BUG: Extrude ignoring certain profile selections.

When I do an extrusion, some of the profile selections are getting removed when I click OK, and are not extruding. Editing the feature and re-selecting the profile does not solve the problem.

The screencast shows the problem:

Can you export the f3d file and share here?

Thanks Mark

Yep, known profile detection bug,

use another extrude with join.

I see the plate is not constrained in either sketch.

Your sketches could be 1/4 the amount of work you put in.

Might help....

This is actually caused by inaccuracies in the sketch, I think the preview is done with lower tolerances but when you click OK the model is generated to a higher accuracy and fails. If you move the circle slightly the apply tangent constraints it works correctly. You are making this a lot harder than you need in the other component, you should make use of feature patterns and keep the sketch simple.

Here's how to fix the extrusion.

@jonwienke Here's a screencast demonstrating how much easier this is if you use feature patterns then projection for your second sketch. File's attached.

The problem is absolutely NOT "inaccuracies in the sketch". The entire sketch is drawn on a single plane, and all of the circles and lines were placed manually by entering the coordinates and dimensions. If there are any "inaccuracies" in the sketch, it's because other bugs in Fusion are corrupting the location coordinates.
