4 Levels of Grouping

Davidfi1

Hi,
I found that if I use 4 Levels of grouping SketchyPhysics stops working
Is it a known bug / feature?

See attached file.

I suppose it's not supported because it doesn't seem necessary. To fix this, you just have to explode the groups within the group. EDIT: What do you mean it stops working? The group is just treated like a box for me.

Well
The grouping of objects is done with the intent that similar groups could be copied with ease.
So, in the case where you have more the 3 levels of meaningful objects grouped together - SketchyPhysics changes its behavior.
for instance if I do:
Table & chairs - group 1
4 chairs - group 2
4 legs in each chair - group 3
now if you want to put plates on the table - you can not group them to the table.

If you will make another group the hole big group becomes one big box.
Things can not move under the table etc...

I need to explode one of the levels to enable SketchyPhysics normal operation.

Just a little hard to figure out what the plates on the table have to do with the things on the floor under the table

Don't you think?

I see what you mean, but maybe you should just make the parts, and keep a 'spare' of each one. That way, you can create the complex group, then explode the groups within it when they're positioned. If you want to move something, delete the parts and copy the spare, then explode it.

I think about solving this issue with a script.
I could write a script that will
Go though all the second level groups, and
If there is another group inside it - explode it,
And repeat this for all the groups until we only have two levels of groups.

What do you think?
Should I return to the "grouped" state after the simulation stops?

I feel like I'm in too deep I think it'd be a good idea if the groups returned afterwards, as they don't really matter in the simulation. I really don't know any ruby script, so good luck

Its a bug. And one I didnt know of. Thanks David.

Not sure what is causing it but I will fix for SP3.

CPhillips

Turns out this isn't really about group depth. It happens when a group contains only a single group.

Group
  Group
    Box
    Box
    etc.

Ill fix it in SP3.

This problem is not solved as far as I can tell
Thank you.

Chris
Welcome back!
Did you look into solving this in SP3x?
Could I help?
Is there going to be an RC2?

Thank you
David.

I thought I had it fixed but apparently not... I need to setup a bug database so these things dont fall through the cracks.

Davidfi1

Most logical option is to use Google's bug tracking ...

Hi Guys
This bug is still not fixed at SP3 on my computer.

Thank you.
David.

Unfortunately the fix caused other models to break. I'll take another look at it and see if I can come up with something safe.

Davidfi1

Excellent
Thank you.

Could you also fix the reverse face issue? http://forums.sketchucation.com/viewtopic.php?f=61&t=24201#p206890

Hope it is no too complicated.

CPhillips

Its fixed in next version. I hope it doesn't break anything but it was a bad bug and needed to be fixed.

Davidfi1

Exelent thank you.

Good work.
It works like it should
