Why I use AutoCAD instead of QCAD
July 26, 2011Posted by on
A couple of reasons, really. Number one on the list, though, is that QCAD is useless with my drafting style. Let me preach on it.
In AutoCAD, one can simply hit ‘l’ (or ‘L’, but the extra keystroke is not necessary) on the keyboard to draw a line. No clicking in the text box at the bottom is necessary. This makes drawing lines very fast. In QCAD, one has to click on the text box at the bottom, which is very frustrating. The alternative is, like in AutoCAD, to click on the little icon in the toolbar. But wait, rather than then being able to immediately draw a line, one is presented with choices for a bunch of different lines. When it comes down to it, AutoCAD has the same choices, but they all get their own separate icons. It’s just one click, and boom, lines can be drawn.
But wait, it doesn’t end there! When one is done drawing the line(s), one cannot simply hit <Enter> a couple of times and get out of line drawing. It has to be manually done by the little icons on the left hand side.
Then, we get to splines. I use splines probably more than lines when drawing ships. I’ll trace out the stations of a ship with splines, arrange them three dimensionally along the profile, draw in the water lines (which are also splines) and fair everything out to get a nice, smooth hull. Well, since in QCAD all the points in the splines must snap to existing entities, it makes it difficult to trace things out.
Looking around in QCAD, it isn’t bad feature-wise for a 2D drafting program, and has come a long way since the last time I mucked about with it. However, the user interface does not present itself very well for a professional draftsman (which definition I fit, even if in the current economy that’s not how I make my living). For non-professional home/hobby use, it can be made to work, but I wouldn’t even think about doing some of the the things that I do with AutoCAD with it, even 2D (and considering I do the majority of my drafting three dimensionally…).
You know, it’s odd that a Free Software supporter such as myself would choose the proprietary software over the open source. However, in this instance, the open source program just doesn’t cut it. QCAD is probably about twelve years or so behind AutoCAD in terms of development. Sounds like I’ve just given myself a new project…
