I've seen this question asked a few times before, but I still need some help. Basically, I want to put my company's logo on my PCBs. Sometimes, I want the logo to be on one of the silkscreen layers, other times, I want it to be on one of the copper layers. I've used other layout software where this was a super-simple task, but not so with OrCAD PCB Designer.
(ARE YOU LISTENING, CADENCE/ORCAD? MAKE THIS EASIER AND/OR MORE INTUITIVE TO DO! IF CHEAP $800 SOFTWARE CAN IMPORT A JPEG WITH ONE MOUSE CLICK, WHY CAN'T YOU?)
Anyway, I digress. What I've managed to do so far is convert the company logo to a DXF using another piece of software. I can import the DXF to any layer I want using the FILE>IMPORT>DXF commands from the upper menu. Here's where the problem comes in - If I try to do this in an existing design, OrCAD erases the entire design and replaces it with the logo. I've read the HELP files about importing a DXF into an existing design using the dxf2a command, but I can't get this to do anything other than to beep at me incessantly and give me error messages that I don't understand. I've seen other posts about SKILL files that can create/import the logo for me, but I haven't been able to get any of those things to work, either. Apparently, I need to be a computer programmer to get the dxf2a command or any of the SKILL files to work, so I'm screwed.
So, does anybody have a method to import a dxf SUCCESSFULLY into an existing design that I can understand? I'm pretty well frustrated with this at this point. It seems to me that there are so many little secret, hidden features to OrCAD that aren't documented, or documented in such a way as to insure that no human being could use those features. Just last week, I had to have a 45 minute conversation with tech support about how to imbed two vias in a ground slug on a voltage regulator chip. This week, I'm trying to figure out the logo thing.
Sorry for the rant. I just don't think it should be this difficult. Why can't they just have an IMPORT>IMAGE option with, oh, I don't know, maybe an "ADD TO EXISTING DESIGN" or "CREATE NEW DESIGN" button?
What OldMouldy means by Dummy layer is a layer that is not normally used. You could use somrthing like BOARD GEOMETRY / ASSEMBLY NOTES or ASSEMBLY DETAIL or create a new subclass (Setup -Subclasses, create a new layer called DXF). Once the DXF is in you can then copy / move / compose / etc to the required layer.
