Use Formulas, Parameters, Labels to Change the Display Text of a Dimension

[brianorser]

Hello

I need a dimension to display a different number than the unit length of the measured object. In other words, if the dimension is measuring an object that is 1' long, I need the dimension to instead display (1' * .9) or "0.9". I am ready to use any means, including Grasshopper or Python or C+, and am able to invest significant time in creating this solution.

I have been trying using labels and global parameters, but am falling short.

Thank you,

Brian

Why can't you scale the model to the correct size instead of faking the dimensions?

I need the drawings to display both Imperial dimensions (for the Building Department) and Shaku, a traditional Japanese decimal system which the carpenters will use to build the building.

[ToanDN]

Yes I got that. Link the rhino model in Revit, choose feet for import units, then select it, edit type and change Scale factor from 1 to 0.9...

Hello ToanDN

Your suggestion is a method for scaling the model, not a method for dimensioning and creating schedules in Feet-Inches and Shaku.

[ToanDN]

Exactly. Now you have two instances of the link. One scaled 1:1 to dimension in shaku. One scaled  0.9:1to do dimension in feet.

You could try manully replacing dimension value with text - which is a lot of manual work.

Then create two different types of Dimension Styles: one in Imperial and one in traditional Japanese.
Once everything is dimensioned, duplicate the View with Deatiling -> select all instances of dimensions -> replace them with other type.

Hi, create a detail item line based family for the dimensions. Then you can create a scaled value of the length

This is an interesting workaround--thanks. Not ideal, but something to consider.

Hi

This would only work for us if the replacement value is calculated automatically. I'll need to pursue that in Python or Dynamo.
