Dimensions change unexpectedly when updating parameters

aidan.hurleySRXFP — Fri, 13 Jan 2023 16:13:10 GMT

I'm working on a phone case that uses parameters to switch between different phone versions. I'm using the Parameter I/O plugin to store the dimensions of each phone in CSV files. Importing a CSV file updates all of the parameters to fit the relevant phone version.

I'm having a problem where when I update the parameters, some dimensions that are not in the parameter list will change to arbitrary values.

Fig. 1: The dimensions reference another body, and define a clearance around it.

Fig. 2: After updating to a different parameter set, the dimensions change. They leave the sketch lines where they are, and act like driven dimensions.

I've been working with this file for months now, with 8 different parameter sets. This problem only appeared this week, with the addition of 4 new parameter sets. I've been unable to reproduce the error in another file.

Unfortunately this project is NDA 😞 I tried reproducing the problem in a file I could upload, but I couldn't get it to happen again.

I've also just found that it's deleting dimensions that I've recently added
