iLogic convert decimal to fraction

[Anonymous]

Happy Monday All,

   So Neil helped me to string together part descriptions in iLogic and pass them to the description field in iProperties.

Example: 

iProperties.Value("Project", "Description") = Thickness & " " & Material & " x " & Width & " in. x " & Length & " in. Lg."

 My question now is can I have the values displayed in the "Description" field as fractions instead of decimal values and how would my code read. I found the "FormatAsFraction" function under the "String" snippets but can't seem to get the syntax right. Thanks to all for you patience and assistance. Have a great week.

Hi frank,

Try something like this:

'variables/values that would come from the model
Material = "Steel"
Thickness = .125
Width = 1.5
Length = 6.25

'convert values to fraction
oT = FormatAsFraction(Thickness)
oW = FormatAsFraction(Width)
oL = FormatAsFraction(Length)

'set description
iProperties.Value("Project", "Description") = _
oT & " " & Material & " x " & oW & " in. x " & oL & " in. Lg."

'display to user
MessageBox.Show("Description: " & vbLf & _
iProperties.Value("Project", "Description"), "iLogic")

I hope this helps.
Best of luck to you in all of your Inventor pursuits,

Or something like this if you need to control the precision:

'variables/values that would come from the model
Material = "Steel"
Thickness = 0.103587
Width = 1.5625
Length = 6.3987

'convert values to fraction
oT = RoundToFraction(Thickness, 1/8, RoundingMethod.RoundUp)
oW = RoundToFraction(Width, 1/16, RoundingMethod.RoundUp)
oL = RoundToFraction(Length, 1/32, RoundingMethod.RoundUp)

'set description
iProperties.Value("Project", "Description") = _
oT & " " & Material & " x " & oW & " in. x " & oL & " in. Lg."

'display to user
MessageBox.Show("Description: " & vbLf & _
iProperties.Value("Project", "Description"), "iLogic")

Curtis,

Second example worked like a charm once I got the syntax correct. I really appreciate the assistance. I've watched all the tutorial videos I could on iLogic and couldn't put it together until I saw it applied to what I was doing. All of the stuff in the videos was all theoretical and kind of abstract to me. I think for myself, it all started to come together when I saw it applied to what I'm doing. Thanks again for your help.

How do you do all this in VBA since if you use RoundToFraction(Variable,1/64, RoundingMethod.Round) it throws an error that the Function isn't defined.

Any insight anyone?

You stick to VB.net or iLogic or create your own function in VBA?

The other option:

- Set your parameters up as "Exposed" and use the Custom Property Format to set the unit display as desired.

- Revise your code to look like this:

iProperties.Value("Project", "Description") = "=" & "<Thickness> <Material> x <Width> in. x <Length> Lg."

This utilizes the iProperty expressions (which will show up beside the iProperty as "fx")
