OK, NVM... I just found the "Make Unique" right-click option.

This has solved my particular issue

Just saw this thread as I'm experiencing similar issues with the attributes of copied components being 'linked'.

I don't see a general resolution (in the above thread) of the issue or info forthcoming about which attributes are 'instance-bound' and which are 'definition-bound'.

FWIW I'm trying to change the material attribute of each child copy independently, based on certain value of a parent attribute. Each child has a formula + if statement as the material attribute. If I adjust the formula of one copy's material attribute it propagates to all of them.

Is there a way to make the material an instance-bound attribute or else can anyone suggest a script workaround where the parent can set the material of each child independently?

TIA,
Chris.

Thx for all yr help Xrok1.

Your suggestions are all good. The hidden lines occurred to me also between when I posted & saw your reply.

The way I see it I've got a couple of options, but I'm liking the idea of the two different hole spacings as sub-components...

Look out for the finished version in the 3D warehouse!

Cheers,
Chris.

Thanks for the reply!

OK, I started again and attached is the latest incarnation. It's close, but it'd be good to get rid of the joins between copies.

Note that the hole spacing is not uniform - according to the spec for 19" racks, they have to be spaced as shown.

My initial idea was that the base rail (with no holes) could just scale and the holes would be repeated with the hope that they'd "punch" through the rail material

Ultimately it would be good to be able to scale the component so it truncates at the midpoint between any pair of holes - pipe dream perhaps?

Cheers,
Chris.

Hi All,

Firstly: noob warning

Hope I'm not belabouring a previous topic. My searches & browsing of this list didn't show anything I could recognise as similar to what I'm trying to do...

Attached is my work-in-progress - a so-called Z-rail for computer racks which is intended to scale in the Z direction and include the holes.

The issue is that the outlines of the holes appear, but the internal faces won't automatically disappear. The hole component has the 'cutout' attribute set, but I suspect this only works on a single face whereas I need it to 'push though' to both sides of the base rail when it's drawn.

I've seen the orthogonal-push method in the Ruby API but I'm not sure how to go about connecting-to/triggering it from the DC.

Any advice appreciated.
Chris.
