We seem to be having a problem transforming a folder from PDT to a stereo lith file and the error reads, 'Can't create STL file because of invalid geometry' Do you know why this might occur?

Is there any way to colour a shape on the program so that it will not take the material out when put on the 4th axis? We have shaded in the text and need to do the same with some shapes to keep these at the required hieght and take away the white areas, is this possible?

Thanks for this we have Quick Cam 2d Design which is why the instructions were no use. Does this mean that we can't wrap a rectangular design around a cylinder to create a profile on the surface?

We have designed some font to be placed on a cylinder and are following the instructions at the back of the Denford booklet, supplied on a recent training provided by Peter. However, it mentions on page 40 to create a CNC file we have to select 'Plot' only plot doesn't seem to exist, can you help?
