Python with CMS IntelliCAD 14.1

[Danielm103]

Super cool to see the progress IntelliCAD has made with their C++ API. I’ve been working to port pyrx, still not released, there’s a couple small issues I need to work out

 

import traceback
from pyrx import Ap, Db, Ge

# -----------------------------
# Simple spline-based vector font
# -----------------------------
FONT = {
    "H": [[(0, 0), (0, 10)], [(5, 0), (5, 10)], [(0, 5), (5, 5)]],
    "A": [[(0, 0), (2.5, 10), (5, 0)], [(1.2, 5), (3.8, 5)]],
    "P": [[(0, 0), (0, 10)], [(0, 10), (5, 9), (5, 6), (0, 5)]],
    "Y": [[(0, 10), (2.5, 5)], [(5, 10), (2.5, 5)], [(2.5, 5), (2.5, 0)]],
    "N": [[(0, 0), (0, 10)], [(0, 10), (5, 0)], [(5, 0), (5, 10)]],
    "E": [[(5, 0), (0, 0), (0, 10), (5, 10)], [(0, 5), (4, 5)]],
    "W": [[(0, 10), (1.2, 0), (2.5, 6), (3.8, 0), (5, 10)]],
    "R": [[(0, 0), (0, 10)], [(0, 10), (5, 9), (5, 6), (0, 5)], [(0, 5), (5, 0)]],

    spline = Db.Spline(arr, 3, 0.0)
    ms.appendAcDbEntity(spline)

    for ch in text:
        strokes = FONT.get(ch.upper(), [])
        for stroke in strokes:
            add_spline(ms, stroke, cursor, scale)
        cursor.x += spacing * scale

Here’s a test extracting data from multiple drawings

 

import traceback
import pandas as pd
import os

from pyrx import Ap, Db, Ed, Ge

def proccessDrawing(db: Db.Database, data: dict):
    blk_dict = db.getBlocks()
    fname = os.path.basename(db.getFilename())
    data[fname] = []
    for name, id in blk_dict.items():
        if name != "RMNUM":
            continue
        btr = Db.BlockTableRecord(id)
        for refid in btr.getBlockReferenceIds():
            blkref = Db.BlockReference(refid)
            for attid in blkref.attributeIds():
                attref = Db.AttributeReference(attid)
                data[fname].append(attref.textString())


def openSideDatabase(dwg_path: str, data: dict):
    sdb = Db.Database(False, True)
    sdb.readDwgFile(dwg_path)
    sdb.closeInput(True)
    proccessDrawing(sdb, data)


@Ap.Command()
def doit():
    try:
        data = {}
        dwgs = Ap.Application.listFilesInPath("E:\\FloorPlans", ".dwg")
        for dwg in dwgs:
            openSideDatabase(dwg, data)

        df = pd.DataFrame(data)
        print(df)
    except Exception as err:
        traceback.print_exception(err)

 

output :

test with wxPython

 

[CyberAngel]

Some really cool stuff here

[Danielm103]

Thanks!

 

I’m always rooting for the underdog, I guess to promote competition in the space. I’ve been goofing around with the clones since the early days.

I think before version 9. Every year, I download the trial and try out the IARX SDK. The trial is 14 days, this is the first time I was able to get past day 1 and run some real tests.

 

Here’s my little mini review of the API.

 

- I was able to compile my custom object https://github.com/CEXT-Dan/ArxTin

While I didn’t test all the protocols, the important ones work great!

dwgOutFields, dwgInFields, subWorldDraw, subTransformBy etc.

 

The most impressive thing besides it working, is the subWorldDraw performance. In this sample, I’m pushing 10s of thousands of edges to the graphics interface and transformby is as fast a moving a line. A $250 cad is out performing a $1200 cad by 10x

But there’s stuff missing, from the automated tests in PyRx

 

"collecting ... collected 529 items / 210 deselected / 3 skipped / 319 selected"

 

There are 210 tests that I had to disable to get a clean run. I’m still working through them, I disabled the whole class on some tests

all the test_Ax**** tests are not accurate, I've not worked through them yet

I was able to connect with ITC Directly and report the items I felt are important from an API perspective.

AcRxClass::dxfName()    is null with AcDbObject
AcDbObject::close()     has an access violation if called twice.

 

I think the next release or so of IntelliCAD will be a real competitor in the space.  Assuming pricing is stable, there’s no reason to buy any ‘lite’ version of CAD
