine the two resulting solids.  Is there a work around for this?  There are plenty of instances where you need to trim a solid when revisiting a design.

The process you describe is very easily accomplished without issue.  Take a look at the Animated GIF and you will see I split the cube body, the Combine it back together.

Then I wonder what causes the behavior I listed in my op.

Please submit a video or animated GIF showing your process and also the model you are using.  Make sure you attach the model that FAILS.  Open the model in Fusion 360, select the File menu, the Export and save to your hard drive.  Attach it to a reply post.

The failure happens when I stitch together a solid from a sketch from another solid.  That explains why it cannot combine, as stitching surfaces into a solid is an approximation.

 

This is unfortunate.  Is there a way to "loosen" the tolerance of combining two solids in proximity?  These solids are probably less that .005" apart at any point.

Can you File>Export your *.f3d file to your local drive and then Attach it here to a Reply?

No, I do not wish to share my project.  I figured the description would be a common issue thus specifics wouldn't be necessary.  If not, I'll sort it out on my own.  

 

I see that you cannot cut with a surface made from two lines either.  It's been a while since I used F360, so I am just picking up the nuances again.

That is the first time I have ever heard of this limitation.

Can you Attach a simple dummy file that exhibits this issue?

I would but I cannot get another project to repeat the behavior and I am just picking this up after a few years.  

 

I did something stupid and hosed it up I assume.  None the less, the issue was resolved by unstitching the solids and stitching them back together instead of using combine.  When I did this I noticed I had lofted a few surfaces together instead of extruded so they had a bulge I could not see.  That didn't really cause the issue but I am glad this occurred to some degree.  

 

All is well now after unstitching the solids then stitching them together.  I could see how this is the intended workflow versus dealing with solids.   

 

Thanks for the help!
