Select associated objects a field autocad

[Luís Augusto]

Hi guys, is there any command that performs the selection of objects associated with an object field?

I'm using an excellent routine performed by Lee Mac to make the sum of texts. At the end of addition, it generates a field.

In some moments I need to check the path where I spent. It would be very interesting if we could make a quick selection using the ID of the objects contained in the field.

I should point out that I still have no experience with the Lisp language.

Thank in advance.

Luis Augusto.

You'll need to first parse the FieldCode string, and then iterate the appropriate Block Object given the ObjectId extracted.

Dear BlackBox, thanks for the reply. Unfortunately still can not create my own codes. Hopefully soon get.

Tharwat, thanks for your reply.

Unfortunately, the program did not work on my machine here, also did not return error.

I am attaching the design to perform a test.

I appreciate everyone's attention.

Beautiful job Lee.

Congratulations. Not even in a dream could imagine something so perfect for my situation.

This routine is fantastic, I run the commands zoom and pan, temporary lines keeps the same way.

Surely the program will greatly improve my work.

I can post the code for others with the same need to see the solution?

 

Thank you all.

 

Best regards,

That's odd , I tried the code on Cad 2010 and 2013 and it works well .

 

The routine ask you to pick on field string then it will draw a vector line to the related text entities to that field .

 

Are you using my code separately or you are adding them to another codes ?

Tharwat, I do not dare to change codes. I am trying to understand so many parentheses.

Tomorrow i will test your routine on other machines and give you feedback.

I believe that the forum users here could do the same, thus we would have two solutions.

Thanks for disposal.

How will you Tharwat?

As promised, I tested the program on three machines. Two OS with 32bits and 64bits another.

There is a limitation in 64bit OS. With 32bit OS works very well. I really liked the fact that you can select other fields and keep the old temporary line.

Another observation is how to zoom and pan commands eliminate these temporary lines, the lines would be desirable to remain until press any key.

You can make these improvements?

 

Thank you for sharing your work with us.

Hello Lee

Do not want to seem abused, but I was very curious.

I am using this routine to check the way I did when I add the length of a cable layout for an electric whip.

Our colleague fixo is helping me with a routine to facilitate the completion of the table From / To. The program will generate a calculated field within the table.

When accessing a FIELD within the table, it is a bit strange the line from the origin, so I had the following idea.

 

It would be possible to change the program so that the selection of the FIELD, the source was not the text but a block with the name "NewOrigin" in the center of the layout?

Hi Luís,

 

I hadn't tested the program with fields located within table cells, but will look to resolve this issue when I get some spare time to work on the program.

Hi Lee,

I think I did not express myself well.

I believe that in my case, a block as the source, would be an excellent solution for the type of work I do. In certain situations, my list of cables may be too far from the layout of the electrical harness.

I plan to deploy your code after the sum of the cables. At this time, IDobjects must be in program memory yet. Thus the existing function would direct origin of the lines to the block NewOrigin. That way I can make the conference the way immediately.

Sorry for the misunderstanding.

 

Regards, Luis Augusto.

Hello Tharwat.

Sorry for the delay, I not had the opportunity to test before.

I installed VirtualBox on my machine. Now I can test code for 32bit OS.....

That's it, your code works perfectly, however, with the last review, he missed an interesting feature, which was to select multiple objectFIELDS. No problem.

Congratulations my friend, I hope to one day be able to write my own code too.

Thank you for your test and for following your promises with it , it is much appreciated .

 

Don't worry , you'd write your own codes if you insist on learning and working on programming daily , and I wish you best of luck .
