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 RelatedI have used PEDIT to join multiple polylines, which now appear as polylines. But when I use QSELECT to show all open (non-closed) section, one polyline still shows up as open.
I've attached the file I'm working on. The polyline in question is the green outline on the object on the right.
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.

Delete some vertex in this polyline.

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.
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.
how 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 RelatedI 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?
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.

Is there a methoed or trick to realize a polyline is closed or not?
View 3 Replies View RelatedHow 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 closed polyline:

Is there a command or lisp that will allow you to select a closed polyline and trim everything outside of it even if the items are blocks that aren’t exploded?
I’ve tried EXTRIM but that fails on blocks.
When I try to extrude this closed polyline (yes it is closed) I get the message "Cannot sweep or extrude a self-intersecting curve." I do this sort of extrusion all the time (closed polylines with various geometry) and usually have no trouble.
View 9 Replies View RelatedI've been using the admittedly pieced together code in order to insert border blocks around a closed polyline. Yhe problem I'm having is that when the Block angle is say "zero" the block is inserted the same way both on top and below the polyline. Since the blocks surround the polyline the blocks on the downside should have an additional 180 degree rotation. How to deduct that the portion of the polyline is in a certain quadrant and adjust the insertion angle as necc? I 'm not sure thats even the best approach.
Dim pso As PromptStringOptions = New PromptStringOptions("Enter name of block to create reference: ")
Dim pr As PromptResult = myEd.GetString(pso)

Is there a way to select objects within a closed polyline? I thought there was but I can't remember how to do it.
View 2 Replies View RelatedPresently the "AREA" of a closed polyline is in "sq-in" first, THEN "sq ft".
For everything I do, and likely others, I need sq ft - without having to waste time and roll my cursor over the results.
Is there ANY way to change this default to have sq ft FIRST!??
I was wondering if there is a settings for the displayed values in a polyline's properties. Such as area. Normally it will display square feet but I would like for it to also display acres. I know it a simple conversion, but over the course of a year or more it could save me alot of time.

View 2 Replies View RelatedI am trying to find a command that will hatch the inner edge of a complex closed poly line, rather than hatch the entire area inside the poly line.
When I have simple shapes such as a rectangle I create a smaller rectangle inside the first that is 1' (or whatever I want my hatched area to be) smaller on all sides than the first rectangle. I hatch by selecting the two rectangles; I change the "Associative" hatch property to "No" and then delete the inner rectangle.
My problem now is that I have a complex closed poly line that I would like to hatch the inner perimeter with a set thickness, say 1 foot. Is there an easy way to hatch a inner boundary of a closed poly line or to recreate a scaled down copy of the poly line that is a set distance smaller all around. I hope I have conveyed the question clearly enough.
I can draw a closed polyline representing a closed area.
I can then toggle its 'closed' property and it seems to make no difference. area is same, I can extrude or create regions, I can hatch in either case.
in which specific situations we should bother about whether a polyline is closed or not?
I currently click on a shape to see the grips. Then I put the cursor on a grip and see a window open that gives me the options of Stretching a vertex, Adding a vertex, or Removing a vertex. Is there a way when adding a vertex that you can add Mulitple vertexs without having to click on add vertex every time.

I'm trying to calculate the principal moments (and section modulus) of a slection of closed polylines.
On this blog, I read that there are some new classes and functions in the AutoCad 2014 objectARX that can do this.
The one that interests me the most is 'RegionAreaProperties.PrincipalMoments Property'.
However with my limited programming skills, I can't get it to work in vb.net.
I thought is was just a property of a region, but something like 'myregion.RegionAreaProperties.PrincipalMoments' does not work.
With the code I already have I use a selectionfilter to select multiple closed polylines. I can convert these to regions if nescesary. But what is the next step? I can't find any samples of it. Not even in the Autodesk Developer's Guide.
I have linked my drawing to a database with text inside a closed polyline. Is there a way to have the area of the closed polyline stored in the database as a live area.
View 8 Replies View RelatedI drew a very complicated 2-D plot this afternoon. The most majority of the plot is composed of different straight lines, arcs. Then I used the polyline function to join them together to form a closed single polyline (Modify->object->polyline).
Later on I want to change something in part of the polyline. Then I used the 'pedit' again, I chose 'open'. But the whole polyline won't break into its original segments. I tried through all the menus, just cannot find the right tool for this purpose.
Does it mean I have to start over from scratch to redraw the whole plot?
I am a landscape architect, and am trying to use bushy linetypes to delineate blobs of mass plantings. I created my custom line types, and tweaked them to the point where they look the way i want, but whenever i have a curve the line type faces in not outside the closed polyline. all of my shapes are closed poly lines, and i need the linetype to face out other wise it looks weird. I am attaching a picture the strait line to the right is the way that it is supposed to look, but in the circle you can see how the points are all facing in to the middle of the circle? reversing the direction dose nothing, and using a or u in the place of r in the linetype shape code doesn't work either below is the line types code and image.
