sorry, but i have to disagree with that.
i might not be the best 3d modeler out there, but i doubt i am the worst and 3d modeling is just a side job that i hardly put any time in.
for my actual job, the job of a landscape architect, i needed to master Autocad and Photoshop, and considering my boss has not fired me yet, i suppose i am doing pretty well. i also work with other graphic programs like illustrator, in design, gis, blender, etc
and i can tell you, i can't draw, and i can not do it even if my life depended on in.
Not for my lack of trying mind you. But especially for a landscape architect, my drawing skills are horrible. You don't need to be able to draw with a pencil to use graphic computer programs, all you need is to understand reality and how things like perspective, shading and scale work.
Leaning to draw can help with all of those things, but it is not the only way to do it, learning to make photographs like a professional also teaches you a lot of the basics. And i personally find that observing and studying reality and the stuf you wan't to 3d model a lot more useful that learning to draw.
so if you like drawing, do it!!
it might help a lot in developing your computer skills. But saying you can't go beyond the basics of 3d modeling if you can't draw is just nonsens.
