Hi - in the attached file I have created a parameter wheel_diameter. I then want to use the parameter in the formula associated with dimension d100.
The formula associated with d100 is ( ( ( 54 + 3 ) / 24 ) * 4.76 ) * 1 mm.
What I want to do is replace the number 54 with wheel_diameter. Then I can change wheel diameter and the drawing changes.
But I cannot work out how to simply replace 54 with wheel_diameter. When i change the number for the parameter the dimension will not accept it.
Many thanks in advance for any help.
