You can add text to the bottom layer as copper. Be careful and make sure you run Clearance check after you added text as copper. Otherwise you may unintentionally short some traces.
Make bottom layer active and select Drafting Tool bar. In Drafting Tool bar select Text icon (looks like 'ab'). In Add Free Text dialog type in the Ref. Des. text and make sure you check 'Mirrored' box.
Yan - Thanks for replying so quickly!
Andreas - Good suggestion! I will move this conversation to the PADS Layout community.
So I need to add each "TP1, TP2, ... TP147" individually by writting a simple text on Bottom Layer? But is there any automatic function which allows me not to write all 147 text parts by hand?
select all test point go to property label new and you create oone new attribute (refdes)
in your layer preferred .
try to create a new attribute refdes.
Select all testpoint goto properties -label - news .
in the window (add new part label) select the new layer for refdes.
The problem is that all of the components on the bottom layer already have their labels with Ref. Des. on this layer. But I do not need to have all these labels printed in copper. I need only for test points. So if I choose Ref. Des. in CAM output for Bottom layer, then ALL the label will be printed there and it is a problem because some of them (not for test points) will make connection between unrelated traces, as all of it will be copper. If I would delete unrelated labels, that would be a solution. But I do not what to completely delete them. So I see only one possibility, to write TEXT in copper for each of the test point individually and in CAM output I will not choose Ref. Des. for Bottom layer. What do you think?
One attribute can have many labels. So the RefDes attribute can have one label for silkscreen, and in your case, a second for the solder side. To make it easy to output them in CAM, place all of the existing ref des labels on their appropriate silkscreen layer, and put the new ones for your testpoints on the solder layer. Use the Filter and Find tools to do these as a group. Adjust your CAM documents accordingly.
ETA: I reread your first post. You can leave the existing Ref Des labels as they are. But you will have to manually inspect for shorts since these will be output in copper. On the other hand, if you placed all these as text, you could use DRC, but it would report a lot of false errors, since it doesn't check the strokes, but the text bounding box, and you would have to manually check everything anyways.
Thank you very much! Now I got it!!!
