Parameter Syntax

[Anonymous]

Quick question:

Is the following legal syntax?

((PI * (OD - Thickness)) / 360) * (d18 * 2)

When I type it into the parameters, it stays red.

Where.......
OD is a User Parameter and set to 17.500
Thickness = .375
d18 = 179.9


If not, what am I doing wrong?
(I have to be screwing up the ( ) somewhere?)

If so, why doesn't it work?

Thanks,
-Ken

You have 2 distances multiplied (OD and D18) which gives you squared units
for example :-

i.e d1=10mm
d2 = 3mm

d1*d2 :-

10mm * 3mm = 30mm^2

To get an answer of 30mm, use the following "(d1*d2)/1mm"

As shown above the easiest way to get round this is to put "/1mm" on the end
of your formula (or "in" if you use inches) - Obviously ignore the quotes.

There are more elegant solutions using the isolate function but this should
get you going.

Hope this helps

Rory

What about:

2*d18 * (...

Will that work maybe?

Ahhh..

Thanks for the suggestions.

What did end up working, was that I added deg after my 360.

Thanks again,
-Ken

( ( PI * ( OD - Thickness ) ) / 360 deg ) * d18 * 2 ul
you needed the degrees on the 360

Thanks Drew,

That hit me like a ton of bricks after reading Rory and Larry's replies.
