I have been trying to use both composer and just the 3d PDF print in solidworks 2016 but every time I output the document it is blank.
When I try to use composer it cannot open any solidworks drawings or assemblies it just gives the error shown in the attached image.
So instead I tried to use the print 3D PDF function - attached image 3D Print PDF 1 shows the selections I have ticked on the "save as" dialog.
When I do this it opens a completely blank document with no content at all.
So I tried to use the "Publish to 3D PDF" option under Solidworks MBD (options shown in Publish 3D PDF) - the result if output with no models at all (shown in publish output image attached)
I am not sure if there is something I am not doing correctly or not, every video I have watched seems to show the steps I have taken as working.
