Detecting a valve which is not a block

[muralik7KY37]

Hi,

We have P&IDs where the valves are not yet blocks and we want to convert them into blocks. If there any way to detect a collection of lines, circles as a valve object and programmatically convert into a block?

Thanks,

Murali

The other way around. Select all blocks and use HIDEOBJECTS.

Depends on how they are created, are they in same layer and so on . Post a sample drawing in DWG

[muralik7KY37]

Hi,

There are no blocks in the drawing already. The lines, circles, etc. making the symbol all lie in same layer. Please find attached a sample drawing with the symbol list included. I was thinking there would be a method to select similar group of objects in lisp. The symbol may be rotated or slightly scaled.  Any help is appreciated.

HERE is a link for you to get an idea of what you asking from us.

So to answer your question - YES, there is. Unfortunately, it has nothing to do with AutoCAD (anymore).

Using tool similar to what @ВeekeeCZ has show would be the answer to your request. What I see from your sample, you will have to recreate all blocks and than replace them inside drawing. This blocks are standard in your branch, so I guess there must be a source i.e that would make this job a bit easier.

This task requires organized approach and is not so easy to do.

Blockify, What an appropriate name for that tool.

What do you mean by that @ВeekeeCZ ? was it a function available before?

Thank you. Following along the line, I found https://forums.autodesk.com/t5/visual-lisp-autolisp-and-general/blockify/td-p/8629318 which describes similar lisp for Autocad

No, no. What I had in mind was that there will always be a question of how these clones were born to live. But that's not what I wanted to discuss. I really like the tool and hopefully, ADSK will pick up... probably not.

Tell us how's it working out for you, it would been interesting to write a similar code. but not today 😊

[Sea-Haven]

Its like express tools in Autocad something like blockify would be added there. No express tools in Briscad the lisp is as source say extrim.lsp but has internal function calls so does not work in Bbriscad.

If you install the express tools on the BricsCAD app store would that resolve it? or just too different at the base.

Hey there,

I do a lot of bcad adaptation for lisp so am curious also.

I could not find the lisp in question though, can you point to it?

This whole exercise of entity pattern recognition can be handled really junky, or high quality.

Its similar to cleaning up GIS linework. You can handle tolerances, or expect exact numbers and that makes all the difference. Also, doing direct "compare everything to everything" does not scale well, so figuring out how to skip comparisons that will fail as matches is a big deal. Also multi-threading is so easy in .net that it always wins for choice of language. You program as if single thread, then switch a couple data types and the type of loop you run and it uses all cores.

Really, all companies in the cad use business should have at least 1 copy of acad and bcad. I especially like bcad for BPOLY use, it just works better and locks up less.

A quick answer Acad uses .Fas Bricscad uses .Des or if core program will be in a Dll. Had a look at Bricscad express can not be used.

It appears to be a core program.
