AutoCad :: Extract Coordinates Along Polyline
Jan 3, 2008Imagine i have a polyline(2d or 3d doesn't really matter),and i want to extract the coordinates info of every vertex on the polyline from start to end.
How do i do that in AutoCAD?And if not is there a way to do it on any of the verticals?
AutoCad :: Getting Coordinates Of Polyline With Constant X Step
Aug 27, 2013in order to obtain a seabed profile for a school project, I need to get the Y coordinate of a polyline on several Kilometers with a fxed X step of 2m between each point.
For the moment, the only manual solution I have found is to create a vertical line every 2m and to get the distance between the intersection of this line with my polyline and an horizontal line representing the mean sea level.
Is there any way to automatize it because it is very long to do manually and I don't have enough time ?
I did not succeed in doing this with dataExtraction. I also found on the internet a LISP file which extract the coordinates of points contained in the window. Nevertheless, I was told it is not possible to create automatically points on a curved polyline with a fixed x step.
What I need at the end is an excel file of this type to use it in another software:
X(m) Water Depth (m)
0 15.121
2 15.134
4 15.147

AutoCAD .NET :: Getting Coordinates Of Intervals For Polyline Divided With Preset Length
Jun 10, 2013I have a an angular polyline (not horizontal or vertical). I want to equally divide the polyline with a specified length and get all separation co-ordinates at each interval. The line remains as polyline, I need to get only the co-ordinates of all the possible divisions for a given length.
I need a C#.Net function for this.
AutoCAD Visual LISP / AutoLISP :: Polyline Z Values Not Being Returned By Vla-get-coordinates
Sep 8, 2011I have a 2 point LWPOLYLINE that has the following coordinates at its end point when I 'ID' the point.
Command: id
Specify point: end
of X = 709369.3214 Y = 7153039.9690 Z = 269.2143
However if I use..
(vlax-safearray->list (vlax-variant-value (vla-get-coordinates (vlax-ename->vla-object (car (entsel))))))
I get this
(-450567.0 269.288 -450570.0 269.214)
and if I 'dump' the object..
; Coordinates = (-450567.0 269.288 -450570.0 269.214)
; Document (RO) = #<VLA-OBJECT IAcadDocument 09855674>
; Elevation = 7.17399e+006
I don't have a clue where the '-450567.0' is coming from.
I'm in Model Space in 'World' UCS, and I'm confused.. why does the 'ID'd' value not reflect whats going on when I use the vla-get-coordinates approach.
There are many other LWPolylines within the same model that behave normally.
I've attached the drawing (I think!)

Oct 22, 2013My drawing settings is set for US Feet. My Data Collector is set for US Feet. I only import a txt file into the drawing. My txt file coordinates match my Data Collector but never in the drawing. We're only talking about hundredth but I don't understand why it changes in the first place.
Example
Point 1 in txt file & DC --- 10000N 5000E
but in drawing --- 9999.98N 4999.99E

AutoCad :: Change Position Of Page 3 To Coordinates Of Choosing
Jul 28, 2011I have generated a batch of several thousand drawings, and then realized that my 'Page 3' paper space is positioned over page 2 in the model! Is there a way that I can tell 'Page 3' to change position to co-ordinates of my choosing, using only script, so that I can write a batch program to change them all?
My only other option is to correct the error in the master drawing and generate all the thousands of drawings again, which is why I'm keen to explore alternatives!

AutoCad 2D :: How To Change Elevation Of Each Vertex On Polyline
Sep 1, 2011how to change the elevation of each vertex on a polyline so that each vertex has a different value. The way I attempted this in the past was to click on polyline, click properties and give each vertex the required elevation. However when I looked back at the values I noticed that every vertex had the same value as the last elevation value entered. is it something to do with ensuring polyline is 3D?

View 2 Replies View RelatedAutoCAD Civil 3D :: Points Creation / Change Default Local Coordinates Permanently?
Sep 27, 2012I often create points manually. You get that dialogue box where you choose the layer and the default local coordinates, etc etc.
The local coordinates setting always defaults to Northing/Easting. (ditto the grid coordinates).
I set it to Easting/Northing as is standard around these parts and do my points, but if I close the box, when I reopen it to add more points later, it is back to Northing/Easting.
I cannot find a variable to control this behaviour.
I never need points to have north first and would like it to default to Easting/Northing at all times. Yes I'm using the Metric template.
Is there a way to change this default?

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 .NET :: Getting Polyline Data Into A Custom Derived Object (from Polyline)
Nov 11, 2013I'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.
