Omega 6.5

when you say PDF are you talking a raster object?

 

If it's a vector (made of lines) PDF, you should be able to import into Omega and cut stencils from it.
Just open a blank "page" in Omega. Click File, Import. Find "PDF as vector" in the drop-down menu "Files of Type" and choose that. Then you have to hit OK a couple times, I think.
When the image shows up on the screen, make sure you have it all selected, then click CTRL and 1 together, then click CTRL and 2 together. That process removes the "fill" from the images and makes the lines cuttable.

If it's a raster (made of pixels) PDF, that's a different story. You're going to have to somehow trace or re-draw the image to create lines that can be cut.

 

PDF can be opened directly. You need to select one of the option on Open dialog box. (Vinil only, for example)
