Can't see '2-plane' axis thru XY and 'plane thru Z-origin angled -45 deg.

Just trying to sketch a simple octagon with rounded corners.

Here's my thought process...

0) Sketch plane = XY.

1) Construct a couple of 'angled planes', one +45, the other -45, thru Z-at-origin.

2) Place 8 circles radially around the origin on (or really close to) the planes , dimension their radius.

3) Make them coincident with the planes XZ, YZ, +45Z and -45Z.

4) Dimension their centers radially from origin.

5) Connect lines to tangent points on the circles and trim.

Done?

Two hours later I still can't get two of them to align with the -45Z plane.

I've tried creating 'axis thru 2-planes' for the arc centers to align with, which works for the axis I can see, but there's that one axis that doesn't show - keep getting the 'select other geometry' thing when I go looking for it.

How should I be making that octagon ?

Hi,

Please show the process in a screencast and share the file.

Starting with basic issue - no attempt at octagon - just try to see that axis first.

This is a bug. Work axes in Fusion can have variable display extents. In this case, the default extents are zero length. As a workaround, you can create a zero offset workplane, make it large, and then the axis will be created with visible extents, which you can then extend further.

Thanks! I made my sketch plane the 'offset by zero from XY' plane, stretched it out to both sides of origin and made the -45 plane with an axis thru those.

But I was a little worried at first - that axis REALLY wants to be zero - it was VERY short - had to zoom in to find the endpoint handles with which to extend it out to look like the others. 🙂

My octagon sketch went smoothly from there, followed my 'imagined' steps exactly - took all of 3 minutes.

Kinda wishing there was a public list of bugs like this.
