SolidWorks Pattern Equation Help

[JEREMER]

I am trying to make an equation to drive a quantity of a pattern so I can just adjust a qty and then the height will modify accordingly. Is there any way to use an equation for a qty of a pattern? Help is appriciated.

Thanks,

Do you mean the "height" of the part or ????

What type of pattern? (Linear Sketch Step & Repeat, Feature Pattern or Component Pattern)

Just a linear pattern. I basically just want want to set the pattern qty value with an equation.

Here is what a basic one could look like:
Double-click the pattern in the assembly tree, and rename the quantity to Pattern Quantity, and rename the distance value to Vertical Quantity (this is assuming the pattern axis is horizontal)

"VQ"= 16 ' Vertical Quantity
"PD"= 4 ' Pattern Distance
"Pattern Distance@LocalLPattern1" = "PD"
"Pattern Quantity@LocalLPattern1" = "VQ" + 1
"Length@Extrude-Thin1@Vertical Tube.Part" = "VQ"*"PD"+1

The last equation is the dimension entity of the part.

Note the last number "1" on the last equation is the width of the part being patterned, in this case a 1" square tube.

The fun part is when you start using the "IF" and Integer functions.

Hmm... Well, I can't change the quantity or distance values of the pattern to anything other then a number. So unfortunately that seems to be limiting me to what I can do. Please let me know if I am doing something wrong or what else I can do.

Thanks,

Double click the pattern in the Feature Manager.
RMB click on the QTY value, select Properties.
Type a name in the Name box & click OK.

Obviously all other dimensions can also be named the same way.

CorBlimeyLimey,

MERRY CHRISTMAS to you too! And, to all others also!

Is it a sketch pattern or feature pattern?

If it's a sketch pattern you cannot control it because the dimensions will not show up - been like this since SW04, SW05 and SW06

Turn it into a feature pattern then you can control it.

Got it to work. Thanks again everyone.

Not exactly sure if you were talking about a pattern in a part file or an assembly file. You got it working whatever it was, but here is what I was talking about. Mooload didn't like my file, not sure if it was because it was zipped or what, so here is a different location:

(pattern_driven_assembly.zip)

In the assembly equation change the value of VQ to change the length of the horizontal tube.

"VQ"= 12 ' Vertical Quantity
"PD"= 5 ' Pattern Distance
"Pattern Distance@LocalLPattern1" = "PD"
"Pattern Quantity@LocalLPattern1" = "VQ"
"Length@Extrude-Thin1@Horizontal Tube.Part" = "VQ"*"PD"-"PD"+1

Would not this have been easier with a DESIGN TABLE?
