This is kind of hard to describe but I'll give it a try and hopefully some of you might understand my situation.
One of the problems I find myself against many times is illustrating machinery, vehicles, buildings (Anything that has straight lines etc.) in PS using a Wacom.
For instance, when I do a freehand machinery illustration (with pencil and paper) I can pretty much get the desired results that I want. One of the reasons I can get a freehand sketch with good straight lines (no rulers) is because I have the freedome of rotating the paper around to accomadate my arm's natural stroke.
However, when Im using a Wacom tablet on PS I dont have the choice of rotating the canvas on the fly.
Now, Ive seen pencil sketches created with a Wacom tablet on PS which have perfectly straight lines but still look like pencil sketches (Meaning they fade near the end of the stroke).
I tried using my pencil style PS brush to create these straight lines by touching the canvas with my Wacom pen , then pressing "SHIFT" and then touching the canvase again with my Wacom pen. I did get a pencil like straight line but it fades way too short. (Jeez, did that make any sense?)
Anyhow, if anyone has an answer to this technique I would much appreciate it.
Also if there are any other tips on creating good machinery, buildings, vehicle (anything with straight lines) illustrations it would be great.
