AutoCad 3D :: 3D Polyline / Curve
Feb 27, 2012
The objective is doing (as in the photo, like the others in blue) a cement bar painted in blue with 2 cm that circles the window. The problem is that the 3D polyline (which i've already did it) is curve.
The other flats ones i did it with 2 polys, then region, then subtract, and a finely extrude. I've attached one photo.

I've been using AutoCAD for many years and finally gotten fed up with this:
If I have a polyline which has a curve in it, and I PEDIT and CLOSE it, AutoCAD automatically closes it with a curve. Does any setting which I can turn off, so that it's closed with a straight line instead??

Any unpublished system or drawing variable that allows you to toggle to the classic grips on a curve-fit polyline? I have searched online and checked with our reseller but we have been unable to find a way to switch to the historic grips that are available on a curve-fit polyline.

I have a sinusoidal curve, that I've created using a third party app, which has worked really well. But the app only produces the form in a straight line and i now need to fit it to a number of curves.
I have a form of 3 radii and a couple of flats, which the sinusoidal form needs to fit along. All this work is just in 2D as i need to output the dxf into a CNC machine.

I´m looking for opportunities to can modify a polyline with 4 or more segments in a polyline with arc. I think it´s possible to pick start and end segment first and than all straight segments to will be in arc segments.

Is 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?

I 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?

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.

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.

I want to draw hyperbola curve whose equation is x^2/a^2 - y^2/b^2=1. May I use equation curve tool to make the above hyperbola.
I have also made a hyperbola curve of aforesaid equation through conventional method on mathematical ground in the past.

I have ran an analysis and SSA gave me Error 607 on the report. It says "Inlet A9 gutter capture curve is not a valid curve."
A couple things I did different from the video lectures...
I selected user define for the Tc to figure out Q. i computed those manually.
For the Inlets I have selected Maximum Capture Cutoff.
There are some inlets in this model I created that do not capture 100% of the flow so i created conveyance links to account for the bypass flow.Not sure why is not recognizing the Curve?

Is 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.

Why in LR4 is the Tone Curve default set to Custom with a contrast lowering curve? I would like the default to be linear, but I can't remember how I set that up in LR3.

I 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.

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.

I have the following points that when connected create a polyline (Px = X,Y,Z)
P1 = 149.941738,99.586521,6999.370079
P2 = 146.5869,91.262907,6999.250781
P3 = 143.883334,82.716622,6999.701863
P4 = 142.39435,83.120478,6998.429138
P5 = 141.276439,98.451501,6993.00069
P6 = 130.73509,105.487377,6982.747181
P7 = 131.486628,107.340559,6982.777312
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?

I'm curious if there is a way to array objects which are a set distance off of a polyline, along the polyline at a set distance on center. For instance having a circle a 1/2" off of of the polyline, and arraying that circle at 12" on center along the polyline.

The 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.

I 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))
