Command to Change "fit text" property of a small dimension

Rhino Rhino for Windows

Is there a command to run or script that will automatically flip the “fit text” of a dimension from auto to either left or right so it doesnt interfere with adjacent dimensions. Due to the way Rhino6 now displays dimensions, all of our annotation styles have had to be rewritten and now it either overlaps adjacent dimensions or when it pulls the dim from a command, it drops arbitrarily to either side. I have to then select each dim and scroll down in the properties panel and change the text fit on each dim.

If there is a command associated with this property, it could be written into a macro to change the property on multiple selections.

Hello - here is a quick script that may do what you want-

import rhinoscriptsyntax as rs
import Rhino
import scriptcontext as sc

def DimForceLeft():
    
    def dim_filter(rhino_object, geometry, component_index):
        if isinstance(rhino_object, Rhino.DocObjects.LinearDimensionObject):
            return True
        return False
        
    id = rs.GetObject("Select a dimemsion to force left", filter = 512,  preselect=True , custom_filter = dim_filter)

    obj = rs.coercerhinoobject(id)
    geo = obj.Geometry
    
    geo.ForceTextPosition = Rhino.Geometry.Dimension.ForceText.Left
    obj.CommitChanges()

    sc.doc.Views.Redraw()
    pass
    
if __name__ == '__main__':DimForceLeft()

To use the Python script use RunPythonScript, or a macro:

_-RunPythonScript "Full path to py file inside double-quotes"

If you change the ‘Left’ where ever it turns up to ‘Right’ or ‘Auto’ you can make the orthers - shout if you need help with that…

can you run a check in Python to see if a dim has been pulled out to the side and would need to be forced left or right?

In R5, the dimension style would pull our small fractional dimensions inside the arrows, and then above. Is there a way to script this?

Hello - DimRecenterText may help - resets a moved dimension text - but I am not sure I know what you mean.

this is what i get when i try to use this code in a python script after copy/paste into a new .py file.

any idea what i need to add to the code to fix?

Hello - I edited the snippet above - it needed some import statements at the top

import rhinoscriptsyntax as rs
import Rhino
import scriptcontext as sc

@pascal

With one of the recent release candidate updates, this script seems to be broken.

When running the script, it doesnt give an error but it has no effect on the selected dimension.

Also, is there a way to have 1 script with directional subfunctions ( L for Left, R for Right, A for Auto, I for Inside, etc.) ?

Hello - I see - it looks like some functions changed with 6.20… see how this one works

import rhinoscriptsyntax as rs
import Rhino
import scriptcontext as sc

def DimForcer():
    settingList = ['Auto', 'Left','Right', 'Inside']

    fitList = [Rhino.DocObjects.DimensionStyle.TextFit.Auto,
    Rhino.DocObjects.DimensionStyle.TextFit.TextLeft,
    Rhino.DocObjects.DimensionStyle.TextFit.TextRight,
    Rhino.DocObjects.DimensionStyle.TextFit.TextInside]
    
    
    def dim_filter(rhino_object, geometry, component_index):
        if isinstance(rhino_object, Rhino.DocObjects.LinearDimensionObject):
            return True
        return False
        
        
    while True:
        idx = 0
        
        if sc.sticky.has_key('DIM_FORCE'):
            idx = sc.sticky['DIM_FORCE']
            
        go = Rhino.Input.Custom.GetObject()
        go.SetCustomGeometryFilter (dim_filter)
        go.AddOptionList("Force", settingList, idx)
        go.EnablePreSelect(False, False)
        go.SetCommandPrompt("Select a linear dimension")
        
        rc = go.Get()
        
        if go.CommandResult()!=Rhino.Commands.Result.Success:
            return
            
        if rc == Rhino.Input.GetResult.Object:
            obj = go.Object(0)
            
        if rc == Rhino.Input.GetResult.Option:
            idx= go.Option().CurrentListOptionIndex
            sc.sticky['DIM_FORCE']= idx
            continue
        
        rObj = obj.Object()
        geo = rObj.Geometry
        geo.TextFit = fitList[idx]

        rObj.CommitChanges()
    
        sc.doc.Views.Redraw()

    
if __name__ == '__main__':DimForcer()

I think something else changed in the most recent update, this script had been working fine up until the latest update candidate, but now,

thanks for anything you can do.

Hello - it looks like maybe you accidentally added a “\” character to the beginning of the script - if you take that out in a text editor or EditPythonScript, or just grab the code again from above, I think it ought to work.
