Hello, is there any way to automate this process? I have provided a simple example, but my projects consist of numerous lines like this, which need to be trimmed using the "trim" command. I would like to know if there is a way to automate this, through a macro or LISP.

Thanks.

FENCE selection might help?  Maybe put in a CUI macro...

[leonardohs1104]

how do i make a fence selection? after select, my F command is "Fillet"

[jskalaXDDX5]

Try TRIM Enter FENCE Enter...TRIM command seems like one that has been updated lately...maybe check back through the Forums or browser search for latest info...

I use peripheral with Macroworks 3.1  Macro with that looks like this

The two Enters after TRIM works as Select ALL, I think...I am using 2023 so again the TRIM Command may have changed recently...

You can type F instead of FENCE

[leonardohs1104]

I was able to access the "FENCE" command, but it's still not what I need. We work on drawing cities, and when we start designing them from scratch, the initial aspect looks like this, as shown in the image below. Executing the "TRIM" manually takes a lot of time. The solution would be something automatic to trim only the small quadrants. I'm not sure if it's possible.

@leonardohs1104 requires LT 2024+

the code provided on this website does work but requires you to select each intersection one at a time

@leonardohs1104 Since it looks like one, why not use a custom hatch pattern with that look instead? All you need to know is what all those dimensions are to be.

[leonardohs1104]

@paullimapa ok, i will analize, thanks for your time.

@pendeanthis drawing was a simple example, but is not perfect quads hahaha, here in Brazil, the streets are irregular, so, i think custom hach is not recommended for me, but thank you for your opnion

Look at CAB's Breakall.lsp will do what you want, BUT a big but may not work with LT25.

Once you break all you can find the short lines and delete them yes I know it works used in concrete slabs. 

Please test and let us know.

@Sea-Haven, i wanna do like this video https://www.youtube.com/watch?v=swwDirFKB9o

but i can't dowload this plugin, the company dont give me this access

Looks like you could just use a rectangular array instead of drawing lines and trimming to me.

[leonardohs1104]

No, because this example there are perfects rectangles, but in real life, is no like this

The image below, is part of a city that i am working right now, i've finished the drawing, but i've trimmed all the corners mannually

So your latest image is not perfectly sharp corners (nor do you want them to be if you create city street maps app day): what radius are you going to look for and need? Otherwise you'll be manually creating them in which case the last lisp offered is as good as it is going to get.

I've only highlighted a few of the many choices that need to be made

[leonardohs1104]

So, like the video link I sent, cutting the crossings to create the corners would be the first step. After that, the next step would be to round the 90° vertices. So, the primary need would be this, and then possibly an automation to round them as well, but that would be another case. The last LISP offered only breaks the polylines, which isn't very useful for me, since cutting the intersections already results in them being cut.

Regarding the highlighted cases, it wouldn’t necessarily need to cut them, as I can do that manually since they are occasional cases. The biggest help would be to cut most of the corners.

[Sea-Haven]

You say can not download then how do you expect to get a solution ? Does not make sense. Breakall works great.

Executing the "TRIM" manually takes a lot of time. 

I know this is not what you are hoping to find, but if you can't find it, or in the meantime if you are stuck doing things manually you could at least cut down on keystrokes...

*^C^C_TRIM;;FENCE;\\;;
*^C^C_FILLET;FENCE;\\;

From the CUI, Commands repeat, TRIM multiple intersections at the same time, can only FILLET one corner at a time, but once one is in the Command it's just Mouse Clicks...FILLET macro could be expanded to specify radius...

I would again suggest peripherals...below is FILLET...with TRIM above one would end up with six keystrokes max per intersection...nowhere as cool as the LISP so I hope you find what you want...

[leonardohs1104]

did you guys saw the video i sent?

[jskalaXDDX5]

did you guys saw the video i sent?

Yes.  The video looked like an advertisement for a Plug In...or Dramamine...or both.  The end result looked pretty cool though and if that is what you really want you might consider asking whoever made the video...and the Plug In...

[leonardohs1104]

Yes, the problem is the company dont let me install external plugins, but, apreciate your time spend. Many thanks!
