Doing a complicated shape out of line's and arc's in 3D. Then tried to turn them into a polyline some parts joined and some didn't. I can't see a gap's were one line hasn't touch the other. All look on the same plane. What am I doing wrong? I'm using autoCAD 2012.
View 5 RepliesIs there a way, when you are drawing a polyline, to have the tooltip box show the cumulative length of the polyline, rather than the length of the current segment being drawn?
View 6 Replies View RelatedI would like to take all the vertices out of a multiple-vertices polyline so that it reduces to just its start and end points, can this be done?
View 4 Replies View RelatedDue 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.
I've been working on a custom polyline object, and I've got it functioning!!Having said that, I plan to run its creation around picking a point for bounary selection.
(Other than trying to step through every vertecies) is there a technique I can thow the polyline data from a traceboundary result into my custom object? I've been trying to add the polyline from traceboundary to my object BEFORE it's added to the transaction by the way...I assume that's right, since I want to put it's data in my custom object then add my custom object to the transaction instead.

View 5 Replies View RelatedIs there any way at all to draw a new polyline - from the endpoint of another polyline, and have it automatically join as one polyline from the existing section??
I know this can be done via PEDIT, but its so laborious and soo many clicks, and I have alot of segmented Polylines that I need to consolidate when I draft.
Any way I can align a new polyline to a reference polyline (orig polyline).
The 2 polys will be generally the same length, however, the number of vertices will differ.
Also I need to mantain the same distance between the vertices on the new poly and the new and reference poly won't follow the same direction.

View 9 Replies View RelatedI can do this in AutoCAD Map but I have my doubts. I will explain in ESRI GIS terms (this is what I am familiar with) and I hope you can tell me if I can do this in AutoCAD Map. In ESRI ArcMap I can select a line and I can hit a Select by Location button. In this window I can select all of the objects that intersect my selected line. Then I can delete them or export them etc.
In AutoCAD Map I have a polyline selected. It is my road centerline. I want to be able to select all of the other polylines that intersect my selected polyline. Is there a way to do this? I need to erase those polylines. Usually I will pan to each of them and select them individually. It just seems to take a lot of time. My AutoCAD co-worker said I could use a fence and draw the fence through my polylines. It seemed to work ok but I accidently deleted extra things that I needed. So I'm back to manually selecting each one by one unless you know a different way.

The points are not lined up with any standard axes, but do have a common plane. I would like to create a polyline using the points above. I have tryed playing with 'polyline3d' and 'transformBy' but could not get it to work.
The 3d poly would be in an xref, and for my purposes i don't need it to be a 3d poly. Can this type of object be cloned? Or would it be better to collect the vertex points and create a 2d poly on top of it?

View 3 Replies View RelatedThe land measure company just sended me a file of a field they marked on the site. As you can see in the picture below the yellow polyline contains many grips. Because of all the grips my whole drawing is very slow and when i want to hatch the polyline and trim in it it takes minutes to load. My question is how can i change the polyline so i can easily hatch and trim it without waiting that long. Im using autocad 2014 and still learning it.
View 9 Replies View RelatedI am trying to get the distance of multiple block insertions that fall along a polyline to the startpoint/endpoint of said polyline.I can do this pretty easily using straight line (as the crow flies) distances between the block insertion and the polyline startpoint/endpoint, but I need the code to actually follow the polyline whenever it changes angle.
Is this possible using .NET? How to start it?Below is my code to to get the straight line distance between the polyline startpoint and block insertion point:
Dim dist As Double = Math.Sqrt((acPline.StartPoint.X - acBref.Position.X) * (acPline.StartPoint.X - acBref.Position.X) + (acPline.StartPoint.Y - acBref.Position.Y) * (acPline.StartPoint.Y - acBref.Position.Y))

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 created a series of splined lines into a polyline (pedit) which I want to extrude. When I extrude the polyline I only get an extruded polyline and not a surface. I need to create a mesh or make the surface a face to extrude to make a solid. I have not used AutoCad for some years and have forgotten how to do this. I know that I am making an incorrect procedure here somehow.
