Creating a description relation driven from dimension parameters.

[jason.webb]

Help anyone,

I am trying to create a relation to drive the title's of instances. I have the following and this is not working. Any help would be apprecitated.

1st attempt

/* This if statement relation determines which title to apply to the part, a rectangular tube description or a square tube description.

HEIGHT = D2
WIDTH = D3
WALL_THICKNESS = D5
OAL = D6

If HEIGHT == WIDTH
TITLE = TB SQ height X wall_thickness X oal
else
TITLE = "RECT TB D2 x D3 x D5 x D6"
endif

2nd attempt

/* This if statement relation determines which title to apply to the part, a rectangular tube description or a square tube description.

If HEIGHT == WIDTH
TITLE = "TB SQ" + height + "X" + wall_thickness + "X" + oal
else
TITLE = "RECT TB" + itos(height) + "X" + itos(width) + "X" + itos(wall_thickness) + "X" + itos(oal)
endif

Here is what we use. This is if the parameter is an integer where MOD_HIGH/MOD_WIDE is and integer.

PTC_COMMON_NAME = PART_NAME

PART_NAME = "MOD MTG SHEET, " + ITOS(\
MOD_HIGH) + " x "+ ITOS(MOD_WIDE) + " , DB4K-G1"

If the parameter is a real number the ITOS (Integer to String) function doesn't work
One way around that would be to replace:
ITOS(HEIGHT)
With
ITOS(FLOOR(HEIGHT)) + "." + ITOS( (HEIGHT - FLOOR(HEIGHT)) * 100)

I forgot to mention my title is currently set to a string. I have tried to floor the height, width and mat_thickness parameter and for the material thickness it resorts to nothing. Which makes sense as most of my instances are less than 1/2" thick. I have also tried the ins with the same results.
