Python + AutoCAD, create Table and Hittest

 

In this example, I’ll be importing AxApp24, ActiveX wrappers that are a part of PyRx

Using ActiveX is the easy way to create Tables. Table’s in ARX and .NET have gone through some function changes over the years that can sometimes make it a hassle, at least from a scripting language point of view. Also in this example, I show one method of getting access to a Table’s cell without having to manually select the table first. 

 

import PyRx as Rx

import PyGe as Ge

import PyGi as Gi

import PyDb as Db

import PyAp as Ap

import PyEd as Ed

import traceback

import AxApp24 as Ax

import AxAppUtils24 as AxUt

def PyRxCmd_makeTable():

    try:

        axApp = Ax.getApp()

        axDoc = axApp.ActiveDocument

        # pick a point for the table location

        tablePnt = axDoc.Utility.GetPoint("\nTable location: ")

        # point, rows, columns, row Height, row width

        axTable = axDoc.ModelSpace.AddTable(tablePnt, 5, 5, 10, 30)

       

        #:)

        axTable.SetTextString(0, 0, 1, "My Py Table")

    except Exception as err:

        traceback.print_exception(err)

def PyRxCmd_hitTest():

    try:

        axApp = Ax.getApp()

        axDoc = axApp.ActiveDocument

        # view vec, just use a Z vector

        hitVec = (0, 0, 1)

        hitPnt = axDoc.Utility.GetPoint("\nSelect cell: ")

        # combine the hitPnt with vsmax to make a fence

        fence = hitPnt + axDoc.GetVariable("VSMAX")

        axSs = axDoc.SelectionSets.Add("AXTBLSS")

        axSs.SelectByPolygon(Ax.constants.acSelectionSetFence,

                             fence, [0], ["ACAD_TABLE"])

        #do the hit test

        for axEnt in axSs:

            axTable = Ax.IAcadTable(axEnt)

            hit = axTable.HitTest(hitPnt, hitVec)

            if hit[0]:

                cellstr = "Cell={},{}".format(hit[1], hit[2])

                axTable.SetTextString(hit[1], hit[2], 1, cellstr)

                return

    except Exception as err:

        traceback.print_exception(err)

    finally:

        axSs.Delete()
