Creating relations between dimensions

gustavo_chelles

Hi, I would like to create relations between dimensions, something like d2=d1+3, but I don't find the way of doing this.  Can anyone give me a tip?

Hi gustavo,
this can be done using variables:
 Create a variable named 'd1' (it'll appear in the feature tree)
 In a feature or sketch, you can type a formula. type "#" and you'll see a list of parameters you've created (you can even create one there and then).

when you type in a sketch for a dimension "#d1 + 3" it won't work because it can't add numbers to millimeters or inches.
so type "#d1 + 3 mm" and it'll work.

you can also go ahead and create a new variable. name it "d2" and the value can be calculated.

good luck

Hello Gustavo. Create a variable named d1 and assign a value to it. If the value is 2 and you are working in inches It will look like this: #d1= 2in   . Now you can use d1 in the equation for d2 but you must add a unit type to the 3. When you are beginning to enter d2's dimension, hit the pound(#) key. This will call up a list of created variables and you can select d1 and go on from there. d2's dimension should look like: #d1+3in - Scotty
