I find it absurd that AutoCad C3D doesn't have a vehicle sweep routine built in to the design software. This is as basic to roadway design as super elevation is to horizontal curvature.
Buying third party software such as AutoTurn or Pathplanner R4 seems ridiculous.
I am attempting to model an internal 1/8"-27 NPT thread, both the through hole and the tapered part of the hole are modeled, but after I draw the helix and the polygon and orient the polygon to the helix correctly, (or even if I don't, I have tried it) it keeps saying unable to sweep object. I am using Sweep with Alignment with the No option. If I select the polygon first, then click sweep, it works, but rotates the polygon so that what I get ends up looking nothing like a thread profile.
I have tried reducing the polygon radius down to a ridiculously small value, thinking it might have been interference due to a possible trig miscalculation, but with no success, still have the same issue. FYI, I am using a .037" turn height for 27 TPI and a polygon radius of .0214", with a helix small end radius of .177" and large end radius of .189".
I'm using AutoCAD Civil 3D to model inner city utility construction projects. For my research project, I need to include water and storm pipes, but also various sorts of cables. Currently, I'm manually creating cables profiles using plines from existing 2D drawings and the sweep function.. a very cumbersome taks.
I was wondering whether there is a way to speed this process up. At the moment, I draw a circle, copy it myriads of times, and sweep each along the dozens of plines (one by one). I cannot select multiple lines and sweep them all, can I?
whether I can select mutiple plines to sweep all at once?
Solution to getting a horizontal sweep to miter with a vertical sweep? Or maybe there is a way to pick a path? A feature in the full version that Autodesk deemed unnecessary for LT.

We recently updated our servers and with that the path to all of our drawings. For example what was once located at W:FilesAutoCAD is now located at W:CorporateAutoCADDrawings. The problem is every time we open an old drawing for the first time we must redirect all of the xrefs to the new location. My question is, is there any way to do this automatically for all drawings when they are opened? Is there a way to tell the software to replace "FilesAutoCAD " with "CorporateAutoCADDrawings"? I'm sure others have encountered this dilemma.
I used autocad 2010 at my old job but I now use 2012. Now, I keep getting a "bad definition for linetype" error when I try to use linetypes that worked fine at my old job. Someone suggested that I reestablish my support paths but I don't know how to do this.
I want to join two paths to create a shape that I can fill but at the same time retain one of the original paths (the red one in the image below). I can copy the path I want to retain but surely there is a more elegant solution. See below for for an illustration:
On solidworks, There is an option to rotate the profile along the path as it sweeps. I'm curious if there is anything similar to that ability in Inventor? And if not, if there is a way to create a helix along a curved axis.
I have looked through these forums and found plenty of sweep problems and the answers to the problems but none for this particular type. I made a 3d intersection curve and am trying to sweep a profile along that curve but I keep getting the discontinuous segments error. I am using standard inventor 2011.
I have a tunnel profile that I need to sweep around a path. This path is a 3D Polyline but it has arcs and slope associated with it. The sweep command has this automatic banking or twisting to it that just screws everything up. The profile needs to stay perpendicular to the path and the floor of this tunnel needs to remain flat.
I have attached the actual working drawing. It has the profile (which is a simple typical tunnel) and the path all situated.I'm working in AutoCAD 2012 if that really matters.
Trying to create a 3D sweep. I want to keep the sweep parallel to the XZ plane (like a parting surface). In the attached part, there is a SweepSrf3 that has sort of what I am trying to do, but it does not go all the way around the path. Notice how the sweep is parallel to the plane. I tried to do the same thing in SweepSrf4, by selecting the 3D Sketch1 as the path, Sketch2 as the profile, and Workplane2 as the Guide Surface. That failed.
In SweepSrf4, the only way that I could get the sweep to come close to working was to use the 3D Sketch1 as the guide rail and the circle as the Path. Seems like I need to use the circle as the guide rail and the 3D Sketch1 as the path to get what I want... but that fails.
I'm trying to sweep it around shape like this But it won't, it says "The selected path curve is not valid." - so what do I do? (it is polyline) Is there maybe some other way to get this 3D shape fast?
Is it possible to sweep a solid along a 3d sketched line path to cut a groove / slot? This is like milling a slot in material on a milling machine so the cutter goes along a path removing material.
I can draw a rectangle that represents the side plane of a slot type cutter and this works but in the corners it is not working like a round cutter and leaves sharp corners which then need filleting to finish, but also I am not sure if it is cutting exactly as if a solid round/cylinder cutter would.
I am having difficulty aligning the profile for a sweep feature. I need the profile to be normal to the path, but aligned vertically. In other words, the rectangular profile should remain "plumb" along the entire sweep. Is there a simple way to do this?
I have shared the sample files, trying to use the profile in two different ways, through Dropbox (they are too large to upload). I am using Inventor 2013.
I am trying to sweep a profile throughout the helical sweep path which is a series of 3d sketches. The sweet prifile sweeps correctly to the first 3d sketch profile but whin I select the second line the preview is gone and Inventor gives me an error saying the sweep cannot be done. how I can have the sweep done throughout the helical structure.Attached is the ipt file.
am using Inventor 2012. Is there any way to select two rails when sweeping? One for the x and one for the y. I can only select one rail. If I choose Profile Scaling X & Y, it does not sweep the way I want to.
I have created a pipe using sweep through 2 planes and 3d sketch. I want a specific bend on that pipe to be extracted for drawing purpose. How do I do that ?
So I have a 3D sketch. As you can see in the image attached, there are circles on a 2D plane that are attached to circles on another 2D plane via all the purple lines. My goal is to do a sweep for each of the circles so that I can get a bunch of holes. However, after I do the first sweep, the sketch disappears (see pic 2) and I do not know how to go back to the sketch so I can sweep again and again.
We are developing an equation driven 3d spline using VBA.
It generates a 3D spline, guide rail, and tool profile, but we're having trouble figuring out how to do the actual "sweep with guide rail" using the API.
Attached is an .ipt of the shapes our program is generating automatically. The problem is we are having to manually create the sweep after the geometry is created.
How can we automate the sweep with guide rail process?
Any way to sweep a rectangle along a 3D spline and keep the top of the rectangle parallel to the ground?
I make complex spiral handrail and when i sweep and rectangle along a 3D spline normally, it twists and is wrong. I know that there is a plug-in on sketch that is specifically designed for this called 'Follow me and keep' .
I want to sweep the "cutting tool" through the helix to create a inner thread of my nut. When i set "Align" to "NO" it refuses to sweep. If i set "Align" to "Yes" it works perfectly but the result is of course totally wrong.
