AutoCAD VB :: How To Split A Polyline At Its Self Intersection Points

Jul 21, 2011

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.

AutoCAD Civil 3D :: Extract Polyline Where Two Surfaces Intersect Each Other?

Jul 8, 2008

is there a way to extract a 3D poly line where two surfaces intersect each other.

i have ground surface and i have dam surface. they would like to show the filler material in the cross section graph.. so i copied then raised the surface the required depth.

so now the surface and side slope of the dam intersect. and i would like to trim the filler material surface to be in line with the dam.

AutoCAD .NET :: Extract X / Y Coordinates Of Points In Selection Set

Dec 20, 2011

I am busy writing a small app to find a best fit circle through a series of points that roughly follow the profile of an arc. This data was scanned in using a Farro arm and imported to AutoCAD.

I would like to use VB.Express and the AutoCAD API. So far I have managed to write some code (loosely based on some examples from the AutoCAD .NET Developer's Guide) to allow the user to select the points to process.

I have three questions around this issue:

a.) How can I set up a selection filter to limited the user's input to 2d points only?
b.) Once I have the selection set of points, how can I extract the "X" and "Y" values of each of the points to be able to process further?
c.) Is there some sort of Object model diagram for the AutoCAD API that I can download, or any (downloadable) literature to get started with the API and VB.Express. I have looked online for some books and Amazon list them, but a. they are in hardcopy format and b.) the most recommended one (i.e. VB.NET Programming for AutoCAD Customization - Level 1 Jeremy Winters) is out of print. I am specifically looking for downloadable books because of the delivery times and shipping costs to get a hard copy.

Illustrator :: Join 3 Anchor Points For Intersection Effect?

Sep 16, 2013

I'm seriously stuck trying to join 3 open paths with stroke only, into something of an intersection that is dividing 3 pie slots. However I can't join more than 2 of them, as the screenshot below the third one gets left behind, Join command doesn't work   Because I have the opacity down to 70% you can see the ugly overlap in the intersection and I need to join all the 3 points for them to look as they should. If/how this can be done in Illustrator?

AutoCAD .NET :: Creating A Polyline Using Distances Between Points?

Sep 25, 2012

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)

AutoCad :: Delete Points On 3D Polyline Vertices

Jul 18, 2011

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.

This is something I should know as a long time CAD user. I have line of points, ~200 on the screen and I want to draw a polyline through them without selecting each point. I know there was a command to select the first point and the last and ACAD would draw the line between. I am using AutoCAD 2010.

AutoCAD Civil 3D :: How To Create New Vertex Points In Line And 3D Polyline

Nov 24, 2013

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.

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.

AutoCAD Visual LISP / AutoLISP :: Distance Between Two Points Along The Path Of Polyline

Sep 10, 2012

There are times that I have a really long curb polyline that has both line and arc segments.  I wish to pick two points along that polyline and have it give me the distance between those two points along the path of the polyline.

Do we have this ability natively?  Have I been missing something all this time?  Normally I have to make a copy of the original entity, ... break, break, list erase or undo....

AutoCad :: Drag-select Multiple Vertex Points Form Polyline

May 13, 2011

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.

AutoCAD Civil 3D :: Create Intersection Design Using Intersection Tools

Mar 6, 2013

I am trying to create an intersection design using the Intersection Tools in C3D 2012.  I followed the steps in the tutorials, created a corridor on the major road, splitted the regions, created the intersection and added it to the major road corridor, and connect the regions with the intersection portion. 

I used the same assembly throughout the design just for simplicity, however, i notice that there are gaps of curb between the curb return section and the through section (as outline in red rectangles).

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.
