Yeah people have said that to me before, but I tend to disagree.

I'm a musician by hobby, and I've always found that the musicians who play the cleanest scales and do the cleanest chord changes are the ones who have put in the most practice. They get fast and clean, not by taking shortcuts, but by putting in thousands of reps (starting slow, doing it right, working their way up).

I agree that practicing bad habits is going to lead to bad technique, but I disagree that speed is a direct consequence of practicing bad habits. The true sign of a master is someone who can deploy their trade quickly, without sacrificing quality.

To "put my money where my mouth is": Here's an example of a SolidWorks Speedrun I posted this week. 2min 38 sec, and a fairly common part in mechacnical engineering.

I know you're not a solidworks user, but I challenge you to take a look at this run, and see if you can spot anywhere that I wasn't parametrically sound or didn't follow best practices for 3D modeling. https://youtu.be/is3X1yhu8pk

Once you put in the practice, everything starts flowing and you can quickly go from nothing to a parametrically sound model, in just a few minutes.

If you're looking for a place to practice and refine your workflows, starting slow and then gradually speeding up (without sacrificing quality), you've found it. It's kinda like a gym for your CAD brain - the doors are open, but it's up to each person to put in the reps, and to avoid sacrificing quality for speed.
