Assembly3 - Aluminium extruded parts

[Medestrac]

Hi,

I'm doing an assembly of a rectangular frame made of aluminium profile. There is two "length" parts, and two "width" parts.
I have a sketch of the shape of the aluminium, and I extrude this sketch to get my part.
I save one file with a 500mm extrusion ("width"), and one with 1000mm extrusion ("length")

I create an assembly in Assembly3, link my 2 parts, put element count to 2, create the constraints...etc...

Is it possible to only link a "basis" part in the assembly, and then change the length in a parametric way in the assembly? For example get a spreadsheet with length/width to resize my assembly?

if you mean the approximate structure as in Figure 1, it can be implemented without Asm3.
I has one body for extruded profile with length, defined in SpreadSheet. Then for this Body ("Профиль80х80") I create LinearPattern.
Also in Spreadsheet you must define some variables (In my situation I use External Spreadsheet file, named "ТаблицаПараметров")
There are (in my situation, names sometimes it russian translit)
1. NumberProfileBody (Number of profile body, on picture it equal 5)
2. RazmerProfilja (This is width of profile. In my situation it = 80mm)
3. GlubinaStanunu (This is NumberProfileBody miltiply RazmerProfilja)
and 4. ProfileLength (Length of 1 profile) You can insert this value to expression for extrusion length.

Could this help you ?
It is a question of seeing on an example how from a single Body object and a SpreadSheet calculation page one can build an assembly containing different variants of the base object :

Here is the page that is supposed to host my video, but at the moment the server seems to have a problem :

So in the meantime, here's another link, but freeze frames don't work in this format :

Edit : the server works correctly !

Yes! Thanks Jean-Pierre, that's exactly what I was looking for!
