AutoCAD Visual LISP / AutoLISP :: Larger Routine To Create And Rotate Text Based On Object Selected
Dec 29, 2011
the expression in question is part of larger lisp routine to create and rotate text based on the object selected and the viewtwist variable (we use dview twist to rotate our views when needed)
So the expression in question:
(< (/ pi 2) ang (* pi 1.5)
where ang is the total angle used to determine proper rotation of the text.
Now the problem. In most cases where ang = 90 (or 1.5708 radians) this works fine. the two exceptions i have encountered
in testing are a line at 70 degress, viewtwist 20, and line at 50, viewtwist 40. For whatever reason at these two conditions the expressoin evaulates True instead of nil and rotates the entire text object incorrectly (180 degrees). So question is how exactly is this being evaluated? i know its comparing ang (* pi 1.5) to (/ pi 2). is there some sort of rounding error? or maybe the expression needs a wee bit more definition? attached image and full lisp routine for reference of what is happening, blue text is angle of the line as created by routine at viewtwist 0.
I was wondering if there is a setting somewhere that could hold my snapmode settings after I use a lisp routine. I found a lisp routine to rotate text and have noticed that everytime I use that lisp command I lose my osnap settings....
lisp routine that will add together the values of text entities? For instance, if I have a big parking lot and each section is labeled with the number of spaces, I could pick the texts and it would add all the numbers together to give me a total. Right now I export to excel to do this. I have quite a few situations where this would be handy, not just for parking spaces, so I really just want a lisp that will add all my selected numbers.
make a LISP that will work with my room dimensioning? I'd like to be able to specify the width and depth of the room using a command similar to the "dist" command, and then click a point to place a text based on the distances gathered. I'd also like the text to be formated into architectural units and displayed like this: 12'-0" X 13'-5". Also, if possible, round the result to the nearest inch (to avoid 1/2" and 1/4" dimensions).
I was interested in finding out if it's possible to write a LISP routine that would execute a pop-up dialog box say every 30 minutes. This is strictly for ergonomic reasons to remind the user to take a pre-determined break.
I am not an expert code writer by any means, but I imagine the routine would autoload and resetting the timer to 0 upon opening a particular drawing file. The LISP routine would then run in the background and run the (alert "") command when the timer reaches 30m 0s. When the user presses the OK button, the timer resets to 0 again.
I am looking for a way to extract (filter) all polylines, and loop a lisp based on the number that are found within a "W" selection window.I am frustrated getting "malformed list" or errors, even after defining "n" for repeat.The code I have so far looks like this:
Without the (repeat () portion, it was working ok with selection window, however it only would run the commands for a single polyline. What needs to be done without overhauling the code? The lisp has worked on a drawing-wide basis, however needs to run on only on user-windowed polylines since there are other polylines within the drawing which are attached to layouts via viewports.
Create a routine that looks for a block based on a portion of that block name, using a specified path or search path.
For example, block to search for is BLOCKABC123, so if someone inputs ABC or 123 as a block name, it will locate that block within that folder and inserts it into the drawing at a user specified location.
Ideally, if there is a check in that if it finds more than one match, then perhaps it flags or prompts you to choose 1, 2, or 3 option which block to use. But I can live without this special function if it requires too much time to code.
For a program i am working for i have to extract the base point of a dynamic block.
This can be done perfectly by this function:
(cdr (assoc 10 (entget (car (entsel)))))
But i want the entity selected based on a previous slected point. So for example when i selected pt1 (which is a point at the border of the dynamic block) i want to be able to extract the base point on the block whit this point.
I am looking for a lisp routine that, when activated, asks the user to select the "preset view" (similar to the preset view command found in the ribbon, but instead smaller and quicker), enter name for the view, end.
If possible, perhaps a command, relating to the routine above, that can be placed in the short-cut menu (right-click), which will list the preset views (made by the user), and be selectable.
The approach is instant view change, where it is possible to apply the command, then reapply to go to another view.
if possible, surely there'd be some people that may be interested in this capability.
Any Lisp Routine to scale text objects a certain value and have the program actually scale each text object as you pick them.
The change text height using the Properties function does not work for what I need because the objects I need to scale are Mtext objects with Background Mask, and when you use the Properties function to change their text height it messes up the background mask so that you have to select each text entity and stretch the mask area smaller or larger, but if you use the scale function it scales the background mask as well so the background mask coverage is still the same.
I thought this would be a simple tblsearch process, but as far as I can tell, there isn't a tblsearch symbol table for vplayer settings, so I need to get more creative I guess.
I want to be able to get the vplayer color of a selected object as part of a larger routine I'm putting together.
Is there a way to determine the type of ACAD object that the user selected? I need to retrieve the value from either a dimension or text. The info could be in either format so the lisp routine needs to determine what was selected so the correct vla-get command is used.
Once I determine what the object is I can use an if statement to retrieve the value.
;user selects the object (setq dimobj (vlax-ename->vla-object(car(entsel)))) ;If ACAD object is a dimension do this. (setq dimvalue (vla-get-textoverride dimobj)) ;If ACAD object is text do this. (setq dimvalue (vla-get-textstring dimobj))
I need a lisp file that can read the total length of selected object (lignes, polylines) and summarize them by layers or by color in a table
e.g
command:tl (total length) select objects found total length....... select object (Ent) total length or [Add/Subtract/Table] : total length = ....... if table Enter an option by [ Layer/Color/line Type/line Weight] <layer> :
I would like to use the entmod method to rotate the text in a Multileader object. Reading the DXF code tells me the dotted pair of 42 seems to be the rotation angle, but entmoding that does nothing. Obviously I don't know how to modify this complex object.
A program that prompts:"select objects:" then I can select some objects like as text, line, circle,... after that program find all texts in selected items and swap text
swap means: xxx/yyy ===> yyy/xxx ; "/" is a divisor
I’m trying to put together a loop for if nil or something other than text or mtext is accidentally selected than prompt text was not selected. This is what I have so far.
I have a little routine to add two selected numerical texts together and show the result at a selected position. I am using the entsel method to select them. I would like a way to highlight the selected text temporarily. Is this possible. The routine is as follows.
(defun c:T+ ( / Txt1 Txt2 Txt3 Pkt ) ;Adds second selected number to first (setvar "dimzin" 3) (setq curlay (getvar "clayer")) (setq curcol (getvar "cecolor")) (setq curlin (getvar "celtype")) (setq ds (getvar "dimscale"))
I'm trying to write a lisp routine that, when I invoke the mleader command, osmode is set to "nearest" & orthomode is set off. I then would like the original settings to be returned.
I have very little knowledge in complex Autolist routines and routine to do the following:
I would like to be able to provide a Prefix and/or Suffix via dialog then pick any line of text or multiple lines of text and have it concentrate. For example: Prefix: First Floor Suffix: M100. I pick the room text on an arch floor plan "Mechanical room" and the second line "100" The result will be "First Floor Mechanical room 100 M100".
But lets take it a final step further; once condensed, I want it added to a perticular tag attribute in a block I inserted.
Example of how I would use it. I insert a symbol for an addressable smoke detector that has several tags; one of them being Location. I would use this routine to gather the information provided by the Arch floor plan and join it with the block attribute for exporting later for use in the Fire Alarm Panel Programming.
