How to make a Revcloud in Python for AutoCAD

 

There isn’t a “revcloud” entity type in Autocad, but you can make one with a polyline and enlisting the help of send command.  Here’s the sample code

 

import traceback

from pyrx import Ap, Ax, Db, Ed, Ge, Gi

@Ap.Command()

def myrevcloud() -> None:

    try:

        axApp = Ap.Application.acadApplication()

        doc = axApp.activeDocument()

        ms = doc.modelSpace()

        # coords for the cloud and create a polyline

        coords = [

            Ge.Point3d(0, 0, 0),

            Ge.Point3d(0, 1000, 0),

            Ge.Point3d(1000, 1000, 0),

            Ge.Point3d(1000, 0, 0),

            Ge.Point3d(0, 0, 0),

        ]

        pl = ms.addPolyline(coords)

        # use send command to create the revcloud, note the (A)arc length

        handle = '(handent "{}")'.format(pl.handle())

        doc.sendCommand("revcloud A {} Object {} Y ".format(200, handle))

    except Exception as err:

        traceback.print_exception(err)

 

And the result:
