Adjustable part array problem...

Adjustable part array problem...

Adjustable part array problem...

(OP)
Hi,

I'm trying, and failing, to get how I think an arrayed adjustable part should work.

Here's what I'm trying:

Part 1 - a cube with a four round pockets, big enough for Part 2 on one surface
Part 2 - an adjustable (part) spring (x4)
Part 3 - a cube

So the four springs sit in the pockets in Part 1. Parts 1 and 3 are spaced apart by a variable. The length of Part 2 adjusts to suit.

The first spring is arrayed within the assembly model using a sketch pattern, to create the four springs.

All works well for the un-adjusted part. When the variable is changed the original spring changes to suit, but the other 3 arrayed items do not. I've tried update part etc, but with no luck.

Any thought? I've asked Cutting Edge, our support people and they cannot work it out...

Cheers,

M

Hi,

SE Assembly cannot handle 'dynamic instancing' within Assembly Patterns
in the way you require. Still so in V19, V20???

Damn... that knid of screws things up for us here. The above was just a simplified version of what we do, which is a 90 odd springs...

Thanks for helping though!

The above problem was submitted to Cutting Edge Solutions, who passed it onto SE. They have returned saying it is a valid enhancement request. Which is good :)

I don't like the long way round on anything but how long would it really take to position 90 some odd springs on your part 1 if they were treated separately?  After you place the first spring you can capture its constraints and use them to position the rest.  .... 1-1/2 hours later ... You can then use the assembly variable table to control the spring length as a function of the part 3.

1-1/2 hours! There are further details that I withheld for ease of explanation... Namely these 'springs' are Omega shaped and arranged in a circle, to create a bellows effect between the two outer parts. These parts need to be adjustable (in the model) from the main part so the main part can be manufactured. As we have to many arrangements that need to be modelled, the manual placing will take too long, so until the feature is included, we're gonna fudge it.
