Create OrdinateDimension by RhinoCommon

Scripting
1

Dear all,

I am trying to create an ordinate dimension by scripting. Since ordinate dimensions are not available in in the rhinoscriptsyntax I want to solve this problem by rhino common (I should say that I don’t have much experience in rhino common). Here is my try:

import rhinoscriptsyntax as rs
import Rhino
import scriptcontext as sc

dim_scale = 5
dimstyle = "dim01"
if not rs.IsDimStyle(dimstyle):
    dimstyle = rs.AddDimStyle(dimstyle_name=dimstyle)
rs.DimStyleTextHeight(dimstyle, height=2)
rs.DimStyleLinearPrecision(dimstyle, precision=1)
rs.DimStyleArrowSize(dimstyle, 1.250)
rs.DimStyleExtension(dimstyle, 1.250)
rs.DimStyleScale(dimstyle, scale=dim_scale)
rs.DimStyleOffset(dimstyle, offset=2)
rs.CurrentDimStyle(dimstyle)

index = sc.doc.DimStyles.Add("dim01")
ds = sc.doc.DimStyles[index]

odim = Rhino.Geometry.OrdinateDimension()
odim.Create(dimStyle=ds,
	plane=rs.WorldXYPlane(),
	direction=Rhino.Geometry.OrdinateDimension.MeasuredDirection.Xaxis,
	basepoint=Rhino.Geometry.Point3d(0,0,0),
	defpoint=Rhino.Geometry.Point3d(100,100,0),
	leaderpoint=Rhino.Geometry.Point3d(120,120,0),
	kinkoffset1=5,
	kinkoffset2=5
)

sc.doc.Objects.AddOrdinateDimension(dimordinate=odim, attributes=Rhino.DocObjects.ObjectAttributes(), history=None, reference=False)
sc.doc.Views.Redraw()

The code doesn’t return any errors, but it doesn’t add a ordinate dimension as well. Does anyonr have a suggestion what has to be done?

Hi @peter.zock,

Here is a simple example:

import Rhino
import scriptcontext as sc

def test_ordinate_dimension():
    style = sc.doc.DimStyles.Current
    plane = Rhino.Geometry.Plane.WorldXY
    bp = Rhino.Geometry.Point3d(0.0, 0.0, 0.0)
    p1 = Rhino.Geometry.Point3d(4.0, 4.0, 0.0)
    p2 = Rhino.Geometry.Point3d(1.0, 2.0, 0.0)
    dir = Rhino.Geometry.OrdinateDimension.MeasuredDirection.Xaxis
    # https://developer.rhino3d.com/api/RhinoCommon/html/M_Rhino_Geometry_OrdinateDimension_Create.htm
    dim = Rhino.Geometry.OrdinateDimension.Create(style, plane, dir, bp, p1, p2, 0.5, 0.5)
    sc.doc.Objects.Add(dim)
    sc.doc.Views.Redraw()
    
if __name__ == "__main__":    
    test_ordinate_dimension()

Hello Dale,

thanks a lot for your reply. I can now try out better what works and what doesnt. I guess i dont undertsand properly why i cant use the create methode, after Initializes a new instance of the OrdinateDimension class. Is this something special about the dimension class or do I lack some general python understanding at this point?

Best Peter

Hi @peter.zock,

If you look at the OrdinateDimension.Create help, you’ll see that it is a static function that returns an OrdinateDimension, not a member method on the class.

I see, thanks for your help!
