I have free 2D ST8 and am using Windows 10.
Is it possible to import into the free 2D software, a .pdf file to use as a basis to produce a scalable 2D drawing? I looked at a post referring to Inkscape - the user was obviously an expert with the software (very quick actions) and as the language was not English, it did not help!
You can try using VLC Media Player to slow down the speed of the video.
The non-English version is the best video available for importing PDF into Solid Edge.
I assume all you want is to insert the bitmap as an image. If that is correct then there is a command called Image. Image takes the bitmap and puts it on the drawing as an image(picture).
