Parameter Change - Compute Failed - No Target Body

[bprocket]

Noob question.

I created a square tube via an extrusion.  The extrusion length is defined as a parameter.  I then cut a 45 degree angle on one end (like one might do with a saw), and then I cut a square notch in one of the 45 degree edges.  Both of these were done by creating sketches on the tubing faces and extruding again.

When making the tube longer by changing the parameter value I get a compute failed - no target body error. 

My ignorant suspicion is that some part of the component is not properly joined and the parameter cannot be applied as expected.  Attached is a screen grab of the part after increasing the extrusion parameter by 2 inches.  The new length seems to work - sort of.  I expected the new length to be under the feature, but instead it was added above the feature.

Soooo, what am I doing wrong?

Please attach your model so the Forum users can "show" you how to avoid this issue instead of trying to explain it.

If you do not know how to attach your Fusion 360 model follow these easy steps. Open the model in Fusion 360, select the File menu, then Export and save as a F3D or F3Z file to your hard drive. Then use the Attachments section, of a forum post, to attach it.

Drawing attached.

If context helps, I'm planning a lathe stand consisting of two pedestals separated by enough space to put a tool box in between.  Two rectangular frames will be built - one for the top and one for the bottom.  The pedestals will be sandwiched between the two frames.

The notch in the part - a pedestal leg - acts as a place for the frame to fit similar to puzzle pieces.

Sooooo, if there is a better way to accomplish the goal feel free to educate me.

Hi,

This is because the sketch for the section is not bound to the body.
Project the body onto the sketch and create your cutting line in relation to the projection.

Beautiful.  I'll give it a try.  Thank you.
