CAD Attribute Reader example

Popeye · November 26, 2021, 10:55am

In Visual Components 4.4, we’ve introduced a new feature, called CAD Attribute Reader, that reads your 2D CAD data and converts them into 3D layouts.

Attached you can find CAD Attribute Reader.zip file CAD Attribute Reader.zip (973.1 KB). The file has an example 2D drawing, addon’s, code sample and instructions to use the addon.

I faced similar kind of issue last time, I am still searching for some proper solution

parkcheoljin · July 1, 2022, 4:07am

Is it obsolete in version 4.2?

Este · July 4, 2022, 5:07am

The CAD attribute reader requires VC version 4.4, or later, to operate.

Heyaa!

Is it possible that the DWG Attribute Reader is not working anymore in 4.5?
I get the following message when I press on the attribute reader button:
System.IO.FileNotFoundException: Could not load file or assembly ‘System.Text.Encodings.Web, Version=5.0.0.1, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51’ or one of its dependencies. The system cannot find the file specified.

I copied both dlls (Plugin.ReadDWGBlock.dll and System.Text.Json.dll).

Any ideas what I’m doing wrong?

Best

@ProLean zip file updated. The file was missing the required dll. Add System.Text.Encodings.Web.dll to the installation folder and test again

ProLean · October 21, 2022, 3:42pm

Hi @Popeye, thanks for adding the dll.
Unfortunately I still get the error message.
I noticed the dll you attached to the ZIP is from .NET 6.0.
The error message however is complaining about the missing dll with Version 5.0.0.1.
I tried to install .NET 5.0 however it didn’t help either.
How did you get it to work on your side?

I just tried with a clean install, copied the 3 DLL files to the installation folder. It worked with the example dwg file.

MP3 · January 27, 2023, 3:49pm

I just tried to install, and nothing is working. I have a few questions:

What is the typical address of the installation folder? I have been trying C:\Users<Username>\Documents\Visual Components<Version Number>\My Commands?
Does this add-on work with 4.6 professional and premium versions?
Should I be moving all .DLL files and .CS file or just the .DLL files?\

Any ideas?
Thanks!
Update: Turns out I was moving the files to the wrong folder. The folder that I needed to use was:
C:\Program Files\Visual Components\Visual Components <professional/premium version number>

Now I’m having a problem with System.Text.Encodings.Web.DLL

The My Commands folder is only for python addons.
.NET addons (.dll) should be placed in the VC installation folder in Program Files.

Download and unzip the files
Copy the DLL files to the installation folder, for example: C:\Program Files\Visual Components\Visual Components Premium 4.6
Start VC application

@Este Hello
I follow the steps

Download and unzip the files
2.Copy the DLL files to the installation folder, for example: C:\Program Files\Visual Components\Visual Components Premium 4.6
3.Start VC application
But after importing the layout, then Click the DWG Attributes Reader command
An error message popped up

ProLean · April 6, 2023, 11:53am

Got it working by copying a version 5.0 System.Text.Encodings.Web.dll with the same public key as mentioned in the error message (cc7b13ffcd2ddd51) into Visual Components root.
So it seems like the version is the issue.

@Este I guess even though you tested with a fresh VC installation, it might be that the required version 5.0 dll was somewhere available on your PC where Visual Components has access to. Is that possible?

Ireceived this message how did you resolve it

BRIE · January 30, 2024, 1:06pm

kindly help me with the above

LasseLFM · May 2, 2024, 12:16pm

@Popeye @BRIE Is there any guide with pictures explaining where you got the file from?

LasseLFM · May 3, 2024, 4:50am

Can you send me the file or link to the version 5.0 system.Text

LasseLFM · May 6, 2024, 6:53am

@ProLean Where did you download 5.0 System.Text.Encodings.Web.dll with the same public key as mentioned in the error message. i know where to put.

ProLean · May 6, 2024, 5:58pm

@LasseLFM, I’m currently at my laptop where I haven’t installed the CAD Reader.
But I found a version 5.0 on my system, try this one.
System.Text.Encodings.Web.dll (66.9 KB)

LasseLFM · May 7, 2024, 6:04am

Hey agein!
I have tried reinstalling VC, and I got it to work with the ready example. Many thanks! Is it possible to use this DWG reader for all CAD files, or do I need a special file beforehand? Because I tried it on this CAD file.
Layout 1_2024-04-10_MMP.dwg (355.1 KB)

Este · May 7, 2024, 8:13am

I think it supports any dwg file that has block attributes. Make sure that the Read Block Attributes option is enabled when you import the file.

This creates a property called “DWGAtrributes” in the imported model that includes the block attribute details. You can then write a script that reads this data and, for example, loads components and places them in the defined positions.
