Hi

I thought i would add an update as to the draw cabinet i have been working on

Its working but still needs some tweeks
I have not yet allowed for any 3mm gaps between draw fronts,
and the other more major prob is that........

I would like the draw fronts to be adjustable by user imput but

say the cabinet has 3 draws and the used wants the bottom draw to be 500mm high i want to be able to get the other two draws to divide the left over space equaly

Any ideas on how to do this easily would be great

I have attached the a model of the draw unit im working on
and also some pics Drawers 1.jpg Drawers 2.jpg

Yeah, here's a quick idea.

So the user can change the height of the bottom drawer. And you know what the total height of the unit is. Lets assign some values. Say the Unit is 1 meter tall. And the bottom drawer is 500mm tall. You have 500mm left for the 2 drawers. So their height should equal 250mm each. This is how to set that up mathematically:

LenZ=(Cabinet!LenZ-LowerDrawer!LenZ)/2

That resolves down to:

LenZ=(1000mm-500mm)/2 which equals 250mm.

So that is how you would set the LenZ for the 2 drawers. Whatever the bottom drawer is set at, the 2 drawers will split the difference.

Hope that gives you a starting point.

This modified version puts gaps between drawers, but not on the top drawer. I didn't make the drawers equal heights, the top drawer is taller by the gap.

Modified to not put gap on top drawer.

Hi

Thanks all for your help i worked last night on it and sorted the 3mm gap issue as below

(box height) - (top gap) - (3mm gaps (this number changes depending on how many draws there are)) /(the number of draws)

code :

"=IF(STD_DW_CAB!DRAW_QTY=1,STD_DW_CAB!LenZ-STD_DW_CAB!DOOR_T_GP,IF(STD_DW_CAB!DRAW_QTY=2,(STD_DW_CAB!LenZ-DRAW 1!DOOR_T_GP-0.3)/2,IF(STD_DW_CAB!DRAW_QTY=3,(STD_DW_CAB!LenZ-DRAW 1!DOOR_T_GP-0.6)/3,IF(STD_DW_CAB!DRAW_QTY=4,(STD_DW_CAB!LenZ-DRAW 1!DOOR_T_GP-0.9)/4,IF(STD_DW_CAB!DRAW_QTY=5,(STD_DW_CAB!LenZ-DRAW 1!DOOR_T_GP-1.2)/5,0)))))"

This is for the bottom draw so it has to work and have different heights for 1,2,3,4 & 5 draws

Chris

That code you suggested to use i will have to fit into the code above
so that will be the difficult part
i will work on that soon..........

James Fraser

Isn't that code just:

=(STD_DW_CAB!LenZ-DRAW 1!DOOR_T_GP-(0.3*(STD_DW_CAB!DRAW_QTY-1)))/STD_DW_CAB!DRAW_QTY

?

I may have missed something, but if I am right I think it would be considerably easier dealing with an equation like that than the huge number of IF statements. Much easier to make changes, too.

And I think the top equation simplifies to:

=(STD_CABINET!LenZ-STD_CABINET!CARCASS_MAT)/(STD_CABINET!SHF_QTY+1)

Is this right? Does it help at all?

Hi James

thanks heaps i will try that when i get back to work tomorrow
and thats exactly what i was after a simple way to do it
so much less confusing ...... yaaay
i will post back tomorrow to let you now how it goes

on a slighty different note if i have the following

a draw bottom thats inside a draw
& the draw is in a draw box
& the draw is in a cabinet

how can i get the draw bottom to read a parameter on the draw box

to sum up i would like to now the chain of comand in order to refer back to other componets ?

but again thanks james and all that have helped

James Fraser

Happy to help

Because a component can only read an attribute from its parent, a sibling or a child, if you want to read an attribute more levels away than that you have to have something to pass the message along.

Generally I just use a custom attribute on the levels in between, which is defined as a direct copy of the attribute you are after.

For example, if your drawer bottom needed to know LenX for the cabinet, I would do it as follows:

Cabinet:
LenX

Drawer:
cabDepth=parent!LenX

Drawer_Bottom
attr=parent!cabDepth

I use things like that to pass the message along the line, cabDepth could be called whatever you want and you could use Cabinet! and Drawer! in place of the parent! bits, but I like using parent.

I hope that makes sense.

Could it really be that silly?
that there is no way to call an attibute from a parents parent (grandparent! )?
a string equal to the file path version of ../ would make life so much easier.

Chris Fullmer

Yes, that could make sense to do that. At this point though, you have to pass it through each level manually
