line based components snapping undesireably

Please look at the attached file and see if you can give advice as to how I can control line based families so that they will not snap or meet the way I want them. The snap at corners and when they get close to each other. Part of it I manage to solve through parameters after snapping but not all of it. When I fix one end the other one moves. It becomes a cat and mouse non stop chase...

Any ideas?

 

Thanks

I can immediately see that there is a constraint conflict between two or more geometries in the family. I would troubleshoot by flexing everything in the family until it broke. I'm not up to that time-consuming task - which is made doubly difficult for me because of the different language. It's like driving a car in a foreign country: everything is familiar - and unfamiliar - at the same time. HA !

@FinearcLtd hi

 

Apart from locking the label of a couple of elements/ref planes in both head and jambs (for the the aluminum track)... It flexs fine in the editor... I tried to twist and turn it and it didn't break and it places fine...it functions just as a line based should or supposed to. You added the track offset (Instance parameter) at the ends so one assumes that it is how you want to control it (logical)...So I am kinda not sure where the issue is (see screencast)

 

Can you maybe elaborate a bit  on

  1. what you mean by "or meet the way I want them." (a sketch or a screencast might help understand better what you would like to change)
  2. Both ends of the family seem to snap fine and when draging one end the otherone stays put! so I am also not sure about what is meant by the cat and mouse chase
  3. If there is a specific point which I missed...where the family breaks please highlight it or tell which min:sec can it be seen

...if it is the corner issue where you strech it to the end point of the track but it snaps back to its original place creating this gap...then you have to re-align the familiy in the editor. At the moment the line is somewhere between the Track and the Palroof...you need to set the line to be aligned with the faces of the profile which you want to meet between two adjacent element ... example align to the outer face of the track or the inner ,,,, keeping in mind that snap point is the end of the line (placement point) ...having the face of the profile aligned to the line might give you a cleaner joint

Thank you R.D.

I am not just refering to the corner issue, which you experienced in you screecast. The autojoining of the elements does seem to be unstable, believe me. I have been working on this thing for a couple of days now in a large facade. I found a workaround, making the length of the line equal a type parameter which allows me to stablize the sizes. However, without it, snapping one end moves the other. I don't need the elements joined. I need them 1cm apart and the autojoining interfers with that. I now know that I sould have used the generic family by face to have better control. The autojoining in the line family is basically unneeded and unwanted.

 

Thanks

Did you try to place it without the CHAIN option checked? It might give u better control over it

cool family :leicht_lächelndes_Gesicht: though

Chain option has no effect on the snapping behavior.

 

It is 2018 and this has been a known issue since 2011.  Autodesk, any plans to introduce a fix for this issue? 

We need a bug fix to be able to turn off the auto join for line based components.  Control could be similar to wall families where one can right click and turn off the ability of a control point to join.
