Attention All,

Source coding is now uploaded to the first post. This is an all entmake program. There are no command calls what so ever.

Unlike some of my past codes, I made extensive use of lists as well. Also I have done the images with Vector Image in a more effiecient way.

Again please review and let me know what you find.

Thanks,

The Buzzard

That is very generous of you Angelo (a.k.a. - The Buzzard). Thanks. Will give it a try upon my return to work on Monday.

Your very welcome ReMark,

I sometimes write this stuff just to pass the time. I always wanted to make a code for this, But never got around to it I guess. Codes that do alot more for your lisp dollar with one command is a neat thing. I remember spending many hours behind a terminal doing all this stuff from scratch and that was a drag. This is the type of code that can get use every working day of your job if your are in that field. I have been trying to find various diciplines to make a code for, But the research can take long to get the information one would need.

Anyway Enjoy and let me know how it goes.

I think the font choices are overkill, I prefer to use the drawing default font set by the firms standards. Unless there was a button added for this option?? other than that, love it. I guess we can hack it from here.

Thanks stevefr,

I see your point. Its the same reason I did not put layer color buttons in since anyone can set their own company standards in the source code. I did need something though to balance the dialog all the same. I thought about using OpenDCL for this dialog, But that is such a long process and most likely would frustrate others who are not familar with OpenDCL. There is quite a bit of choice just the same and even if you do not do HVAC the methods used here can still be a learning experience for one who may want to build a code for something else.

Since I was was going to make this code to control a standard, That would seem reasonable to have only one font style.

Anyway I am glad you like it.

Enjoy it.

Hey Buzz . Thanks . This is a nice one.

Hey Buzz . Thanks . This is a nice one.

So does that mean DCL is OK by you?

Just teasing Viv.

Let me know of all the quirks if you do not mind.

It only will make it better.

Enjoy the program.

February 7, 2010

Actually it is not ok you know that from my previous thread, :wink: because it increases your input time. But I think this one is worth trying. This program is for use with imperial units. Many companies like mine uses metric system. Can it also have a switch for imperial / metric.(i dont know wether it is possible or not). Another thing is about the fonts. I would like the program to use the default fonts which i am using in the drawing.

Thanks & regards

Hi Buzzard,

Nice looking program, I can see that you have put a lot of work into the DCL, with many options.

I hope you don't mind, but I have a few comments about the code itself, take what you like from them, but they are only suggestions.

-----------------------------------------------------------------

1. Why does the function 'RMD_SUS' have so many local variables when they are not used in this sub?

(defun RMD_SUS (/ [color=Red]ANG#   BF1#    BF2#    BFN$   BOFF$  CL01#  CL02#  CMT#  CNPT1# CNPT2# DCL_ID DCOL# DCOM$
                 DDEP1# DDEP2#  DEG#    DLEN#  DSYS$  DWID1# DWID2# EANG$ EDIR$  ELIST  ENAME  ERAD$ EXDR#
                 FSCL#  FSTY$   FSU$    INDEX  ITHK#  ITYP$  LATYP$ LCLR# LNAM$  LOOP$  LTYP$  LWGT# MPNT
                 MPNT1# MPNT2#  MPNT3#  MPNT4# MPNT5# MPNT6# PFN$   PT01# PT02#  PT03#  PT04#  PT05# PT06#
                 PT07#  PT08#   PT09#   PT10#  PT11#  PT12#  PT13#  PT14# PT15#  PT16#  PT17#  PT18# RAD#
                 SAM$   SIDE-a# SIDE-c# SUS    TANG$  TOA#   TOFF$  TSIZ# TSU$   TWF#   TXPT#  TXTA#[/color])

-----------------------------------------------------------------

2. I notice that you use a lot of Global Variables in your code. Just a suggestion, to avoid the use of loads of globals, just make one list that is global, containing all the values you want to store.

To aid you with an example if you decide to go down this route, I used this method in my Point Manager program:

http://www.cadtutor.net/forum/showpost.php?p=289563&postcount=1

-----------------------------------------------------------------

3. I tend to avoid the use of the (exit) function, I realise this is just me being a bit of a perfectionist, but you could avoid use of such by using a COND statement in your Dialog loading code, for example:

 (cond (  (<= (setq DCL_ID (load_dialog "RMD.dcl")) 0)

          (princ "\nDialog File not Found"))

       (  (not (new_dialog "MAIN" DCL_ID))

          (princ "\nDialog Definition not Found"))

       (t
          .. Now the program can start...

-----------------------------------------------------------------

4. To avoid repeatedly copying the headers for entmaking an LWPOLYLINE and such, I would recommend making a sub-function that you can feed a point list to, for example:

(defun mklw (l / e)
   (entmakex (append (list (cons 0   "LWPOLYLINE")
                           (cons 100 "AcDbEntity")
                           (cons 100 "AcDbPolyline")
                           (cons 90 (length l))
                           (cons 70 1))
                     (mapcar (function (lambda (a) (cons 10 a))) l))))

-----------------------------------------------------------------

5. Instead of tons of 'nth' statements, you could use just one 'mapcar' statement when using 'mode_tile':

 (mode_tile "SUPPLY"    (nth  0 CMT#))
 (mode_tile "RETURN"    (nth  1 CMT#))
 (mode_tile "DUST"      (nth  2 CMT#))
 (mode_tile "EXHAUST"   (nth  3 CMT#))
 (mode_tile "NONE"      (nth  4 CMT#))
 (mode_tile "INTERNAL"  (nth  5 CMT#))
 (mode_tile "EXTERNAL"  (nth  6 CMT#))
 (mode_tile "BOTH"      (nth  7 CMT#))
 (mode_tile "LEFT"      (nth  8 CMT#))
 (mode_tile "RIGHT"     (nth  9 CMT#))
 (mode_tile "90"        (nth 10 CMT#))
 (mode_tile "60"        (nth 11 CMT#))
 (mode_tile "45"        (nth 12 CMT#))
 (mode_tile "30"        (nth 13 CMT#))
 (mode_tile "SHORT"     (nth 14 CMT#))
 (mode_tile "LONG"      (nth 15 CMT#))
 (mode_tile "LEFT-OFF"  (nth 16 CMT#))
 (mode_tile "MIDDLE"    (nth 17 CMT#))
 (mode_tile "RIGHT-OFF" (nth 18 CMT#))
 (mode_tile "10D"       (nth 19 CMT#))
 (mode_tile "15D"       (nth 20 CMT#))
 (mode_tile "20D"       (nth 21 CMT#))
 (mode_tile "30D"       (nth 22 CMT#))
 (mode_tile "LEFTOFF"   (nth 23 CMT#))
 (mode_tile "RIGHTOFF"  (nth 24 CMT#))

(mapcar (function mode_tile) '("SUPPLY" "RETURN" "DUST"...) CMT#)

-----------------------------------------------------------------

All that is a can do. I thought at first about making it a combo Imperial/Metric program, But I was not sure on some of the metric standards. I stuck with what I knew and if someone wanted a metric program they could change it over easy. As far as the default fonts, I could eliminate the program making these and let the user set their own font style. Making it combo Imp/Met will require additional coding.

Get back to me and I can discuss with you all the changes you require.

Thanks for the input.

Lee,

As always you have the best ideas. I did take some of the past ones and put them to use. I like these as well. Please do not feel you are being too critical.

On the RMD_SUS Function, I had kept it separate from the Main Function to avoid having the program loop back into saving the variables again each time the program loops. The user settings would then be changed and I did not want this to happen. So when I delared variables local I just placed them there.

The other stuff you mention I shall fix accordingly.

Thanks for all this.

Not a problem, happy to offer my suggestions.

Regarding the localising of variables, the way I would look at it is to determine which variables are only referenced within certain functions and localise those within that function.

With the remaining variables that you have referenced throughout your functions, I would localise these under the main function, i.e. c:XXX (/ here)

But, really, whatever works for you, as long all variables (except globals) are set to nil after/before the program completes/begins.

That's funny, Because I can remember doing it that way a couple of years ago. I am not sure why I change that.

In anycase I will implement your suggestions some sooner and others later when I get a full understanding of everything I need to do.

I glad this program has some redeemable qualities.

While I was putting in the changes you suggested I got this strange error message.

Error:bad argument type: 2D/3D point: nil But heres a really great Llama!

Instead of an American Duct, I get an English Llama!

Thats Reg Llama of Brixton! I knew you were upto something!:lol::lol:

Attention All!

RMD is now revised to RMD_V1. See attachments on first post.

Also note that I remove all the multiple Font Styles and left Arch style in.

You can change this to your own default Font Style. Also if you wish to make layer and text size modifications, You may do so in this area of the code. Please also note that I will be coming out with a Metric version soon.

See below: Just change values where I had commented.

Error:bad argument type: 2D/3D point: nil

Which change caused this error? And what code did you use?

February 8, 2010

Looks great Buzz. I have a boat load of separate .lsp for HVAC that I need to add into one program (In due time)

Looks great! Once I get to work I'll give it a whirl.

Thanks

Lee,

You really need to put those math books down for a while when you cannot tell I am clowning with you.

The code is fine. I put some of your suggestions to work and its OK. I will get to the rest of it in time.

Thanks
