AutoCAD Visual LISP / AutoLISP :: Close Polyline To Wipeout That Not Made Of Straight Line Segments

Oct 31, 2013

How can I draw a wipeout matched with a closed polyline?

in the other word, a lisp program that prompted for a closed polyline and draw a wipeout by selected polyline.

AutoCAD Visual LISP / AutoLISP :: Select A Polyline That Will Either Be Straight Or Contain Bulge

Aug 5, 2013

I would like to select a polyline that will either be straight or contain bulges and offset lines either side of it a prescribed amount, I have tried a couple of options that don't involve picking points on both sides to no avail.

AutoCAD Visual LISP / AutoLISP :: Reduce Polyline With Multiple Vertices To Single Polyline

AutoCAD Visual LISP / AutoLISP :: 3D Polyline To Polyline To Spline With Max

Sep 21, 2013

Due to modeling purposes, I need to convert a 3D polyline to a spline. What I have been doing is:

- change polyline fit/smooth to cubic from properties
- convert polyline to spline by typing spline -> object
- method -> fit from properties

You can see the original 3D polyline (green) and the resulting spline (magenta) in the attached drawing.When I zoom in and measure the distance between the two entities at different points along them, at some points the perpendicular distance exceeds 5 millimeters, and I want to ensure the deviation remains under 1 millimeter or even less.

I know I can change the knot parameterization of the spline, and this does work at some locations, but the difference increases at others.Why is there a 5.6 mm difference between the spline fit point and 3D polyline vertex, as measure in the attached drawing?

Now, I can go and manually stretch the fit point to coincide with the vertex. Also, I can add fit points between existing ones to drag the spline closer to the original 3D poly.

However, some of my polys are really long, and it is very time-consuming to do this manually while measuring points along the entities to make sure the distance stays small enough.

how to automate this process? For example a lisp that would maybe take the original vertex points, add say maybe 3 (not too many) new ones between them, and then generate a spline while making sure the deviation is less than the set value of 1mm? I am using AutoCAD 2013.

AutoCad :: How To Not Make Curved Line Break Into Straight Line Segments

Jun 27, 2012

I draw a curved line and would like it to remain as a curved line even after saving the file. However everytime after saving, and opening the file again, the curve breaks into many line segments, which is not what I want! I want the curved line that I draw to remain as a curved line even after saving and opening. How do I do that? I am using autocad2010.

I use the ARC command to draw a couple of lines, they look okay here. But after I saved it, and re-open it again, what previously appeared as curved lines changed in their appearance to polyline segments.

AutoCAD Visual LISP / AutoLISP :: Don't Auto Open Or Close Dialogs

May 30, 2013

Is there a way Autocad could just do what I asked for, and nothing more?A few examples

- After publishing, the publish dialog auto closes.  I don't wat that.  After publishing dwf I also want pdf.(I know you can save the list, that's not the point.  If you didn't close the dialog I wouldn't need it)

- When selecting a hatch, the ribbon automatically jumps to Hatch Editor.  I don't want that.  Maybe I just want to change the layer.  I can find the Hatch editor my self..Dito for XREFS

- I do not want any dialog giving me warnings, about anything.  

If an XREF doesn't get attached, I can see that.  I don't need a dialog telling me.If a shape file is missing, I can see that..A triangle sign above the command line is totaly adequate.Don't auto open or close dialogs, for what ever reason.

So ... don't auto do anything I can perfectly do manualy.  No doubt there are a few more examples I can't think of right now.The nice thing would be to get a variable that gives me that "no auto" mode.

AutoCAD Visual LISP / AutoLISP :: Change To Layer 0 On Exit / Close

Feb 25, 2011

I am using 2011 Civil 3D and there is a bug I am trying to get a workaround for. If your drawing is not closed with layer 0 being the current layer several different civil 3D entities assume the color of the current layer of xref'd drawings.

From my reading it appears I need a reactor to thaw layer 0 and make it current before close or exit commands. I am not a programmer and have struggled making this work.

AutoCAD Visual LISP / AutoLISP :: Change Z Value Only On 3D Polyline

Aug 23, 2012

I am using acad 2010. I have a contour generator that uses 3d polylines to make contours. I get depressions or tops where I don't want them. I need a lisp routine that will allow me to adjust the z value only on any 3d polyline. I need to raise or lower the z value at any vertex and repeat if necessary. I don't need to prompt the user- I am the user.

AutoCAD Visual LISP / AutoLISP :: Set Polyline Elevation

Jul 19, 2013

I create contour line in TOPOGRAPH program, and I import these polylines to AUTOCAD. I have to set elevation for each polyline manually, and I waste a lot of time doing that.

So looking for lisp doing that automatically. I mean, invoke the command, set the first elevation and them select the polylines.

e.g. The first elevation is 530. The next polyline that I select is 531 and so on.

AutoCAD Visual LISP / AutoLISP :: Region To Polyline

Feb 17, 2009

For the sake of editing, I sometimes make LWPOLYLINES and convert them to regions so that I can union and subtract and intersect, etc.

then sometimes, like now, I want to work with them like as LWPOLYLINES again.

is there some command I don't know, or some routine or shall I make one?

AutoCAD Visual LISP / AutoLISP :: Polyline Width And Fillet

Feb 5, 2013

I've been searching on and off all morning for a lisp routine, without any luck. I'm trying to draw a pline with a pre determined width (5") and be able to draw unlimited line segments then automatically fillet with a pre determined radius (5").

I wrote this generic macro: ^C^CPLINEWID;5;PL;\\;FILLET;R;5;F;P;LAST;  to save SOME time but I want unlimited line segments. Can this be modified or would a lisp be the better route to go?

AutoCAD Visual LISP / AutoLISP :: Labeling Polyline Areas

May 4, 2011

Code below, for labeling polyline areas

It works great for what i want, with 2 exceptions the text is to small and the label is not inserted at the centroid of the polyline, rather it is placed outside the polyline.

i am able to increase the text style by adjusting the dimscale before i run the command, however it would be good if the program could do that automatically, i would like the text to be about 300 units high, and for the label to be placed at the centroid of the polyline

do you know command or lisp that will do new pollyline between two polyline on 1/3 or 1/4 space between them.

I need sommething that would be faster,know is use measure on pollilines then i draw between horizontall polylines on verteks or point new pollyline and then divide it on 4 or 3 parts.

AutoCAD Visual LISP / AutoLISP :: Vertices Of A Polyline Segment

Dec 18, 2011

I have to intersect polylines "POLYLINE" and "LWPOLINE" with a line and get all the angles of all segments of the polyline that are intersected.

To do this I used a loop that monitors all the vertices of each polyline to find the two vertices of the polyline segment that intersects the line. Unfortunately, these polylines have thousands of vertices and the processing done in this way takes too long.

With the vlax-curve-getClosestPointTo I could very quickly find the vertex of the polyline closest to that intersected with the line, but I need to find the other vertex of the polyline segment to determine the angle of this.

Another question: is there a quick function that returns the exact point of intersection of two curves (e.g. A line and a polyline, or a line and a circle?

AutoCAD Visual LISP / AutoLISP :: Angle Of Polyline Segment At Specified Point

I am writing a routine that will place a piece of text at a specified point along a polyline. My problem is to determine the angle for the text. It needs to be the same as the segment of the polyline that it falls on. Just can't get my head around how to get that angle?

I can get a list of the vertex point of the polyline, but how do I determine the segment the point falls on?
