I have a set of .tif files. Does anyone know of a tool to convert .tif to .dem in a form that OCAD can read?
You can do that in QGIS, a free opensource programme: https://www.qgis.org/en/site/
Here are some instructions: https://gis.stackexchange.com/questions/31827/open...
I use tif files in OCAD all the time.
Warmly recommend using QGIS for all conversion stuff
