Greetings!!!
Creating User Parameters, can we use trigonometric functions? and can we add these to linear (mm) parameters?
Can we add the Values irrespective of Units i.e. Inch/ Deg/ Unitless
Example: d0 (In) = d1 (In) +d3[ul] + (sin(Variable_Angle))
In value = In Value + ul Value + deg Value
Thanks in advance.
You cannot mix units. So in your equation, you will need to do something like this:
d0 = d1 + 1 in * (d3 + sin(Variable_Angle))
Note that a sine is a ratio and therefore has no units.

Yes, you can use trigonometric functions, you just need to have some caution with units, to sum them like you shows, the units must be the same.

You can mix units as long as the resulting equation makes sense - just like writing it out by hand.
The resultant value must have a single unit (or unitless (ul)) depending on logic.
I had to do something to figure arc length a few years ago (I think the capability has been added to the software since). As a follow-up question, am I remembering correctly that I was forced to use Radians rather than degrees?
I could be mis-remembering... 😉
I don't know about "forced" (can't remember last month, let alone a few years ago!), but using radians makes working with arc lengths a lot simpler.

I have posted arc-length solutions here (prior to 2013) that did not require using radians rather than degrees.
