Problem selecting outermost sketch profile for extrusion

[gabriel.dsilva]

I drew an offset profile around an existing part. I want to select that rounded rectangular profile and extrude a new body, without any holes, to use as a stock model for machining. I would like to do this with a second body in this same part file rather than create a new component file and an assembly.

I cannot select the outside sketch edges that I drew. The selection shown only produces an extrusion of the blue area. I drew a loop and I want to extrude a solid from that loop. Is this possible?

Hi , 

attach your file

you just have to select all the other profile regions in the middle.  You can use window select, as well.

That works. It's strange, because in all other CAD or CAM software I've used, internal edges are ignored by default and must be explicitly selected in order to exclude them from an operation.

Thanks!

when you extrude from a profile in a sketch, it's only going to use profiles that are defined in that specific sketch.  it won't grab edges from solids to use as as a profile.  unless you project those edges into your sketch.

do you have this check on in your preferences?

if so, then when you selected that face to put a sketch on then it projected the edges of the solid into your sketch for you.  just to make it supper obvious that fusion has done this for you, those projected lines are essentially invisible, making them easy to find and figure out what is going on.

sarcasm aside, go to your sketch and turn everything else off.  do you have profiles from the face of that solid that you didn't explicitly draw?  those are from that setting pointed out above.  I would suggest turning it off.

What if turning it off doesn't make it stop projecting the surface? 

I turned it off, no change. Turned off and saved the project, no change. Turned off, saved, closed, reopened, no change.

Window select leaves the holes unselected for some reason.

once the edges were projected it's done.  turning the preference off isn't going to toggle edges that where already projected.  only effects new sketches.

would need to see what your talking about.  attach a model if possible (export as .f3d, attach to post)

OK. Thank you. I thought it might be the case. I'll make sure that's off from the start .
