[procad] writing a Relation

[jlippeth]

Good Afternoon

I need to write a relation and having trouble finding the correct
nomenclature.



Project scope:

I am creating Spirolox Retaining Rings with quilt bodies to be used to
cut out the groove and c'bore features.

Now I could create a family table, but I want to use relations.



Relation description;

Shaft diameter = SD1

Groove dia = SD5

How would I write,

IF SD1 = 1.125 then SD5 = 1.082

IF SD1 = 1.250 then SD5 = 1.202

IF SD1 = 1.375 then SD5 = 1.323



Etc...



Hopefully I am clear in my request, Thanks

IF SD1 == 1.125 /*make sure you get the double equal sign in the IF
lines.
SD5 = 1.082
ELSE
IF SD1 == 1.250
SD5 = 1.202
ELSE
IF SD1 == 1.375
SD5 = 1.323
ELSE
SD1 = 1.375 & SD5 = 1.323 /*this is so if some value other than one
of the three is entered that it gets a default value equal to one of the
three with the correct SD5 value also.
ENDIF
ENDIF
ENDIF

Hope that helps,

Thanks all with some good tips, Brian had the correct syntax with double
==

Here is what I came up with.

IF SD1 == 1.125 /Shaft diameter
SD5 = 1.082 /Groove Dia.

SD4 = .042 /Groove width
ELSE
IF SD1 == 1.250

SD5 = 1.202

SD5 = .048
ELSE
IF SD1 == 1.375
SD5 = 1.323

Sd4 = .048

ENDIF

ENDIF

ENDIF



Thanks again, Happy Friday to All!
