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?
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.
Any way to detect of there are objects currently selected using Autolisp, visual lisp or even VBA. I would like to be able to do something using that as a conditional, so that (assuming the hypothetical variable isSelected is an on/off indicator of whether or not something is selected) I can code something like this:
(if (isSelected) (...))
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.

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?

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.
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.

look at 0:33: [URL] ....
On my other pc camera locked on my vertex selectioned when I turn around them also
It's max 2012 on windows 7
Whenever I try to select a Curve to select 'Control Vertex' I get the options for the Camera instead, the only work around I have is to Hide the Camera which also switches off the image planes, then select the curve and select 'Control Vertex, and then re-enable the image planes.

View 2 Replies View RelatedI'm having a problem with Maya's vertex/point snapping function. This is a simple thing to do normally but in the 2014 student version (which is full functionality other than having a prompt saying it is a student version upon saving the file), it isn't working.
Basically the process is making a selection of vertices and with the transform tool active, MMB dragging the manipulator to snap the selection to a destination vertex. The pivot point/manipulator of the selection is moving and snapping to the destination vertex on it's own when I hold 'V' and MMB drag, rather than the whole selection moving with the transform manipulator and snapping to the destination vertex. This problem is also happening with the modelling toolkit which is really annoying. I have checked that i'm not in edit pivot mode etc.
The point snapping is working however for objects, but not in component mode as above.

View 1 Replies View RelatedI tried to set Polyline.StartPoint to new position (Point3d):

Also, I tried to do it as:

seg0.Set(newPoint3d(0, 0, 0), seg0.EndPoint);
It doesn't work also. I can do it as:

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.
I used the measure command to place points along a polyline. I'd like to draw a poly from the points that were created. I can't seem to snap to those points. I don't see anywhere to get the osnaps to snap.

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..

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?
