Cannot multitransform nor mirror a feature

[Matael]

Hi all!

I failed to use the multitransform tool on the last pocket to apply it to each arm.

Does anyone have an idea why? and how to fix it?

thank's all!

I found some issues but it still doesn't mirror, because I had some follow-up errors. You should check the other sketches for similar issues.

A recompute shows issues with Sketch014. The symmetry + horizontal constraint is overconstraint. This is a known issue, that the solver does not always detect it. You must avoid it "manually". PLease check all your sketches for this. If you are unsure: delete the symmetry constraint. If the number of degrees of freedom (DOF) increases by 2 it's ok. If number of DOFs increases only by one, then fix it.

Furthermore you should use the horizontal distance for horizontal lines and not the general distance; the same holds for vertical constraints. Don't use more external references than necessary.

It is better to use the simplest constraint possible: use horizontal instead of parallel to the X-axis.

You should fully constrain your sketches.

Ok, I will have a look at this, thank's !

Is there a way to disable horizontal and vertical auto constraint?

[Matael]

Here is the file with your suggestions

I think I succeed to remove all symetric/horizontal constraints redundancies.

Every sketch should be fully constraints too now

But I still can't make a mirror/multitransform.

More, If I edit Skecth016, linked to "amincissement_bras" and I tried to rotate the view, it flicker/hide some pieces (but it could be only on my computer) and I have this message :

Code: Select all

Coin warning in SbDPViewVolume::getMatrices(): invalid frustum

same result with

Hi!

I found what was wrong : you cannot mirror a pocket with several objetc if you select "To first" or "up to face" as type.

How to reproduce :
-download the file
-try to make a mirror using a plane as reference
-It will be noticed that :

Code: Select all

Transformation succeded

but nothing appears
-change pocket type to "up to face"
-It will be noticed that :

Code: Select all

Transformation succeded

but nothing appears


How to "solve" :
Select "through all" or "dimensions" or "two dimensions" for the pocket type and it will be ok

I didn't saw it in the bug tracker. Should I make a ticket?

Good to hear you got it sorted

It would be good if you can build a very simple model which shows the same issue. Then it would be easier to see what kind of issue it is.

I already did it, cf my previous post and the mirror_pocket_bug.fcstd (a simple square pad with one pocket of 2 circles)

Sorry, I didn't open it I had thought it was the huge example from before. I will have a look later.
