How change text size of dim in pythonscript

Scripting

1

I use ‘Add Aligned Dimension’ in python script but text height so small. I change text height i but not.

import rhinoscriptsyntax as rs
import scriptcontext as sc
import Rhino

def GetOffsetMidpoints(pl_ID,dist,plane):
    #get offset figure and offset points
    bb=rs.BoundingBox(pl_ID)
    xform=rs.XformScale(1.1,(bb[0]+bb[2])/2)
    bb=rs.PointArrayTransform(bb,xform)
    pl=rs.coercecurve(pl_ID)
    sharp=Rhino.Geometry.CurveOffsetCornerStyle.Sharp
    off_pl=pl.Offset(bb[2],plane.Normal,dist,sc.doc.ModelAbsoluteTolerance,sharp)
    if off_pl:
        segs=off_pl[0].DuplicateSegments()
        mids=[(seg.PointAtStart+seg.PointAtEnd)/2 for seg in segs]
        return mids
    
#closed planar polyline filter
def pl_filt(rhino_object, geometry, component_index):
    return rs.IsPolyline(geometry) and rs.IsCurveClosed(geometry) and rs.IsCurvePlanar(geometry)

def DimClosedPolylines2():
    msg="Select polylines to dimension"
    pl_IDs=rs.GetObjects(msg,4,preselect=True,custom_filter=pl_filt)
    if not pl_IDs: return
    dist=rs.GetReal("Distance to offset?",5,0)
    if dist is None: return
    
    rs.EnableRedraw(False)
    for pl_ID in pl_IDs:
        verts=rs.PolylineVertices(pl_ID)
        opts=GetOffsetMidpoints(pl_ID,dist,rs.CurvePlane(pl_ID))
        if opts:
            #checksum in case offset went wrong
            if len(opts)+1==len(verts):
                for i in range(len(verts)-1):
                    rs.AddAlignedDimension(verts[i],verts[i+1],opts[i])
DimClosedPolylines2()

Hi xiix
You need to create DimStyle，like this:

dimStyle_name = "Dim"+str(i)
                    dimStyle = rs.AddDimStyle(dimStyle_name)
                    dim = rs.AddAlignedDimension(verts[i],verts[i+1],opts[i],dimStyle)
                    rs.DimStyleTextHeight(dimStyle,30)

code:

import rhinoscriptsyntax as rs
import scriptcontext as sc
import Rhino

def GetOffsetMidpoints(pl_ID,dist,plane):
    #get offset figure and offset points
        bb=rs.BoundingBox(pl_ID)
        xform=rs.XformScale(1.1,(bb[0]+bb[2])/2)
        bb=rs.PointArrayTransform(bb,xform)
        pl=rs.coercecurve(pl_ID)
        sharp=Rhino.Geometry.CurveOffsetCornerStyle.Sharp
        off_pl=pl.Offset(bb[2],plane.Normal,dist,sc.doc.ModelAbsoluteTolerance,sharp)
        if off_pl:
            segs=off_pl[0].DuplicateSegments()
            mids=[(seg.PointAtStart+seg.PointAtEnd)/2 for seg in segs]
            return mids
        
    #closed planar polyline filter
    def pl_filt(rhino_object, geometry, component_index):
        return rs.IsPolyline(geometry) and rs.IsCurveClosed(geometry) and rs.IsCurvePlanar(geometry)

    def DimClosedPolylines2():
        msg="Select polylines to dimension"
        pl_IDs=rs.GetObjects(msg,4,preselect=True,custom_filter=pl_filt)
        if not pl_IDs: return
        dist=rs.GetReal("Distance to offset?",5,0)
        if dist is None: return
        
        rs.EnableRedraw(False)
        for pl_ID in pl_IDs:
            verts=rs.PolylineVertices(pl_ID)
            opts=GetOffsetMidpoints(pl_ID,dist,rs.CurvePlane(pl_ID))
            if opts:
                #checksum in case offset went wrong
                if len(opts)+1==len(verts):
                    for i in range(len(verts)-1):
                        #
                        dimStyle_name = "Dim"+str(i)
                        dimStyle = rs.AddDimStyle(dimStyle_name)
                        dim = rs.AddAlignedDimension(verts[i],verts[i+1],opts[i],dimStyle)
                        rs.DimStyleTextHeight(dimStyle,30)
    DimClosedPolylines2()

I hope this help you.

I’m trying edit like this but not ok. When dim auto select default but don’t change height text. The Script create many option but ‘command dim’ don’t use it

    dimStyle = rs.AddDimStyle(dimStyle_name)
    rs.DimStyleTextHeight(dimStyle,textHeight)
    rs.DimStyleArrowSize(dimStyle,textHeight)
    return dimStyle


DimClosedPolylines2()

I modified the code.

Thank you! i’m reinstall rhino and trying it!

Wow. Great little script, was hard to track this one down when searching for automatic dimensions in python script. Would be good to collate in a common github repo… wink wink.
