3D sketch - issues with dimensions and constraints (since latest F360 updates)

[davideemilio.marazza]

Since the latest Fusion updates (Oct/Nov) it seems sketch 3D is going south...

1) There are issues with the the shown dimensions while editing the sketch. If a dimension is clicked to e.g. amend the value but the dimension sits on a different plane it disappears forever from the sketch...

2) Constrains do not work properly. Appling (actually rather simple) constraints into a 3D Sketch actually makes it behave to "can't compute" as it is behaving like it is over-constrained but it's not. This makes parametric design a dead end with 3d sketch

To test it out try the first build of this Icosaedro model

and it'll get overconstrained at once... was not like this before

Hi,

I recommend watching tutorials that describe other procedures.
For example, This one  by @KristianLaholm

While this might solve the specific case (i have not tried that yet) still does not answer to the point that 3D sketch does not work as it should... and does not allow a parametric workflow in most of the use cases (not to mention again the fact that dimensions get lost in the multiverse...)
IMHO it requires a lot of debugging / coding still...

Can you share your design?

sure thing (and thanks)

Here it is

can't alter neither the angle nor L (which is segment length) while i shall be able to
