equation question
is there a way in the part's equation to make an equation that will pick one or the other dimension based on the biggest one?
im trying to make equations that will auto create my blank size for me and we put the shortest one first, so if we edit the part then what if d1@sketch1 becomes the longest one?
so far after trying everything all i can get is "the syntax of this equation is incorrect"
i have tried a lot of different texts to make the equation so i dont know what i could be doing wrong, thanks a bunch everyone
just trying to figure it all out
chris,
i don't think so. you could consider using excel functionality in a design table instead. excel can do it.

you could use an iif statement.. iif(dim1 > dim2,var1 = dim1,var1 = dim2)
now thats a bit archaic, but it should get the point across..

i know that dim1 and var1 are generic terms
dim1 is "d1@sketch1" in solidworks
but i still get an invalid equation, what do i put in for var1?

throw your equation here.. i'll see if i can get it to work..

blah = (iif("d1@sketch6" > "<A href="mailto:d2@sketch6",var1">d2@sketch6",var1 = "<A href="mailto:d1@sketch6",var1">d1@sketch6",var1 = "d2@sketch6")

ok, so i'm guessing that blah is your variable for your blank, and you just need the biggest size of the two dims?
blah = iff(d1@sketch6 > d2@sketch6,d1sketch6,d2@sketch6)
add quotes where needed..

blah was just a generic name i was giving the equation im still trying to start this whole blank size bom system for our sheet metal parts so i dont have a full name for it yet that will go to the titleblock in the drawing
maybe im not as good as i thought (i have mdb history) but where do i put the quotes in that equation because its just not working wherever i put them
i know this is getting close though and im sure it will work for me as soon as i figure out those little things
thanks a bunch tom

this is just for an equation in your part, or this is for a macro?

just for an equation in my part to put into the file's properties and then carry over to the bom in the drawing

here is an equation driven sketch using an iff statement.. the equation is
"d3@sketch1" = iif("d1@sketch1" > "d2@sketch1", "d1@sketch1" / 2, "d2@sketch1" / 2)
hth..
