ifeatures and adaptivity

[PACDrafting]

Not sure why this is an issue.

When placing an ifeature in and projecting geometry from another part which makes the ifeature adaptive. Why can't you create a feature e.g. extrusion of the ifeature? You can't even make the ifeature unadaptive.

Hi! There is an implicit rule in Inventor blocking an adaptive sketch from being shared. This restriction is in place to avoid collision of two driving forces.

Let's assume it would work. Feature1 is adaptive due to Adaptive Sketch1 and Feature2 is adaptive also due to Adaptive Sketch1. If the part is in an assembly, you can use one set of assembly constraints to drive Feature1 and another set of assembly constraints to drive Feature2. However, the deformations required in either case here both point back to Adaptive Sketch1. This will be a collision of forces.

In some special cases, adaptive sketch could be shareable without running into collision. However, the case is too rare to make it a norm. As a result, adaptive sketch is blocked from being shared.

Thanks!

OK thanks makes sense.

However, might be an idea to not allow an ifeature to become adaptive.

You cannot turn adaptivity off to enter into feature mode. you actually need to delete and reinsert the ifeature to work.

Thanks for your reply.
