Appreciation post: My attempt at a 'quick' 3D model of a porch swing went sideways

I tried using a new parametric modeling plugin to speed things up, but I must have clicked the wrong constraint. The final drawing had the swing's chains going through the seat and the roof beam. Has anyone else had a plugin just completely misinterpret a simple assembly?

Ugh, parametric tools can be so confidently wrong sometimes.

Confidently wrong" is a good way to put it. I see what shane_wilson means about user error, but sometimes the tool itself makes a weird leap. I've had a simple change to a wall height suddenly delete a door because of some hidden rule I forgot about. The software presents that result as totally correct, even when it clearly breaks the design. It follows its logic perfectly, but that logic can be flawed from the start.

Confidently wrong? That's just user error most of the time. If a parametric tool gives a bad result, the rules and inputs were probably set up wrong. They do exactly what you tell them, so the blame usually sits with the person who built the model. What problem did you run into?

yeah but @kelly470 is right, sometimes the software just makes a wild assumption that you didnt ask for. I've had it delete a window because I moved a wall two inches and it decided the window was suddenly "unattached" or whatever. Like no, I just wanted to move the wall, not redo half the model.
