Bug report-Joints parametric

[mihail.hornea]

so ever since the last update, the joints feature appear broken in parametric designs, if I multiply via rectangular pattern a component which already has a joint in it. 

So to replicate the bug

I create a new design

In that design I create a number of components -in my case

Frame- (from 2 sheet metal components that are identical but different lengths)

Fins(that are also sheet metal and have a movement pin between them)

I then proceed to assemble my frame from 4 profiles(2 originals and two mirrored)

then I add fins to the design based on requirements

The joints from the first assembly of the frame and the joints from the first 2 fins are Red and i am unable to ix , even if I delete them, new red joints appear. 

Furthermore, in similar designs I have worked on in the past, that were parametric in nature are also broken now in similar fashion, joints are red and broken, and cannot be fixed unless a complete redesign

In the pictures:

Pic1- How it looks like-and should look like yet I cannot move around, even if I unground-insert into another design

Pic2-where/how the frame pieces should fit- again cannot move/ do anything- I tried re-associating the joint or replace it altogether doesn't work

Pic-3 joint done in another design that I inserted into this one and then broke the link in the current design.

Hi,

1. Please share the file (s). and name the parts or features are involved

File > export > save as f3d on local drive  > attach it to the next post.

2. Is there a special reason to use joints (PIC 1)

The design is simple but designed to be changed by someone who is not an engineer, to extract the bill of materials and understand whether or not it can be done. as such they only have to input the length and width in the change parameters function ,(I renamed them for you) and get a result. then they do their job, which I am unfamiliar with. They asked me to do this for most products and after the previous update  I cannot seem to change the parameters without getting a broken joint in any design, yet this is the worst offender. In other designs I was able to redefine the joint and that seems to solve it, but not in this one. Granted I haven't checked every single design. 

Also yesterday I found it funny "floor(200/196)=2" which took me about 10 minutes to identify and then I reinitialize the variable by double clicking on it to edit and and it fixing itself.

also yes there is a point in using joints, as i may use a different pin, and i would rather have it in the fin/ lamela assembly to be able to replace it by updating or change the design further/ do modifications. Right now, i cannot use the history to roll back and add/remove features and leave it before the end, as the design will be broken as shown in pictures. It only" fixes itself" once the history maker is at the end.

Your frame was not working for change of size, 

I have reworked your file, so now it does not break, with change frame size. 

(change of Dist_lamele does make the other side of the frame holes break the file - let you sort that out)

Check that some dimensions have been updated, 

I like you - found that Rigid Groups do not follow the user intent, and used joints before patterns.

Use circular pattern instead of mirror, for BOM workings.

Might help....

Thank you for the solution, however I find it temporary. In this particular case, it works as i have the offset variables that make the frame holes line up and create symmetry, however, that may not always be the case and as such the holes may misalign. That is why I use mirror and cannot use circular pattern in this instance. obviously i can just copy my frame side around to the other side and join it , but i hope i have explained why i may not always and based on my workflow will probably never do that. The products need to be symmetrical in at least one plane and and the best and easiest way to do that is to use mirror. 

Thank you again for your time and let's hope this to be an isolated case
