Set attribute value for windowed objects

Mikael63

I want to execute a command where I can do a crossing window and set (all included) attribute with tag BET1 to a defined value like ABCD, without further dialog.

Like:

Command
crossing window
enter

or crossing window
command

Howto, easiest?

You can do this via code. Maybe someone can translate this to Lisp

import traceback
from pyrx_imp import Ap, Db, Ed, Ge, Gi, Gs, Rx

print("added command = changeatt")

def PyRxCmd_changeatt():
    try:
        filter = [(Db.DxfCode.kDxfStart, "INSERT")]
        ps, ss = Ed.Editor.select(filter)
        refs = [Db.BlockReference(id) for id in ss.objectIds()]
        atts = [Db.AttributeReference(id) for ref in refs for id in ref.attributeIds()]
        for att in atts:
            if att.tag() == "BOXTYPE":
                att.upgradeOpen()
                att.setTextString("WOOHOO YES!")
    except Exception as err:
        traceback.print_exception(err)

Yep lisp exists, ok a question or 2, my way is a global function, select the attribute in a single block this returns Tagname & Blockname via code, so then ssget the blocks and change the correct attributes. Is this ok only one block name, if yes will post code done many times.

Mikael63

Name of block is always EPCBG1F0
Tag is always BET1
Value is always -XDA001
Value is sometime hidden (other attribute in block is visible)

New value -XDA002

I need to mark those I want to change, some others need to be unchanged.

The idea is to do this without filling forms, like in Find and Replace.

Sorry another question is it just add 1 to last number ? This can be done.

Mikael63

Well, this is what I need just now but for a more common usage, I think edit value in LISP is better.

This is "one time job", but for many drawings.

ALANH

Can you post a dwg please. Need to look at where block EPCBG1F0 is located Model, layouts etc or restrict changes some how. This may be a problem with multiple dwgs.

If you can figure out how to install python

Here’s a sample sledge hammer approach, that will change every attribute in a folder of .DWGs

https://github.com/CEXT-Dan/PyRx

import traceback
from pyrx_imp import Rx, Ge, Gs, Gi, Db, Ap, Ed

import wx
import os, pathlib

def changeit(db : Db.Database, tagValue, textValue):
    ids = db.objectIds(Db.AttributeReference.desc())
    for att in [Db.AttributeReference(id) for id in ids]:
        if att.tag() == tagValue:
            att.upgradeOpen()
            att.setTextString(textValue)

def openSideDrawing(path, tagValue,textValue):
    print("\nProcessing {} ".format(path))
    db = Db.Database(False, True)
    db.readDwgFile(path)
    db.closeInput(True)
    changeit(db,tagValue,textValue)
    db.saveAs(path)
            
def PyRxCmd_doit():
    try:
        tagName = 'FGUIDE'
        textValue = 'WOOHOO YES!'
        dwgext = ".dwg".casefold()

        dlg = wx.DirDialog(None, "Choose input directory","",
                wx.DD_DEFAULT_STYLE | wx.DD_DIR_MUST_EXIST)
    
        if dlg.ShowModal() != wx.ID_OK:
            print("You Cancelled The Dialog!")
            return

        for fname in next(os.walk(dlg.GetPath()), (None, None, []))[2]:
            ext = pathlib.Path(fname).suffix.casefold()
            if ext != dwgext:
                continue
            fpath = '{}\\{}'.format(dlg.GetPath(),fname)
            openSideDrawing(fpath, tagName,textValue)
        print("yay")
    except Exception as err:
        traceback.print_exception(err)
