AutoCAD Visual LISP / AutoLISP :: Maintain View Distance When Changing Viewpoint?
Dec 30, 2011
I am using the following routine definition then calling the different view poins from a pop up menu.
Each time I switch veiw points it drastically zooms out. I would like to maintain the "zoom distance" if there is such a thing when switching views.
Ideally, like when in 3dorbit, I would like it to swing views around similar to that but to the defined viewpoints as below....
(DEFUN V (inp) (setq inp (strcase inp))
(cond ((= inp "T") (SETQ IXY 270) (SETQ FXY 90)) ((= INP "F") (SETQ IXY 270) (SETQ FXY 0)) ((= INP "RE") (SETQ IXY 90) (SETQ FXY 0)) ((= INP "L") (SETQ IXY 180) (SETQ FXY 0)) ((= INP "RI") (SETQ IXY 0) (SETQ FXY 0)) ((= INP "URI") (SETQ IXY 0) (SETQ FXY 45)) ((= INP "UL") (SETQ IXY 180) (SETQ FXY 45)) ((= INP "UF") (SETQ IXY 270) (SETQ FXY 45)) ((= INP "URE") (SETQ IXY 90) (SETQ FXY 45)) ((= INP "URF") (SETQ IXY 315) (SETQ FXY 35)) ((= INP "URR") (SETQ IXY 45) (SETQ FXY 35)) ((= INP "ULF") (SETQ IXY 225) (SETQ FXY 35)) ((= INP "ULR") (SETQ IXY 135) (SETQ FXY 35)) );COND (COMMAND "VPOINT" "R" IXY FXY) );END V.LSP

There are times that I have a really long curb polyline that has both line and arc segments. I wish to pick two points along that polyline and have it give me the distance between those two points along the path of the polyline.
Do we have this ability natively? Have I been missing something all this time? Normally I have to make a copy of the original entity, ... break, break, list erase or undo....

I would like to eliminate a mouse click in my program. I use getstring to allow the user to either enter in an integer or a distance used for labeling in a drawing, but I could eliminate the need for the user to then click an option that completes the label if I only knew how to determine if the entry is an integer (such as 5 or 15) or a distance (such as 24" or 36").

Let's say I have a 3D polyline, which I turn into a spline. I then want to determine how closely the original polyline and spline follow each other. How I can check this programmatically? The concern is to find the maximum deviation and its location.
Howto be able to run the check on other types of objects as well: arc, polylines etc.

I would like to write some sort of AutoLISP program to evenly space objects across a given distance. I have attached a .pdf file showing what exactly I mean.
I would like the program to enable me to either enter or measure (via the selection of two points) the "z" distance, to enter or measure the "y" distance, and to enter the number of objects, "n". I would then like the program to evenly space "n" objects across the "z" distance.
A program like this is, I have to be honest and say, way beyond my current capabilities.
Perhaps some initial guidance to get me going?

I have double line pipe drawings but i have to change distances between of this lines in entire drawing and i was thinking that maybe there is a lisp code which can create new double line according to my specify dimensions ...
example :
Distance between lines : 100 mm
------------------------
------------------------
here is what i want to do :
1. select double line
2. specify new distance ( for example 200 mm)
3. lisp will create center line middle of the selected lines ( maybe it can ask me that this center line will be permanently or not )
4. lisp will create new double line from this centerline according to my specific distance
5. new double line layers will be the same with selected old double line
and this lisp has to work for double arc or quarter circles too.

This seems absolutly silly.
(setq p1 (getpoint))
(setq p2 (getpoint))
(setq Dist (distance p1 p2))
Why does this not work?
I'm trying to build a command to replace AutoCAD's "DI" command, to give distance and delta x, y, and z values in decimal and imperial, and keep the angles in XY plane and out of XY plane.

I want to override the measurement in a dimension with a string of text using a LISP command.
E.g.. "select dimension"
type new text for dimension
replace dimension measurement with new text. I can get the entity and its values, buy not sure which value to change for the "text override".
BTW Acad 2012.

Can you change the color of a block attribute with lisp like you can with the built in Enhanced Attribute Editor function eg
I can change the value of the attribute LAMP but can I also change its color from the color of the layer its created on?
(while (not (equal ck "SEQEND"))
(setq e1 (entnext e1)
e2 (entget e1)
ck (cdr (assoc 0 e2)))
(if (= (cdr (assoc 2 e2)) "LAMP")
(progn
(setq e2 (subst (cons 1 lamp)(assoc 1 e2)e2))
(entmod e2)
(entupd e1)
(setq ctr (+ ctr 1))
)
)
)

I am trying to speed up some basic drafting of text revisions. In the P (plumbing) we call out the fixture units for a water pipe, along with the fixture units, the pipe size changes.
Is there any way to add numbers in an attributed block? (I have a lisp that works on text & mtext, but not attributes)
1.1. Example: Like if you have a block with two attributed text fields, the 1st field {x} is a number (fixture unit), and the 2nd field {y} is a number (pipe size). I would want it to only add the 1st text fields. [If possible then change the 2nd text field according to a changeable chart. (see #2)]
1.1.1. This is how the block looks like: x (y")
1.1.1.1. x could be any number from 0.5 – 10,000 (only using 1 decimal place, and only as needed)
1.1.1.2. y could be any number from the following list: ½, ¾, 1, 1¼, 1½, 2, 2½, 3, 3½, 4, 5, 6
Is there a way like in excel that you can set up a formula that will give a numerical result depending on other input? Like pipe size that change depending on the number of fixtures. There would need to be two different formula, one for hot and one for cold values (The value would be set at the beginning of the job; typically these values would not change later in the job). This could be separate text or if possible using the attributed block as described in #1.
2.1. Example: Like if you have a block with two attributed text fields, the 1st field {x} is a number (fixture unit), and the 2nd field {y} is a number (pipe size). I would want it to change the 2nd text fields according to the value in the 1st text field. If the value in {x} is 0.5 – 1.0, it would result in ½; 1.5 – 7.0 = ¾; 7.5 - 17 = 1; 17.5 – 36 = 1¼; ect.
2.2. In excel it would be =IF(x)<1,"1/2",IF(x)<7,"3/4”,IF(x)<17,"1",…{all #’s in between} …IF(x)>5000,"6")))))

Once upon a time in a job far, far away I had a lisp routine that deleted the current page setups and replaced them with new ones imported from a template drawing. It's probably been a good 6-7 years since I found it the first time.

I am currently using this lisp routine to export selected objects as a dxf to import into another program:
(defun c:dxf ()
(command "_dxfout"
(getfiled "DXF File:" "c:/dxf/" "dxf" 1)
"_Objects" (ssget)
"" ; completes selection
"_Version" "2004"
"16" ; non-default number or other option if desired, with followup line(s) if
necessary
)
(princ "2004 DXF Created")
(princ)
)
this saves the dxfs to a location of C:DXF
I would like it to save to a different location, the desired location is within the same root folder that the drawing is located in and is called "DXF-Programs-Releases"

What is the best way to change the color of two pieces of specific text in lisp? I want to change where it says (strcase ln6) & (strcase ln7) to the color of green. I tried it a couple of different ways but I'm having some trouble. First I am setting the current layer with a color of blue. I am then running the text command a couple of times. I want to run the mtext command a couple of times but I want the text to be green & I want the width factor to be .85

Any routine for changing color of AutoCAD background in model space. As for changing background color we have to follow four steps namely as follows:-
1. Execute OP
2. Go to display tab
3. Go to color tab
4. Change color
A tool that directly calls the model color shall be highly beneficial.

for my latest little project I'm trying to change layer settings depending on a entry in a sheet set attribute.
Basically, if the sheet set custom attribute entry is 'white' I want the colour of a specific layer displayed as 255,255,255, and if it's blue I want it changed to 0,0,255. So I can control the colours from a sheet set custom properties level.
And for it to check if the layer existing in the drawing, so it'll skip the process if it's not there.

The following snippit of code is changeing the color of text in a cell of an AcadTable. It will set the color to an RGB value and works great. But what if the color is a normal color 1 through 255 from autocad's pen table. How would I set the cell text color?
(setq objColor (vla-getcellcontentcolor eVLAMT R C)) ;sets a Color Object, whatever that is
(vla-setrgb objColor RED GRN BLU) ;sets the new color of the Color Object
(vla-setcellcontentcolor eVLAMT R C objColor) ;sets that new color object to the cell

Is it possible to obtain a list of coordinates for view ports (with dxf codes or otherwise) similar to obtaining a list of (assoc 10) for polylines?
I'm aware I can get the center, width and height from the dxf codes, but what about for clipped view ports with irregular shapes?

I am having trouble moving an object a certain distance. The distance is defined by a pre-defined variable. I just can't figure out the syntax for the autolisp command.
Here is the bit of code if written, there is more code not shared here that defines the points for the polyline .
;-- the varaible box_height is defined earlier in the routine
;-- Draw the polyline for the top of the cabinet
(command "pline" p1tt P2tt P3tt P4tt P5tt P6tt P7tt P8tt "c")
;-- Assign the new part a variable name
(setq cab_toppl (entlast))
;-- Extrude the polyline to make the top of the cabinet
(command "extrude" cab_toppl "" cab_intw "0")
;-- Assign the new part a variable name
(setq cab_top (entlast))
;-- Rotate the top of the cabinet down to the floor of cabinet
(command "rotate3d" cab_top "" 2 p1tt p2tt 90)
;-- Move the top of the cabinet to the final location
;-- HERE IS THE PART I'M HAVING TROUBLE WITH. ESSENTIALLY ONCE THE PART IS CREATED I'VE NAMED IT CAB_TOP AND AM NOW TRYING TO MOVE IT IN THE Z AXIS THE DISTANCE DEFINED BY THE VARIABLE BOX_HEIGHT WITHOUT USER INPUT
(command "move" cab_top "" "0,0,0" (list (0 0 (box_height) "")
;--THIS PART IS OKAY
(setvar "CLAYER" oldlayer) ;restore active layer
(setvar "BLIPMODE" 1)
(setvar "OSMODE" 135)

I have created a bunch of templates (title block type drawings) for my company. In these templates there is a dynamic block used for a particular note. Based on customer number, this note will be changed.
We have a program that will insert the correct template based on the drawing type. It will know the customer number and change the dynamic block visibility state to reflect the correct text in the note.
Here's the problem; I don't know why, but sometimes the visibility state does not change. It's not the code as it works just fine in some drawings.
I've gone in and just changed the visibility state name, then changed it back, then saved the drawing and it worked. In some cases, I've also just gone into the template and deleted the dynamic block and re-inserted it, and it began to work again.
Having trouble with dynamic block visibility states not working when using an automated process?
