Creating a formula for number of convolutions in a shaft?
Creating a formula for number of convolutions in a shaft?
(OP)
Hello,
I've seen it done before, but how would I go about creating a formula for generating the number of convolutions (bellows) in a sketch?
I know how to create a formula ,but when you have a profile and you want to shaft it around an axis, I'm having difficulty in using parameters and formulas to generate how many profiles to shaft.
Say I want one convolution, I would type 1 in the parameters, typing three would generate three convolutions, and it would automatically update the number of convolutions in the sketch.


Thank you for any help

create a GSD rect patterne instance & spacing(linked to value in sketch)
create a join of the sketch + the pattern
create a parameter as integer with value limit(low = 1, high is what you want)
drive the pattern instances with parameter
now we see that if parameter = 1 then the pattern and the join go bad. we will fix soon KWA rules
now create a parameter Curve
create KWA rule and make it as follow:
if parameter = 1
(
deactivate pattern & join
)
else
(
activate pattern & join
)
create another rule as follow:
assign curve = sketch
if pattern.activity = true
{
curve = join
}
verify that curve is what you want when you change parameter
finish with revolve Thick Profile based on curve
