Simple + and - in an equation. Why doesn't this work?

todd_hammer272todd_hammer272 Member Posts: 2
I'm trying to use a simple + in a dimension equation and its not working. 
I've set a variable #thickness
My simple equation I'm putting in a dimension:   #thickness+.03

The following works:  #thickness/2

+  and - doesn't seem to work. 

What am I doing wrong?  
Thanks in advance.

    Interesting. I just tired the function out and NO it doesn't work.
    #x+#y works but #x+1 gives an error.
    That was unexpected. Been using calculated dimensions a fair bit but only with variables.

    Values have units so all terms in an equation must be of the same type such as length.

    If you use #thickness + .03mm and give the 0.03 value units, it will work.

    Thanks.
    Just checked what happens when "number" is used for variable instead of "length" and the problem goes away.
    Current system units are placed for the whole result. #X+1 becomes (#X+1)mm in a dimension.

    I find that having units helps me get correct logic...

    You can also do this; make your variables unitless. Then you can use (#x + 1) mm or (#x + 1) inch

    Hello all,
    Don't you know if its possible to use parameters as part of equation for another parameter?
    Example:
