I draw 3 lines to form an open polyline. They are still in lines, not converted into a polyline.
How do I find the start or end point of the polyline with program? I am thinking to check all points which is not shared by two lines.
I tried to set Polyline.StartPoint to new position (Point3d):
Polyline.StartPoint = myNewPoint3d;
I have "not implemented" exception.
Also, I tried to do it as:
var seg0 = acEnt.GetLineSegmentAt(0);
seg0.Set(newPoint3d(0, 0, 0), seg0.EndPoint);
It doesn't work also. I can do it as:
acEnt.SetPointAt(0, my2dPoint);
But it's 2D point, not 3d
Of course I can remove polyline and create it again, but. How to set start point correctly for 3d point?
Using Lisp or VLisp, how can I find the Start & End Point of an AEC_WALL ent. ?

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.
View 3 Replies View RelatedI'm trying to draw a plan of my house in Autocad 2009 but I seem to be endlessly using trim and extend because I can't easily select the points that I want with osnap. Eg. imagine I have a box, and I want to start drawing another box inside it that has each side as 10 units smaller than the corresponding side on the outer box.
Step 1 - I draw a small line from the top left corner of the big box using the endpoint snap, typing in "5" for the length.
Step 2 - I then do the same at right angles to the first line to get me to the starting point of the inner box. This always leaves me with 2 small lines to remember to delete.
Step 3 - Then in order to draw the top line of the inner box I end up drawing to a random length because I can't say "draw until 5 units away from the right hand side of the big box", then I end up trimming it later once I've repeated steps 1,2 and 3 for the next side of the inner box.
I know in my example above I could have scaled the box down or something but that's not what I'm getting at. I really want a way of selecting line start and end points that are a known position away from an existing point.
I am looking for something a lisp or program that would do a light point by point of fixtures in a plan.

i have a set of coordinates, not on the polyline. i want to find the polyline width where that coodinate intersects perpendicular to the polyline (shortest distance). without going through all the vertices.
i have a polyline with many segments with varying width, which are constant through the each segments (no taper width). need to read off the "instantaneous" width.

View 1 Replies View RelatedI'm using VB.NET to write a routine that autmatically calculates the area of the polyline nearest to a block (the pline surrounds the block) an then adds the area to the blocks attribute.
I managed to write the program to do this manually for a selected pline and block.
How can I automatically select a pline nearest to the selected blocks' insertion point?
I am trying to follow some directions and the call for a spline to be drawn onto an image. I can only find a polyline which doesnt work like I need it to. As I understand it a polyline will put a curved line as close as it can to a series of points, whereas a spline will "join the dots". I need to join the dots but with a curve not a jagged straight edge.

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.

One thing that I can't seem to find information on though, is how to use the default AutoCAD command line options in my code. For instance, I would like to be able to prompt the user whether they would like to snap the polyline to an insertion point, everytime they create a new verticie.
Below is some example code from the site that i'm working from:

View 2 Replies View RelatedI have a problem with absolute and relative coordinate regarding drawing an arc.
From my previous studies, I thought whenever I input coordinates in command line, in order to use absolute coordinates I just enter them. If I want to use relative coord, then I can prefix them with @ sign.
For an arc I input as follows: start point: 0,0 2nd point: 500,500 end point: 1000,0. I was expecting to get a half circle from origin to 1000,0 point but to my surprise I find out that CAD gets the input coordinates as relative.
Am I missing something? 1.dwg1.jpg Is this behavior same for all other object drawings?
