Confused about fixing missing origin issue

[darkrunes13]

I find myself unable to fix the missing/invalid axis issue with sketch 4 of the attached part. After redefining axes and getting a prompt to specify the origin, the cursor gains a + icon but I can't find anything that I'm able to click on. What am I missing? I'm also unsure what caused the origin to go missing. Information on how to kill an origin would be appreciated so I can avoid doing it in the future. In case it makes a difference, the geometry for Sketch 4 was copied from a different part then the straight lines were adjusted as I couldn't figure out how to get the whole copied section to accept being rotated by 90 degrees.

Thanks

Welcome to the Forum!

Here is the procedure on how to fix those errors:

1. Right-click the sketch and select "edit coordinate system"

2. Select the blue (Z-axis) point and then select a point where you want the origin to be

3. Select either the green (Y-axis) or red (X-axis) arrow and then select the edge to which it should align

4. Right-click and select "flip axis" if needed

Hope this helps.

Thank you so much! I wasn't clicking on the little blue z-axis first which is where I went wrong.

Is it possible to open the design doctor when there are no constraint errors (no red + to click on)? I originally noticed the missing origin error in the design doctor in my assembly when I created a poorly thought out constraint, but once I fixed that I coudn't start design doctor again since no constraints were failing.

Well, the + should be visible in the part.

From the assembly level the only way i can quickly think of is doing a "rebuild all" (on the manage tab).
That rebuilds all the parts and forces the doctor to show errors, but it also causes all the parts to require saving (dirtied).
