Need better multiline

January 6, 2007

Got any good beginner tutorials around here? I'm not a stranger to programming, I know Visual Basic, some Java, C concepts, PHP, so I should be able to jump right in.

Free time is the problem for me too. When I have some, I'll look into it. In the mean time, you can check this:

Now pipes is multilines and coners is closed polylines. But change widths within the command while unavailable. It so is important? Possible to repeat a command with new width? It's possible but I had small time to do it.

Hi.

Nice lisp, ASMI. ¡Thank you!

See you.

January 8, 2007

Attention. To function c:dpipe are made some changes. Namely removal of a polyline after pressing Esc button.

>jademar

Thank you.

Hi ASMI, the script is looking good.

Yes I can always start a new command with a new width. But that is what I use mline for now anyway. I'm trying to save time. So changing width inside a single command would save a lot of time.

Thanks for doing this!

>Vigilante

In some drawings is problem with "flying" coner polylines to 0,0 coordinates. I work to fix it and adding wide change inside command.

January 8, 2007

Vigilante, are you doing Ductwork?? or something similar that has transitions?

if so then ASMI, this is what he's wanting.... say you pick a "pipe" or "duct" that is 12" wide. well, within the command you have written, (assuming of course) he is wanting to choose a different size, bigger or smaller. so from 12" to 8", there will be a gap between the two sizes, connecting the plines together and showing caps. basically, it will transition to a new size all in one routine, on the fly. attached is an image to help clarify.

January 8, 2007

Oh and thanks for the link, Paul. I need to start learning this stuff. I'd like to merge some features of both yours and ASMI's script.

I'd like to eventually have a multiline command for drawing our ducts so there is basically no after-work to do. That would be more than awesome!

January 8, 2007

Ya, that is pretty much it, it's air duct.

I've attached a couple images to show kind of what ours looks like, and what I'd like my dream command to do.

duct.jpg is an image of what I'd like the command to be able to do in one fell swoop.

duct2.jpg is an example of a job I recently did.

Now imagine how much time could be saved on that job if I had a faster way! Imagine that I had to draw every arc manually, and every transition. That is a lot of exploding, trimming, drawing, stretching, texting, capping, and more!

Just by giving me rounded corners, you have saved a lot of time!

January 8, 2007

Vig... i work at a commercial HVAC mechanical company so we draw the same things.

if ASMI wants to basically write the whole program for you, then hats off. however, there are definitely alternatives. for instance, you can go to www.caelink.com and check out their HVAC package that your company can buy that does everything on the fly, or start utilizing Blocks for your vained 90's with the MLINE command. ASMI has already done what's needed for the radius 90s. really the only thing i have to do is add my transitions, which isn't hard at all if you use the OTRACK option from Midpoint of the last drawn duct.

also, with Tool Palettes, you can add ASMI's Lisp routine as a button. then copy/paste it many times, renaming and using Macro's to resize the "duct" so you don't always have to draw it.

for instance: i have utilized ASMI's lisp on a Tool Palette.

next, i copied/pasted each one, going to the properties and changing the Lisp using Macro so all i have to do is select which size i need. if you look under the 'Command String' i have renamed ASMI's Lisp to "db" instead of "duct" for my own personal custom keyboard command. so when i select the icon, it starts the Lisp. Then, using Macros, i use ";" = enter, and then i type the offset, and bam - instant duct sizes at the click of a button all within 10 minutes of setting up and planning ahead.

ASMI's Lisp does the rest, except transitions, but it's really easy when you Offset the next ductsize by using OTRACK from the midpoint of the endcap. just PLINE the three points after you're done with the entire duct trunkline.

>Vigilante, StykFacE

Hi. I can do, what you ask me. But I have much work at this time. My cheef goes behind my back and see how I work . But I find some time at this week to end this lisp.

January 9, 2007

well, i'm perfectly fine with what you have done already. of course it would be awesome to have a completed Lisp routine that fit's our exact job needs.... that is completely up to you. i'm in the process of learning Lisp myself, i know VERY basic things.

i just really appreciate your work so far. i have already been much more efficient at the office with it, especially on radius ductwork.

January 9, 2007

Yes, excellent so far!

Thanks for the suggestions StykFacE. I've always been faster just wacking shortcuts out then trying to use menus and blocks and scripts and so forth. But I'll give it a shot with the macros and see what happens.

Cheers!

January 10, 2007

well trust me, i'm ALL ABOUT the keyboard. i HAAAAAATE seeing people use nothing but the toolbars, but in this case it's actually faster. for instance, i have my MLSTYLEs saved as a block so when i import them in i have to type: ML Enter, STyle Enter, ## Enter, then draw the duct. better just to click a button and voila - done.

same with the Lisp. it's just better in my case.

January 24, 2007

Now pipes is multilines and coners is closed polylines. But change widths within the command while unavailable. It so is important? Possible to repeat a command with new width? It's possible but I had small time to do it.

Hi ASMI, yes I would still like to change widths in the command, this would be the ultimate feature!

Just checking in.

Thanks again!

January 24, 2007

Yes I remember. I shall be engaged in it today. I all time on what that distract and for it there is no time to finish. It is necessary to be more concentrated... and to not distract on writing other programs.

January 24, 2007

Thank you for doing this, I am sure the finished script will be most useful to anybody who has to draw air duct like this!

January 27, 2007

At last the trial variant is ready. It demands additional check. It works as drawing of a usual polyline with various width of segments, option Arc does not work.
