Dec 18, 2011I 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
Mar 19, 2013I 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?
AutoCAD Visual LISP / AutoLISP :: Convert Ellipse Segment Into Spline Or Polyline
May 3, 2012Our customer send us drawing with ellipse segments into.
With Autocad 2008 I bought a plug-in call SplineConvert that did the job perfectly but not compatible with 2013.
Is there any plugin that could replace that tool ?
Is there any standard ACAD command that could easily do this Job ?
I need a way to make 2 or 3 times per week this converting on all ellipses of large and detail 2D drawings so no time to offset in and out all those .
I try also DXFOUT in R12 but all the spline are being converted into 3d polyline making a huge files that froze my PC.
I also try FLATTEN but did not see how it work , the ellipse stay an ellipse.

View 4 Replies View RelatedAutoCAD Visual LISP / AutoLISP :: 3D Polyline To Polyline To Spline With Max
Sep 21, 2013Due 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 Visual LISP / AutoLISP :: Labeling Polyline Areas
May 4, 2011Code 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

Mar 6, 2003I have a drawing which contains about 100 "areas". These areas are closed polylines. I would like to get a total area of all these polylines.
I have tried using AutoCAD 2002's AREA command, but I am only able to select one item at a time, (AREA, Add, Object). This is fine for calculating a few areas. It gives me a running total of each item that I select.
Using the LIST command works OK for a few items, but you still have to wade through all the other information to get the area info for each item.
Is there a way to select crossing ALL the areas that I have, and have it return a total?
