Change Model Accuracy in Bulk mode

[Kishore_K]

Hi,

Is it possible to set the model accuracy of all components in an assembly to "Absolute" at once?

I tried creating a mapkey, but it requires opening each part one by one, which is a tedious task. Any tips would be appreciated.

Custom program or ModelCheck to do that sort of bulk change.

I've always used a mapkey.

The danger of trying to do this in a batch fashion is that, in my unfortunate experience, sometimes switching the accuracy to absolute when the modeling has been done in relative accuracy can result in a failure of the model when it attempts to regenerate. Relative accuracy allows a variety of sloppy results to persist; it is more forgiving of poor modeling.

Anything with an import or inheritance is more likely to fail with a change to absolute accuracy.

[KenFarley]

Yeah, and many times models that have multiple surfaces with interfacing rounds will change topology, like number of surfaces to handle a transition, and cause a lot of dependent features that use those surfaces to fail. Where you scratch your head and decide, hmmm, maybe I'll deal with this after another coffee.

I even tried using a mapkey, but it requires opening each part one by one. I also attempted to create a mapkey to activate each part and change the accuracy in assembly mode, but unfortunately, it's not possible to change the model accuracy of an activated part directly within the assembly. How did you manage to achieve this using mapkey?

[KenFarley]

I change the accuracy of each part one by one, particularly for the reasons I stated. For simple parts, it might go along nicely, but more complicated parts, parts that are from imports, etc. there is a good chance that failures will occur. Parts that were built with relative accuracy are more forgiving of modeling sloppiness.

If you insist on trying to bulk change a bunch of models, I'd either look into batch processing or using a trail file, both topics that have been discussed a lot in the past on these forums.

Hi,

if you are accustomed with creating of trail files then you can generate trail file which opens all parts and subassemplies one by one into separate window and changes their accuracy.
