Fail to extrude circle inside obj for embeded magnet

[markwhitnell717]

I created a simple rectangle and extruded it...made a center plane on xy axis symetric.  Constructed circle on center plane.  Can not extrude the circle two ways for embedded magnet.  Constructed vertical center plane and did a section view.  then selected the circle, now it can be extruded...what gives?  I can do this two way extrude in Onshape, no problem.

I am adding to this post.  After extruding the circle in the setion view analysis, the magnet hole appears.  If I turn off the section view in the browser, you can not see the extruded hole any longer...you can see the magnet hole in Onshape in section view as well as the normal view.

Seems to work for me.  What are you doing that is different?  One thing to be aware of:  Any planar face can be selected for Extrude.  If you have a sketch embedded inside of a solid, all faces of the cube will also be selectable.  You may have to use Select Other (long left mouse click) to select the profile of the circle.  If you have only one visible sketch with one profile, it will be auto-selected (as in my video):

You are correct,,, for some reason I could only select the plane the circle was on...now I have the clue...select profile if a plane is only selectable...Thank you, however in order to see that you did indeed make a magnet hole I have to view with a plane perpendicaular thru the hole, I can't see it otherwise....unless I am missing something again.  I made a plane thru two holes, but I have 4 holes one at each corner...I made another plane thru the other two hole...is there a way to view both section views at the same time?

sorry, but I don't know what you mean here:

"however in order to see that you did indeed make a magnet hole I have to view with a plane perpendicaular thru the hole, I can't see it otherwise."

Here I can see that there is a hole, and the view is not perpendicular to the hole:

I also am not sure what you mean here: 

"I made a plane thru two holes, but I have 4 holes one at each corner...I made another plane thru the other two hole...is there a way to view both section views at the same time?"

But, the short answer is:  No, you cannot have two section analyses visible/active at the same time.

Perhaps sharing a video or screen captures would help

Hi,

maybe you need another opacity setting?

Please show a screencast of your process and share the file.

That is great, thank you, Mark

Ok, I got what you were teaching me, thank you...here is the simple box I made with 8mmx2mm magnets embedded at each corner...the circles are 8.14mm dia, a magnet

plane 17.57mm above TP with extrude hole 1.93mm high, gives .5mm cover on top.  Box is 100x125x25mm.  The Top magnet plane is at 22.43mm above TP
