AutoCAD 2010 :: Sweep Around A Path
Jun 7, 2013
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.

I'm trying to do a 3d curve stair rail. I had the 3d spline path, I had the polyline rail profile, but after I sweep the profile, it end up being twisted at the end of the rail. Same problem happens when I did a sweep using a helix path, imagine a vertically placed rectangular profile at one end of the path then after using sweep command, the other end was somehow twisted on a certain degree. How can I avoid this twisting problem
See the before and after image. I wanted the rectangle profile to remain vertical throughout the whole sweep

Is there a way to sweep a 3d polyline in AutoCAD 2012? Colleague has a sweep path that he wants to put radii in the corners. I know that in the past you could not do it. I didn't see anything in any post that told me otherwise.

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 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.

Is there some way to get the overall length of a sweep path?
We are creating a 3D sketch to run a pipe cross section along and for the final material we need to know what the LF is.

I am using Inventor 2012. I am trying to sweep the pink shape around the pink rectangle but I get a weird result. Can I not sweep around a rectangle from the center? See attachment. I want to add more to the shape but when I do the result gets weirder.

I have a project I'm working on which requires a sweep path to be a graphical parametric mathematical function in x, y and z.
ex:
x=1.25*sin(10*t)
y=sin(t)*(12+1.25*cos(10*t))+12
z=cos(t)*(12+1.25*cos(10*t))
(this curve is a groove in the surface a bicycle tire. It spirals around several times and gets subtracted from a solid torus)
I was using an old version of NX I-DEAS and this task was easily accomplished with the "function spline" feature. Is anything like this possible in Inventor? I know I could create a list of points in excel, but I'd really prefer not to.

I am trying to recreate and 3D model the impeller of a heartmate II LVAD (URL....) but I am having problems with the sweep along the helical path. The profile is the vertical line and the path is the helix. I want to use a surface output for now. I had to use Solidworks to generate a variable pitch helix and import into Inventor.

I encountered problem when using sweep (path&guide surface)
It was enable to give you preview option (which is a surface that i wanted) but when i hit OK. It gives error as the text box.I tried again to no avail.

I have a sweep that follows the shape of the path sketch, but the sweep itself is made to the right of the sketch. How can I get it to fall directly on the path? I have attached a picture of the sweep as well.

I have been trying to convert this surface (attached file) into a closed volume. But somehow it isnt working.Then I tried to create this figure myself by creating two circles (one at the top and the other at the bottom) and then creating the path for using the sweep command , but it gives a error " sweep produces self intersecting curves".
convert this surface in to a sloid volume or if thats not possible can this geometry be created to the nearest possible approximation.

I am having a difficult time centered the helical path (the equation curve) and lofting the two profiles (centered) through the helical path in the axial rotation direction..

When preparing an assembly for export to a Revit family, all features need to be recognized as Revit features. I have a part which consists of a sweep with a 3D path, 2 planar sketches projected to a 3D surface to be precise. To make matters worse, it's a sweep whose end meets it's own beginning (the intent of this specific model is to just satisfy a shape, not necessarily reflect the way it's going to be produced). To date I have not found a way to have this sweep feature recognized as a Revit feature, be it as a single feature or multiple. I am running Inventor Professional 2014 on Windows 8 64-bit.

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've been following the Convert 2D to 3D video that is given in the Help section of AutoCAD 2012, and whenever I try to sweep the handle using the same methods that were used in the video it says that it is unable to sweep 1 selected object (when I select the path). I've attached the DWG file.
Also, when I went to use the 3D align feature I did exactly as the video did, but my handle wouldn't align with the side of the mug. It kept lining up with the side but never between the top and bottom of the mug like you'd expect. I kept having to move it to get it down where it needed to be.

I try to sweep along spline that made of elliptical arc and line.
Funny thing that I was able to create a solid few days ago by doing this method. Now I can't!
I tried even reload Autocad.

I have many drawings that were created with the xref's as full path and I need them to be relative path. I would just go in and reatch them as relative path but the drawings are complete and there are different layers frozen in each one.

I have found a way to convert FULL to RELATIVE using XRP2004.lsp but not the other way round. Main reason I want to do this is to change the Relative to Full, move the drawing and then revert them back to Relative.

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.

I am using autocad 2011. I am trying to attach a drawing as a xreg with a relative path. It keeps giving me relative path can not be assigned. I have tried saving the dwg. I have even started a new drawing and tried again but it keeps giving me the same error. All my drawing are in the same folder on a network drive. Another employee can open the drawing file from his computer and attach the same file fine. when He does it I can see the relative path. Is there a setting that I am missing?

My computer is not searching for the xrefs correctly. Whenever I switch to another job and try to load an xref, the computer searches under the last job I worked on and nothing else. I have several folders listed as search paths but it just seems to be ignoring them. We never used to have this problem and I cannot figure out what has changed.

When attach image (tif) with no path. is saved, de image will be saved without a path. dir. Only when we change the image (with RasterCAD) when we now save the drawing the hole path dir. will be saved.
When we used AutoCAD 2006 this will not be the case. The tiff. will stay no path. We move/copy drawing with image to other dir. very often.
-Originel
... dwg/tif
-To-Built
... dwg/tif
-As-Built
.... dwg/tif
Problem is that the image will be saved in the wrong dir.
