Strange Dot on final Footprint ?

Cailloux
Cailloux over 5 years ago

Picture 1 show a Shape created in Allegro PCB Editor 16.6, file LTshape.ssm      The Shape Origin is dead center of the outline 565X400 mils.    This Shape is utilized in the PadStack Editor to create a special Pin for a custom Footprint.
Picture 2 show the PadStack Editor first page with drill size and offset. File  LTshape16.pad         Picture 3 show the PadStack Editor page 2 with that LTshape utilized as the BEGIN LAYER for copper area. Picture 4 show the actual Package (footprint) finished with Outline, padstacks for pin 1,2,4,5 and that special Pin 3 LTshape. Its origin is also dead center, same as LTshape.ssm

Notice the round dot at the bottom of Pin 3. It only appear in the Package drawing, not in the original Picture 1, the actual LTshape.ssm or LTshape.dra

Picture 5 shows that same Footprint in the final board in PCB Editor. That same dot, now pink, is still there and cannot be selected separately. When using the Find Option and selecting each object separately, the only way to select Pin 3 is when Option > Pin is selected. Then I can hover on the dot near Pin 3 and the whole LTshape lights up as pin 3, but not the pink dot. There is absolutely no way I can select that dot as an object. There is no way to know the existence of that dot except by looking at it. Cannot be deleted, cannot be selected, can only be invisible if I use the Color Visibility manager and disable all 4 layers, TOP GND VCC BOTTOM. If I turn On TOP then the dot becomes pink. With GND On the dot is green, VCC On will get a Red dot, BOTTOM On will not show the dot but Pin 3 turn On since LTshape is the actual Net connected. This Net is not GND nor VCC, it is N357726.

Where is this dot coming from and why is it not a selectable object ? Why can I not delete it ?

    It could be a cline or cline segment on the top layer of the board (Assuming top layer is pink)

    The colour should give you an indication of what layer it is on. Try turning layers off to see. If you are seeing it on the actual symbol then something is there. If you can zip up the final symbol with dra & ssm I can look at it for you.

    All the best.

    Thank you excellon1 : I have uploaded all pertinent files on a shared Google Drive Folder. Have a look. I am very curious about your findings. By the way, I already tried your suggestions, as stated in my original post. There is no way I can select that dot. Let me know if any other fiels are missing.
