constrain center point rectangle sketch to a plane

[Anonymous]

I created a simple rectangle sketch and extruded it.  I then created a "midplane" that was down the center of the rectangle body.  I then attempted to create a "center rectangle" sketch with the center point constrained to the plane - but-  apparently in F360 you can't align sketch geometry to reference geometry.  After goign through a bunch of the forums, I tried creating a projection of the plane into the sketch, this worked and constrained the sketch geometry, but when I went to create a cut extrude, the projection line had bisected my rectangle sketch in two.  I was able to select both halves of the rectangle, but when I created the extrude cut, while all of the existing geometry wsa removed, some sort of phantom planar surface remained at the bottom of the extrude cut.

I've attached a screenshot.

This seems like an increadibly rudimentary task - so I'm hoping I missed something . . .

Thanks for posting!

You did everything correctly.  Yes, the key is to project the mid-plane into the sketch.  If you don't want to have to select both halves of the rectangle, you can convert the line from the projected plane into construction.

Regarding the "phantom plane", I'm not sure what in the screen shot you are referring to.  In that image, I can see that your sketch is still visible, is that what you are seeing?  It also looks like you may have hidden lines visible.

Could you possibly post another image with the sketch hidden, or post your model?

thanks,

Hi Jeff,

Thanks, that is a little convoluted vs Solidworks, but it does indeed
work. The other good point about this is the "phantom plane" I referred to
does not appear once I turn the projected line into a construction line. I
think F360 wasn't considering the extrude cut I was making before a true
cut when the sketch was two separate paths. With a single path the issue
does not occur.


I'll go back an mark this as closed
