AutoCAD Civil 3D :: Draw Polyline From Point To Point Using Imported Points?

Aug 16, 2013

Im still new to Civil 3D and i would like to know how to connect inported points using 3D polylines. I imported my points from Excel in a PNEZD format. How do i get the 3d poly line to snap to my points so I can Connect them? someone mentioned using a feature line to connect the points but im not sure how or what that would do.

AutoCAD .NET :: How To Set Polyline Start Point

Aug 12, 2012

I tried to set Polyline.StartPoint to new position (Point3d):

Polyline.StartPoint = myNewPoint3d;

I have "not implemented" exception.

Also, I tried to do it as:

var seg0 = acEnt.GetLineSegmentAt(0);

seg0.Set(newPoint3d(0, 0, 0), seg0.EndPoint);

It doesn't work also. I can do it as:

acEnt.SetPointAt(0, my2dPoint);

But it's 2D point, not 3d

Of course I can remove polyline and create it again, but. How to set start point correctly for 3d point?

AutoCAD .NET :: How To Get A Point In Polyline With Set Distance

Oct 23, 2013

How to get a point in the polyline with a set distance and obeying my current ucs. A projection of the point as an orthogonal snap.

I wrote a code creating a polyline between the lowest and the highest initial polyline and obtaining the intersection. But when it comes to many points the rendering is quite time consuming.

AutoCad 2D :: Snap Polyline To A Point

Jan 21, 2014

AutoCAD .NET :: Create Polyline With Insertion Point Prompt

Mar 13, 2012

I've been going through some examples on [URL] to create polylines and i've managed to make some code run. One thing that I can't seem to find information on though, is how to use the default AutoCAD command line options in my code. For instance, I would like to be able to prompt the user whether they would like to snap the polyline to an insertion point, everytime they create a new verticie.

Below is some example code from the site that i'm working from:

namespace MyPlineApp
{
public class MyPlineCmds

AutoCAD .NET :: Detect If Selected Point Of Polyline Is Its Vertex?

Feb 10, 2012

I would like to know if there is any way to detect if selected point of the selected polyline is its vertex?

1. The user is drawing rectangle or any other figure with polyline.

2. Entering command "GetMe".

3. Selecting polyline.

4. Selecting point.

Is there any built-in function in Autodesk's API?

AutoCAD .NET :: How To Find The Start / End Point Of Polyline With Program

Jun 6, 2013

I draw 3 lines to form an open polyline. They are still in lines, not converted into a polyline.

How do I find the start or end point of the polyline with program? I  am thinking to check all points which is not shared by two lines.

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

Mar 19, 2013

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?

AutoCAD Visual LISP / AutoLISP :: Block Insertion Point Is Within A Closed Polyline

Oct 11, 2011

I've have code to test if the insertion point is within a closed polygon. But prior to testing the insertion point I use ssget to trim the selection set initially..

(ssget "CW" Pnt_List (list (cons 0 "INSERT")(cons 2 BlockName)))

this requires that the whole Crossing Polygon is visible, so I do a zoom first. This requires time. Is there a way I can do this that does not require the zoom?

AutoCad 2D :: Drawing Polyline To Have Tooltip Box Show Cumulative Length Of 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 .NET :: Getting Polyline Data Into A Custom Derived Object (from Polyline)

Nov 11, 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.

AutoCad :: Automatic Join Polyline Onto Existing Polyline?

Sep 16, 2011

Is there any way at all to draw a new polyline - from the endpoint of another polyline, and have it automatically join as one polyline from the existing section??

I know this can be done via PEDIT, but its so laborious and soo many clicks, and I have alot of segmented Polylines that I need to consolidate when I draft.

AutoCAD Civil 3D :: Align Polyline Onto Another Polyline

Mar 22, 2012

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.

AutoCAD Map 3D :: Select Polyline By Intersecting Polyline (select By Location)

Aug 10, 2012

I can do this in AutoCAD Map but I have my doubts. I will explain in ESRI GIS terms (this is what I am familiar with) and I hope you can tell me if I can do this in AutoCAD Map. In ESRI ArcMap I can select a line and I can hit a Select by Location button. In this window I can select all of the objects that intersect my selected line. Then I can delete them or export them etc.

In AutoCAD Map I have a polyline selected. It is my road centerline. I want to be able to select all of the other polylines that intersect my selected polyline. Is there a way to do this? I need to erase those polylines. Usually I will pan to each of them and select them individually. It just seems to take a lot of time.  My AutoCAD co-worker said I could use a fence and draw the fence through my polylines. It seemed to work ok but I accidently deleted extra things that I needed. So I'm back to manually selecting each one by one unless you know a different way.

AutoCAD Inventor :: Setting Up Point On Different Layer To Mark Center Point Of Circle?

Nov 15, 2012

I need to find a way how to insert a point or a * on the center point of a hole and put it on a different layer. The reason for this is - I am a CAD tech for a welding shop and we cut parts out of steel and we use the dxf file format for our plasma table to cut parts. For example : if i have a 1 inch thick plate and want to put a 3/4'' hole in the plate the hole will be distorted because the hole is smaller than the material thickness. For these situation we can use the plasma table to burn a point or a dot on the center point of the hole. But to do this the point or dot must be on a different layer in the dxf.
