Delete some vertex in this polyline.
hhh1.png
Example as: i have 3 vertex (0,1,2) and you can see vertex 1 stay between vertex 0 and 2. Now, i want to delete this vertex how can do that. Similarly, i want to delete some vertex 3,5,8.
problem I am encountering with adding vertices to the ends of polylines in AutoCAD LT 2012:
I typically use the drop down menu that shows up when hovering over the end (or mid) point of a polyline to choose "Add Vertex" to a polyline. If I do this to one end-grip of the polyline, it will add it onto the end of the polyline as an extension (desired and intended effect). If I do it to the other end-grip, it will add the vertex behind the end of the polyline as if I had used the mid-grip to do it (not the desired effect). If I wanted a vertex in the middle of two end points, I would do this procedure using the mid-grip, not the end-grip. One would think that by using an end-grip, it would come off the end, not go into the middle....one would think.
The Question: Is there a short key or quick command to use to guarantee the added vertex will extend from the end of the polyline rather than add one in the middle of the polyline, no matter which end I am trying to extend?
I have imported a dwg witch was created by Revit. The problem is that it creates polyline vertex for curves. But i want a arc, or at least not so many segments.
on the image; on the left is what i got, on the right is what i want.
I have a set of polylines that have easting, northing and height values. However, I want to display the co-ordinates of each vertex within the polyline.
When I scroll over the vertices of the polyline the values change (bottom left screen) I simply want them displayed as a text.
I have a method for inserting a vertex to a polyline. But this does not work for closed polylines for the case shown below. The code fails if the point is on the last edge of the polyline.
public void AddVertexOnPolyline(Point3d addPoint,Polyline editPolyline) { Document acDoc = Autodesk.AutoCAD.ApplicationServices.Core.Application.DocumentManager.MdiActiveDocu

Is there a simple way to add a vertex anywhere you want in a shape or polyline? I double click those items and a menu comes up and I can add a vertex but it limits me where I can add the vertex and then it is a pain to make it work like I want.
View 2 Replies View Relatedhow 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?

I want to create new vertex points in feature line and 3dpol.
I have this:
try
{
if (obj.GetType() == typeof(Autodesk.AutoCAD.DatabaseServices.Polyline3d)) {
Polyline3d p3d = (Polyline3d)trans.GetObject(entRes.ObjectId, OpenMode.ForWrite);
[Code]....
In this code line:
oFtrLn.InsertFeaturePoint(punt, AeccLandFeatureLinePointType.aeccLandFeatureLinePointPI);
always catches the same Exception "the value is not within the expected range" .I have translated it because I get "El valor no está dentro del intervalo esperado". Perhaps is this: " Value does not fall within the expected range.".
I have tried it with different point3d values but always catches Exception.
With pol3d I have similar problem.

Any way to reduce the number of vertex points in a polyline or 3d polyline and retain the basic shape but without having to redraw over the top it?
Ideally, I would like any adjacent segments which are in the same direction as each other to become one segment.
In my image you can see the number of points it has, the majority of which are not necessary for my needs (it was imported from a client's drawing). My desired linetype will also not show because of this.

How can I drag-select muliple vertex points form a polyline, a workaround I found is:
-select object
-shift select first vertex, shift select next vertex, etc
But this workaround is limited because I want to delete those vertexes, I cannot find the remove vertex command when I have multiple vertexes selected.
I have a program that makes 3d polylines from various data. That 3d pline then gets added to a civil 3d surface as a breakline. I want to modify the pline with my program, but preserve the handle, as I think that is what C3D uses to decide if its part of the surface. I tried this as a sample with no luck:
;DELETE 3RD VERTEXT FROM 3D PLINE
(DEFUN C:T3 ( / EN ENAME ENT ENTL)
;GET 3D PLINE
(SETQ ENT (ENTSEL "
Select 3D Pline:")

I know you can modify a vertex, but what about add and delete with entmake and entmod? I also considered using activex for this task, but you can only add verticies from what I could tell in the object browser of VBA, not delete them.
What I will be doing is deleting all the verticies and adding back the correct ones. Or if there was a way to transfer a handle to a new entity after deleting the old, that would suffice too.
I need a lisp that can remove all objects (lines, polylines, blocks etc.) outside of a polyline. polyline is closed and shape is variable, so not rectangle.
View 3 Replies View RelatedI have a couple of hundred 3D Polylines which have point crosses at each vertex. Any way to remove these point crosses that fall on the 3D Polylines.
(IF 3D point vertex = any 3d Polyline vertex THEN delete)
Reason I can't just filter out the points and delete is that there are points that don't fall on Polylines which I want to keep. All points are on the same layer. Polylines are on various layers. Data is from a 3D topographical survey.
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 2 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.

View 5 Replies View RelatedIs 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.
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.

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.

View 1 Replies View RelatedI know this is probably very simple and despite having been using CAD for 15 years I cant find the answer.
In every cad version Ive had, you can do the following:
-You draw a simple line, then you want the right vertex to move 500mm to the right, so you select the vertex, pull to the right with polar tracking, type 500, and job done. Same if say you wanted the same vertex to move up, down etc.
If i try this same thing with a line at an angle, it works as i would have thought, but if i do it with a horizontal line and want to move the vertex horizontally, it seems to act weird and draws the line 500 but from the left hand point.
I have a pdf xref with a polygonal clip applied. I'd like to change the shape of the clipping area and need to add vertexes to do so.
How can I add a vertex to a polygonal pdf clipping?
Usually I can just select a vertex and pressing crtl will cycle through add vertex, remove vertex, and if it's a line segment, change to an arc. When I select the vertex of a polygonal vp clip I can't do this.
