Equation Referencing a component pattern?
Equation Referencing a component pattern?
(OP)
hello,
I have built an assembly of guarding using box section and inch mesh(horizontal & vertical bars).
I have created an equation in the assembly between the top length of SHS and horizontal bar of the inch mesh so when I change the length of the SHS the bar length changes accordingly.
The vertical bar of the inch mesh is always at a constant length so no changes need to be made. I have used the pattern feature to distance the bars accordingly. Is it possible to create an equation relative to the component pattern that would place so many vertical bars at 1” apart according to the length of SHS?
Picture below shows standard panel.

Picture below shows modified panel.

Thanks,
Callum

RE: Equation Referencing a component pattern?
You could then link this to an equation.
It could be something like:
Horizontal tube = 24
the pattern number would be something like
24-1

hmmm - i have tried driving this change via an equation to change the number of linear patterns depending on the length of shs....sadly I cant get this work.
Basically I want the number of linear patterns to change with regards to length of top shs. I.E. the narrower the panel then the fewer horizontal bars required.
The ideal set-up is so that I only have to change the top SHS length and the full model will update accordingly, i.e. the followig are updated:
1.the length of middle SHS,
2.the length of bottom SHS,
3.the length of horizontal bars,
4.the number of vertical bars.
I have managed the first three problems but the forth is beyond me!
Anyone?

The Equation would look something like this:
#_of_bars = int((total_length-2*space_on_end) / spacing)+1
The int() function rounds the results of the division to the lowest common whole number (difficult to have 10.33 as a # of instances).
Depending on how you place your first instance in the pattern, you will also need another equation to center the entire pattern in your frame.
If you wish, let me know and I will see if I can create an example you can download and see.

That would be great if you could upload an example for me to see - much appricated. Unfortunetly I have basic knowledge of the equation maker - still learning!

Tried it again....worked a treat - thanks!
I have rewarded you with a star :O)
