Creo/ProE Drawing Repeat Region/BOM Syntax...This is a Wiki type Doc so Please contribute! :-)

100% helpful (1/1)

This is a document so please edit it and add, correct, &/or clarify how you see fit.  Then we can all use this as a point of reference when dealing with Repeat Regions/BOM programming.  If you don't want to edit it but still want to contribute, then just leave a comment.  Thanks!

mod

 mod(#n,#d)

Modulus function.  Also known as Remainder function because gives just the remainder. e.g. n/d (numerator/denominator):

10/2=5 Remainder=0 (10/2+0/2)

10/3=3 Remainder=1 (9/3+1/3)

10/4=2 Remainder=2 (8/4+2/4)

 

In Programming Modulus can be useful to do many things. e.g.

  1. Determine if Number is Odd/Even
    [if mod(n,2)=0 then n is even]
  2. Clock arithmetic

[mod(9+5,12)=2pm]

  1. Truncating decimal values
  2. Wrapping values into a certain range

[given mod(n,360) to determine what quadrant a particular angle falls in for the unit circle)
if Remainder       0-90, then Quad.1
if Remainder   90-180, then Quad.2
if Remainder 180-270, then Quad.3

If Remainder 270-360, then Quad.4]

Comments

This is a good start but is far from comprehensive.  Hopefully others will contribute to this doc to get it up to par!

Thank you TomUminn!  I could not find this when I searched the help, searching these forums, tried navigating through the help (I didn't realize to look under fundamentals!), or opening a call/case with PTC and asking them.  After not being able to find it in any of those locations (especially the TS) I thought it didn't exist.  Thanks again!

Fantastic document Lawrence!

Those links do not work any more.  Here is one of them and then you can jump around from there:

https://support.ptc.com/help/creo/creo_pma/usascii/#page/fundamentals%2Ffundamentals%2Ffund_seven_sub%2FAbout_Functions_Used_in_Relations.html%23

Does anyone know if you can put multiple lines on a single line using something like a new line or next line character?

  • E.g. If x=="1" `n y=="2" `n ENDIF

Although this may be useful in the actual code I would really like to use it in the Evaluate Expressions dialog.
