AutoCad 2D :: Reduce Number Of Vertex Points In Polyline Or 3DPolyline?
Oct 9, 2013
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.
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);
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.

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.
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.
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.
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.
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?
I've heard that you can reduce file size using polyline instead of line while drawing (or vice versa... don't remember) is it true and what exactly should be used. I think, why we would need the line tool at all if polyline more convenient.
I'm working on an illustration, and I would like to reduce the number of layers I have to work with, and I'm wondering if there is a way to "flatten" two or more layers together without flattening all of them. is there a pluggin out there that would let me do that?
Is there a way to reduce the number of subdivisions? Without clicking can't you just step "back" or select an area and reduce just the subdivisions in the selected area. I think I've tried everything, found something in a Maya document about reducing the hierarchy, which looked slick. The attached image should show what I mean (too many clicks on the button).
I want to reduce the number of pixels in a photo so I can send it as an avatar to another forum. How do I do this? Older version was easy but I can't find method in present update.
I’m importing an Autocad/AutocadLT 2007 dwg file into Visio 2010 to create a floor plan. I want to link each space in the Visio floor plan to an Excel spreadsheet. Each space will need to have an identifier – e.g. room number – in its properties in Visio and in its corresponding record on the spreadsheet. I’m dealing with a lot of rooms, so I’d rather not have to number them manually.
All of the rooms on the floor plan in the dwg file are polylined and all of the polylines are on the same layer of the dwg file. This layer contains nothing but the polylines. I also have another layer that has room numbers for each polylined room. The only thing on this layer are the room numbers as mtext objects.
As far as I can tell, the mtext objects aren’t linked to their respective polylines. After I insert the dwg into a new Visio document, using Insert>CAD Drawing, I right click on the drawing and choose CAD Drawing Object>Convert. In the dialogue box that opens, I check the box for the polyline and room number layers. I then select the polyline layer and go to Plan>Assign Category and choose “space”, which converts all of the polylines to spaces.
Is there a way to associate a room number with each polyline in AutoCad? Is there any way to map the room numbers on the room number layer in the Visio file to the Space ID property of the spaces I created?
I tried creating a block in AutoCad, on the polyline layer, consisting of a single polyline and a block attribute that stored the room number as a value. When I selected the polyline layer in Visio and went to Plan>Assign Category and chose “space”, to converts all of the polylines to spaces, the block was not converted to a space. It became an object in Visio that had its room number stored as a value, but it wasn’t a space.
Can I store the room number in AutoCad as xdata associated with each polyline and somehow have Visio recognize it as a property of each space?
Is there any way to create a custom property for polylines in AutoCad that the room number can be stored in?
I'm trying to use adobe illustrator to color the background of a photograph green while keeping the person in the picture the same color.
I used live trace to get a vector image and then attemped to use live pain to finish the job, but I end up with thousands of blue lines and gaps that are too small to color in. Is there anyway i can reduce the number of gaps so that i can actually paint the background?
I've already tried the gap options and adjusting the settings to small medium or large did nothing.If this isn't possible, is there any other feature in adobe illustrator that would allow me to achieve my goal?
I have a photograph with a person in the middle; i want the person to remain the same and the background to be changed to green.
I'm currently trying to use the draw > point > measure tool to create a set of points around a polyline but I can't seem to get them to start at a point that I want. When I try and create the points they start from a random place.
I am aware of creating a polyline and using .AddVertexAt() to give the points, my question is if I want to create a polyline in acad I generally will pick a point and then type out @10.5<0 or something similar of that nature to pick my next point. Is it possible to add vertices to a polyline in .Net giving it the distance and angle of one point2d to the next point2d?
Example:
acPoly.AddVertexAt(0, New Point2d(0,0),0,0,0)
acPoly.AddvertexAt(0, New Point2d(1,0),0,0,0)
but instead?
acPoly.AddVertexAt(0, New Point2d(0,0),0,0,0)
acPoly.AddVertex ( use code equivalent of New Point2d = @10.5<0 from point at 0 index)
I'm trying to split a polyline that have some intersection points at its intersection points. So, if a polyline have two self intersection point, then it will become three different polyline. I attached an example of a polyline that I want to split.

I 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.
