Changing dot secondary text problem

Scripting
1

Hey guys, i tried to change a dot secondary text and dosen’t work , what i m missing?

import rhinoscriptsyntax as rs

textDot = rs.GetObject(“Select textDot”, rs.filter.textdot)
textDot = rs.coercegeometry(textDot)
print textDot.SecondaryText
textDot.SecondaryText = “Test”

when you coerce the geometry a copy is made
you just need to reference the actual thing in the rhino document

import scriptcontext as sc
import rhinoscriptsyntax as rs

r = rs.GetObject(' pick text dot', rs.filter.textdot)
td = sc.doc.Objects.FindId(r).Geometry #this is what you want
print(td.SecondaryText)
td.SecondaryText = 'bigger'
print(td.SecondaryText)

Thank you @will_wang for explanantion.
Also you re code make a copy of object ,but with replace function will make it correctly

sc.doc.Objects.Replace(r,td)

sorry forgot to include this
there must be a CommitChanges method in the end

Hi, I cannot get the text dot secondary text to refresh in the rhino document. I tried the CommittChanges, but I got textdot has no attribute CommittChanges. What did i miss?

Try this:

mport Rhino
import rhinoscriptsyntax as rs
import scriptcontext as sc

def coercetextdot(id, raise_if_missing=False):
    geom = rs.coercegeometry(id, False)
    if isinstance(geom, Rhino.Geometry.TextDot): return geom
    if raise_if_missing: raise ValueError("unable to convert %s into TextDot geometry"%id)
    
def test_text_dot():
    dot_id = rs.GetObject('Select text dot', rs.filter.textdot)
    if not dot_id: return
    dot = coercetextdot(dot_id)
    if dot.SecondaryText: print(dot.SecondaryText)
    dot.SecondaryText = dot.SecondaryText + ' Test'
    sc.doc.Objects.Replace(dot_id, dot)
    sc.doc.Views.Redraw()
    
if __name__ == "__main__":
    test_text_dot()

Hi Dale,

You renamed your raise_if variable in one location but not the other… :wink:

Works fine. TQ.
got "unsupported operand type(s) for +: ‘NoneType’ and ‘str’,
if secondary text is empty.

is the CommitChanges workflow not valid anymore?
would you recommend the Objects.Replace paradigm over CommitChanges?

What is the solution for adding secondary text to a dot that does not already have it?

The code that I am trying to use looks like this

geom = rs.coercegeometry(pointGUID, False)
print(geom)
print(type(geom))
geom.SecondaryText(f'{self.pointList[n].deviation:.4f} mm')
sc.doc.Objects.Replace(pointGUID, geom)

The print statements say:

Rhino.Geometry.TextDot
<class 'Rhino.Geometry.TextDot'>

so the geom object is not None

Error is:
TypeError: 'NoneType' object is not callable

(the line number is not shown but the error is from the geom.SecondaryText(…
Which sounds like Rhino thinks it is None?

Hello,

Have you tried geom.SecondaryText = f'{self.pointList[n].deviation:.4f} mm'

Thank you!
My fault for not reading more carefully - I was getting hung up on the NoneType part of the error message.
