Help parameters mm to units

[Anonymous]

 Is it possible to convert mm to units ?
I'm measuring the length of a line (100mm)
Length/12/2
And the result is 4,1666 mm and I would like it to be translated and rounded to 4 units

It's really hard to interpret what you are asking. We need more details. Images help, also more explicit steps would help.

Despite that, I will attempt to answer what I think are your questions. In Parameters dialog you cannot change units. You can however, type any unit into a dimension. For instance, while working in mm you can enter "2 in". Since you are working in mm, the display will show mm, but the distance will be 2 inches absolute length.

If you want a parameter to be 4 instead of 4.167, just enter 4 instead of 100/12/2 as the expression.

I hope that helps, but without more information it's really hard to tell what you want to do, and what your actual question is.

Thanks,

I am trying to make some wood finger joints, that hopefully will be driven by the "length"

Got it. Here is the solution:

User parameters can be unitless. Just divide by 1 mm (or what ever unit you are in) to get a unitless result.

Use that in a pattern. This is a simple version of what you need.

Let me know if this helps.

Thanks,

I'm so impressed awesome support 🙂
I really love to learn some more about what the parametric is capable of doing, is there a list of commands somewhere or other resources you could point me to ?

is there a way to rounding numbers

Hi,

To round, you put your current expressions in parenthesis, and prefix 'round'. This will round to the closest whole number. Alternative you can use 'floor' to round down to the nearest whole number, or 'ceil' (as is ceiling) to round up to the nearest number.

So your expression would look like:

round(length/width)

Let me know if that works for you!

@Anonymous You are correct, thanks for explaining that.

Here is the learning page that explains the parameters dialog.

This is awesome

This is a professional forum.

Can you explain your issue in professional language (and illustrate with pictures/actual Fusion *.f3d file)
When I was in HS (50 yrs ago) this topic (how to handle units) was taught in math class.

[istvan_palotai]

It is still not possible to refer to a variable for the number of pieces in any pattern.
just like this: Quantitiy: ( ( d287 / mm ) / 2 )
If you determinate a dimension like this: Length WORKING

Parameter table: Length : 255/2 +Length2/3 mm  WORKING

It will work ! Fine 
But if you create a NO UNITS parameter with an expression of: Length/2 It will not support the Length variable.

You have to cancel out units - just like in HS (and College) math classes.

The instructor (at least in the classes I took in the last century) were always emphasizing to handle your units.

You would not pass the class if you did not properly handle units. (I took a lot of math classes.)

Can you Attach example *.f3d class.

I have always taught students to write out their equations (including units) in pencil before attempting to enter into CAD software.  (I taught several different CAD softwares.)
