View 4 RepliesI have LWPOLYLINEs that represent a cross section of a train tunnel. Each LWPOLYLINE lists its 2D points in an Object Coordinate System.My task is to create 3D Polylines in WorldCoordinateSystem using those LWPOLYLINEs.I have posted a drawing with sample objects.
I have attached a sample drawing. Drawing was created with Civil 3D 2013, but I exporttoautocadr12dxf'd it and then save to 2004 dwg so most should be able to open it.
I am looking for an AutoLISP routine, which gives all aligned dimensions of a closed polyline, drawn in 3d.
I have attached a 2D drawing for reference.
Is there anyway to use LISP to list the x,y coordinates of a pline?

Can this be done?
I tried this:
(command "_.pedit" "m" ename "" "j" ename "")or (command "_.pedit" "" "j" ename "" "")
But it gives me an error something like this:
Requires numeric distance, two points, or option keyword.

I have this code to make fillet to a polyline, but the command does not allow specify fillet radius. How I can change the routine?
(defun C:filletv ( / ent ) (setvar "FILLETRAD" 2.500) (if (setq ent (entsel "
Select element near vertex: ")) (command "_fillet" "_P" ent) ) (princ) )
I have been using one routine very successfully to create a pline in modelspace that has the outline of the chosen viewports in the drawing. This one works great.
Now I am trying add other routines that I've done to better fit my needs. If I use each routine individually at the command line they work, but when I use all in a single command I got the following errors:
The routine SetColor - does not change color to Bylayer The routine RectWidth - ; error: bad SSGET list
Why?
See the attached file for more details and be free to improve whatever you want in my routines because they are very basic.
And, if I am not asking to much, is that possible to not be prompt to select objects? I mean, the routine could automatically select all viewports in the drawing...
I have plines of circuits that sometimes have T's (line goes along, then T's out then back to T point and then continues).
Here is example line -
(setq List_Pline (list (list 0 0) (list 1 1) (list 0.5 1.5) (list 1 1) (list 2 2) (list 3 3) (list 3.5 2.5) (list 3 3) (list 4 4)))
nth 0 = (0 0)
nth 1 = (1 1) - T point
nth 2 = (0.5 1.5)
nth 3 = (1 1) - T return point
nth 4 = (2 2)
nth 5 = (3 3) - T point
nth 6 = (3.5 2.5)
nth 7 = (3 3) - T return point
nth 8 = (4 4)
I need to be able to pick 2 points along the line and find the shortest route.
Examples -
1st point at 1,1 and 2nd point at 3,3 - new line is nth's 3,4,5
1st point at 0,0 and 2nd point at 1,1 - new line is nth's 0,1
1st point at 2,2 and 2nd point at 3,3 - new line is nth's 4,5
1st point at 3,3 and 2nd point at 4,4 - new line is nth's 7,8
1st point at 0,0 and 2nd point at 3,3 - new line is nth's 0,1,2,3,4,5
1st point is 1,1 and 2nd point is 1,1 - new line is nth's 1,2,3
I've tried using vlax-curve-getParamAtPoint, but it returns 1st T point.
Synopsis of program -
Select Pline
Pick 1st point
check if on line
Pick 2nd point
check if on line
check if 2nd point is before 1st point, if so swap locations
find last nth of 1st point
find 1st nth of 2nd point
return list
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 think I could do this using brute force, but would prefer a mathematical solution.
the resulting arc-fit pline has each pline segment converted into two arcs, the common radii of which are perpendicular to the original segment (unless direction of curverature changes)
the resulting arcs can be calculated given the angle of the tangents for each segment.
the factors for determining the tangents at vertex N are:
deflection angle at N
deflection angle at N+1 (90° or non-extant = not a factor, 0° or 180° = segment is the tangent)
deflection angle at N-1 (90° or non-extant = not a factor, 0° or 180° = segment is the tangent)
ratio of lengths of segments (N , N+1) and (N , N-1)
I can find the tangents when N±1 = 90° and when the segment lengths are equal but i can't figure out how to compute the tangent if these 3 factors are varied.
I don't want to use (command"._PEDIT" pl "_FIT""") because i need to collect the arc data anyway and at a high frame rate. The data will be used to further compute a spline frame that best fits a quadratic spline to the arcs. That part i know how to do!
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.
I need to change the color of all lines/plines that intersect a given pline. How would I go about making the selection set of all lines that intersect that given pline.
View 8 Replies View RelatedBasically I have one hatch pattern that was used at different UCS values. The hatch patterns are correctly shown on the screen as shown in the attached image. But the puzzling thing is that they both have a pattern angle of 0.
I have been writing a program that globally changes hatch patterns, but the problem is that once I update the pattern, they all have the same angle. I need them to keep their current rotation when the patterns are updated. I cannot seem to find object access to what that actual angle is.
vla-get-patternangle does not seem to provide the data I am looking for.
There are a ton of lisp to match text rotation to a selected line, but not vice versa.
View 9 Replies View RelatedI am having a problem with starts and ends of lines. I have draw two lines, end of first is start of second. The problem is because, (cdr (assoc 11 (entget line1))) and (cdr (assoc 10 (entget line2))), somehow, are not the same,
(= (cdr (assoc 11 (entget line1))) (cdr (assoc 10 (entget line2))))
is returning nil, what is so confusing to me is that:
(=(nth 0(cdr (assoc 11 (entget line1)))) (nth 0(cdr (assoc 10 (entget line2)))))
is returning true, the same is for y and z coordinates.
I need to check x y and z coordinates, for this type of problem...
ACAD 2009 on XP
Third party software installed which now causes AutoCAD 2009 to crash when a single key is pressed. We have uninstalled the software, however the editor is still looking for the
Non-existent ARX. This is the problem. What file or registry key declares the list as shown in APPLOAD? I have verified 2009 works in the administrator profile.
We also did a repair and then a reinstall of 2009 to no avail. What steps are needed for AutoCAD to build a profile when a previous profile existed?
can you start autocad with no drawing open ?
i would think that some type of script would work or could you change your target on a shortcut?
My first lisp, so bring it hard on me I want to be an expert in autolisp .
My lisp is meant to do the following:
draw a rectangle with ”0” fillet. It can be done either via rectangle command, or pline command. The attached lisp has the variant with the pline-case.
The, I need to draw inside a smaller rectangle, with a fillet value, that is promoted and indicated by the user. The smaller rectangle must be centered inside the bigger one. I thought it was a good idea, to take one insertion-point for the bigger rectangle.
and to calculate a 2-nd insertion-point for the smaller rectangle, via "polar" function.
What I get:
the 2-nd insertion point is put the same as the 1-st one.
I wish to draw the bigger rectangle with one layer "example: Layer 1", and the smaller rectangle with another layer "example: Layer 2".
Using Lisp or VLisp, how can I find the Start & End Point of an AEC_WALL ent. ?

With all of you fine teachers, I have the know-how to get the start and end values of a line.
Do you think there is a way to get a point returned that represents the true intersection of the two lines, without having to involke a user defined "getpoint" function using "intersect" osnap?
I want to create a segmented polyline with known angles / lengths, but I want to do this in 1 operation without having to copy/rotate/chamfer etc.
I'm sure it has something to do with UCS, but I've not used it in quite some time, I am stumped and everything I have tried so far has failed.
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?
View 2 Replies View RelatedIs 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)
