I am basically looking for a way to get the length of each polylie segment in the overall polyline. Not the total length.
I then need to comapre these lengths. I guess I could do some math to get the values of the verticies, but is there a built in method to do this? how to get started?
I want to draw triangle in segment of polyline in segment direction.
I have target segment and center point of it:
Polyline line = ...
LineSegment3d centerSegment = line.GetLineSegmentAt(centerSegmentIndex);
Point3d centerPosition = centerSegment.MidPoint;
I can find direction of this segment:
Vector3d zaDirection = line.GetLineSegmentAt(centerSegmentIndex).Direction;
Next, I create list of points:
List<Point3d> points = new List<Point3d>();
points.Add(centerPosition);
points.Add(centerPosition.Add(new Vector3d(ZASize, +ZASize, 0)));
points.Add(centerPosition.Add(new Vector3d(ZASize, -ZASize, 0)));
And draw it:
wd.Geometry.Polygon(new Point3dCollection(points.ToArray()));
Ok, I have triangle but... it's not in segment direction, it's X-direction.
I try to rotate it:
points.Add(centerPosition.Add(new Vector3d(ZASize, +ZASize, 0)).RotateBy(0, zaDirection, centerPosition));
But it's not the same as I want.
How I can draw triangle by serment direction?
Is it possible to determine the sum of the lengths of all of the polylines on a certain layer? I'm trying to determine the total length of joint sealant on a building's exterior.
View 8 Replies View RelatedI need to have a table that updates when I change the length of a polyline, These lines are split up into segments for different types of materials. We usually add this up manually but would like to find a solution that is a little more automated.
I have mostly a background in GIS and have excellent knowledge of Autocad Map. I came up with a solution by creating a shapefile and making a multi-part feature for the segments. I added a table and connected to the .dbf file of the shapefile. I then calculate out the lengths of the line and update the attribution of the shapefile. Easy and took a few minutes to do.
I just want to know if there is a better way of doing this. I have did some searching and have found some information about alignment tables.
The task should be similar to the _measure command but, I would like to divide the spline into lengths that I give in input. (Decided by user)
e.g. Length of spline: 10.000 meters
Place a block at length:
- 1238 m
- 2005 m
- 2018 m
- 2458 m
- 4098 m
and so on..
How I can do that? It would be perfect if it would be possible to give an excel file with the length values.

View 4 Replies View RelatedI 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?
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?

Is there a way, when you are drawing a polyline, to have the tooltip box show the cumulative length of the polyline, rather than the length of the current segment being drawn?

View 4 Replies View RelatedDue 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.
I've been working on a custom polyline object, and I've got it functioning!!Having said that, I plan to run its creation around picking a point for bounary selection.
(Other than trying to step through every vertecies) is there a technique I can thow the polyline data from a traceboundary result into my custom object? I've been trying to add the polyline from traceboundary to my object BEFORE it's added to the transaction by the way...I assume that's right, since I want to put it's data in my custom object then add my custom object to the transaction instead.
I want to convert a 3D polyline to 2D polyline.

How i'm adding lengths of individual plines...I am running MEP 2013 and lately we've been doing a lot of measuring of plines...The problem i'm having is that we are supposed to add 24' to every length...So if I measure a polyline and it's 10' long, the number i'm supposed to be putting on the drawing would be 34'...Is there a way to create a command that will automatically add what I need to every pline?

How can I make such a part so that i can insert it into an assembly multiple times but have different lengths? I'd rather not make multiple pieces of foam for every single assembly for all of our product lines and am looking for the "one foam to rule them all" option. I would assume this would be an ilogic component I would have to create, but i haven't really made a part like that yet.

How to arrange them so that I get an triangle. I could draw 3 lines and then start rotating them till I get satisfactory result but can this be done any quicker?
Any way I can align a new polyline to a reference polyline (orig polyline).
The 2 polys will be generally the same length, however, the number of vertices will differ.
Also I need to mantain the same distance between the vertices on the new poly and the new and reference poly won't follow the same direction.
