AutoCAD Visual LISP / AutoLISP :: How To Raise Or Lower Z Value At Any Vertex
Aug 23, 2012
I am using acad 2010. I have the ability to draw a 3d polyline on the screen with a different xyz value for each vertex using a digitizing puck. I need a lisp routine that will allow me to adjust the z value only (not the x and y values) on any 3d polyline. I just need to raise or lower the z value at any vertex and repeat if nessasary but I don't want to type it in, I want to raise/lower the z using digitizing puck (with z wheel)....example: I draw a 3d polyline which has 9 vertices with different elevations - vertex #6 is 22.6 (too high) in the z value so I need to drop it to 22.4 without typing it in. Vertex #8 is 12.2 (too low) so I need to raise the z to 12.6 without typing it in and using the z wheel on my digitizing puck. Others have tried and but this is a bit complicated and I may have not expressed it correctly.
I need to wright a routine in autolisp that selects all 3Dpolylines with the same vertex Z value.Qselect as no transparent mode and filter doesn't work.
I have been having a few 3dpline's with the last vertex being in a different layer. I saw a site mention that this is an AutoCAD 14 bug that could be caused if a program does not end the pline with the layer being set properly before doing a seqend command. If I move the entity to another layer and then back to the correct one it will fix it. Audit in R14 will not show any errors. If I export the file to AutoCAD 12 , audit will detect and fix the problem. I would like to find a Lisp, ARX, etc. that would check for this problem and fix, change color or layer, or whatever.
I have a program that makes 3d polylines from various data. That 3d pline then gets added to a civil 3d surface as a breakline. I want to modify the pline with my program, but preserve the handle, as I think that is what C3D uses to decide if its part of the surface. I tried this as a sample with no luck:
;DELETE 3RD VERTEXT FROM 3D PLINE (DEFUN C:T3 ( / EN ENAME ENT ENTL) ;GET 3D PLINE (SETQ ENT (ENTSEL " Select 3D Pline:")
[Code] .....
I know you can modify a vertex, but what about add and delete with entmake and entmod? I also considered using activex for this task, but you can only add verticies from what I could tell in the object browser of VBA, not delete them.
What I will be doing is deleting all the verticies and adding back the correct ones. Or if there was a way to transfer a handle to a new entity after deleting the old, that would suffice too.
In VSX4, when laying a background music track for a project, is it possible to raise and lower volume of sections of the track along a continuous track of music?
Is there a lisp that will allow me to do a continuous dimension, but will alternate the dimension position from low, high, low and high? If there is no lisp already created, how to create one?
See Continuous dimension attachment for example.
I work at a glass and glazing company and this is how we dimension mullion width and DLO. See typical window dimensioning attachment for window elevation with dimensions.
I have a list ("temp.dwg" "temp2.dwg") and would like to add the string "insert text here" into each item in the list resulting in ("insert text heretemp.dwg" "insert textheretemp2.dwg"). how would i go about doing that using LISP?
Is there a way to programatically set a visual style before a drawing actually opens?
We have some huge models and people seem to forget to change their visual styles back to 2D wireframe before saving and exiting drawings. Some models will crash on some workstations when trying to open in a rendered mode.
I found a lisp with a function that looked to set viewport visual styles. But it does not seem to be supported anymore. --> (vla-put-VisualStyle vport 1)
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.
Lisp that switches back on Selection Preview i.e. thickens and highlights lines when you hover over them?I don't know why, but they are always unticking the boxes.
Is it possible to execute a certain command based on multiple selections withinin a dcl? for example: two radio colums, one with selections A and B, and a second with selections 1 and 2. is it possible to program commands based on user selections from each column? ex: if A and 1- do a command. A 2- do a different command, etc...
I tried :
(action_tile "key1" "(setq A t") (action_tile "key2" "(setq B t")
I am trying to find a lisp that would get an attribute value (tag name = NBR_5) . I'm trying to run a simple routine that would let the user place the value from the titleblock attribute as text on a drawing. I see a ton of articles regarding getting attributes but I am not well versed in programming.
I'm trying to find acceptable point values to feed to the vlax-3d-point function for a vla-addmtext function. With vanilla lisp I just provide the point as x y = "7/32" "2-3/8". So I assumed that I could drop a 0 in for the z like: (VLAX-3D-POINT "7/32" "2-3/8" 0).
Then I thought I was going to be tricksy and try (vlax-3D-point (getpoint)) believing that I could pick the point and get what I need to feed the function, but yet again, no deal. The command line gave me:
node of #<variant 8197 ...>
Nothing I can use in my code. So how do I find the point in a format that vlax-3d-point will like?
I use Spell Check regularly and I always check the entire drawing. I would like to add to the Spell macro so that when I pick Spell from the toolbar it goes past the Check Spelling window and begins checking the entire drawing.
I believe I need to insert Alt S into my macro to select Start from the window to begin the check. Is there a character or series of characters that will represent Alt in a macro?
I upgraded from Autocad 2004 to 2012 recently and my lisp file doesnt work anymore.
what it's supposed to do is when looking at the layout tab that you want you can switch to the model space location of the same zoom as the layout tab without messing with the layout zoom.
I need a program that simulate this DOS command: dir /on/b *.dwg >list.txt
it list all dwg files on current open dwg file folder and sort them and finally put them in a text file with list.txt name. something like thistype list.txt)
(sort alphabetically and logically) because of disabled DOS utility in my PC I need a pure lisp functions, I tried to wrote this program but I couldn't!!
Instead of starting an application, how to shut all of its instances down. Let’s say I have iTunes and/or Internet Explorer w/ a few tabs open and I can close them down without getting to the application to terminate it the usual way.
I am trying to get my original layer and lintype reinstated after the user is finished with the pline..I know Im suppose to use the while command but am now completely lost on which way to do this
I have a drawing that has 2D pipeline (only x and y, z value =0) and 3 topo contour lines ( with x, y and z vaules). I need to divide the the 2D pipeline into say 2000 points and then get the corresponding z values from the topo contour lines. I think it can be done by interpolating between the z values for the two apparent intersection points of the 2D line and the contour lines, the x and y values will be the same for the points that falls between these two aparent intersections. Is there any lisp out there that can do that.
Is there a way to find the name of the second folder?
Is there a way to find the name of the third folder?
The string length of the characters for each of the first, second, third (and so on) folders are different, which means I can't count character using the "substr" function.
I have to go into approx 600 3D Models and rotate them all by 90.
I've just tried to search for a lisp that will do this to all of these files in one directory and can't find one. Something that will do this and save loads of time. I need to do this tonight so that these MEP files will all be ready for tomorrow morning.
