are used custom sw cad for corel draw, correct?
no, there is an internal converter with the possibility of extensions for other features; per minute 0.50 of the first video see the importable cad 3d formats directly.
in the past I have realized most technical catalogs for different
Italian companies and not of the power transmissions industry using coreldraw (from version 4 to 18) in the two-dimensional field in combination with corel vein (programming but not available) and indesign, but then I imported and processed the 2d (dwg). the equivalent of illustrator, which I have but not use, is coreldraw but, while the first is very strong in graphic illustration, coreldraw is particularly strong in the use of graphics in the technical field having functionality, even programming, to manage dynamic links between excel archives and coreldraw.
this catalogue with dimensions in mm, it was also made in the American version with inch dimensions; this was possible using automatic coreldraw features that allowed you to convert all dimensional values of the designs in a few minutes with zero errors; with illustrator, manually, it would take several days and extensive controls.
see also this other example.
coreldraw use it now to create multi-level dimensional drawings that, through our proprietary configurator assembles the final dimensional illustration design according to the configuration carried out; see pdf attached.
coreldraw technical suite is the evolution of 3d-oriented coreldraw technology; However you can try it for free for 30 days to see if it's your case.
