Shape disappering after changing constraints

There may be overlapping shapes, a couple of things to try, turn off all colours and turn on just the boundary for the etch layer in question, just seeing the boundary might help. Check the Status for unassigned shapes, if there are any, run an Unassigned shapes report, this will list the unassigned shapes and locations, try picking the shape and moving it off the board, Edit>Move, Find to Shapes, pick shape, in the command window, "ix <some_amount>", or "iy <some_amount>", and enter, "<some_amount>" should be enough to move the shape off the board and memorable enough to use it as a negative amount to move the shape back. As the shape(s) are moved off the board, turning the etch on may expose the problem, like repeated shapes at the same location. Delete the excess shape(s) and move the shape(s) back, normal service should be resumed after updating the shapes to smooth.

 What is the report for unassigned shapes?  I could not match the description in the help file with what reports are available.

 One other point, I can not select the shapes, when try to pick it, it does not show up, yet it is still in the dynamic shape list.

 This is the output from the shape report:

Shape Settings -------------- Net name P1V2 Class ETCH Subclass PLANE5 Extents (1660.2 951.0) (6012.8 5550.3) Generation Results ------------------ Number of Etch Shapes 0 WARNING: No Etch Shapes Shape Instance Settings ----------------------- Shape fill ---------- 

It does not explain why these etchs are disappearing.

Try the Shape No Net report.

Also try moving the shapes the you CAN see, out of the way, like off the board, that should eventually leave the "disappeared" shape. You should be able to work with the shape boundaries whatever.

And what happens if you change the contraints back?

It may be unlikely that forum contributors making "blind guesses" are going to chance on the cause of this, you may need to submit the board through the normal support channels for someone to take a look at the actual data.
