AutoCAD 2013 :: Creating Path For Using Sweep Command
Jul 11, 2013
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.

How does one draw a complex curved line to act as the path for a sweep in REVIT 14?
I need to create an arch (shown in elevation), that follows a curved path (shown in plan).

Is there a way to change the default setting for the Array path command?
When I use the arraypath command I:
1st - Select Object
2nd - Select path curve
3rd - Type in "I" for Item to change to my desire spacing.

I am using AutoCAD 2013. During the creation of 3D while I am using Presspull Command, it works fine in the beginning after some time, AutoCAD seems to be hang while I took the command but once I press Esc, AutoCAD continue working.

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.

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'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.

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.

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 need to SWEEP the yellow rectangle in this drawing along the magenta 3DPOLYLINE. This is a stair stringer for a winding stair I'm trying to model. The trouble is that when I SWEEP it the rectangle begins to rotate and ends up all out of whack once it gets to the top.
As I understand it, this is something that AutoCAD does not handle well and something like 3DsMax does. Problem is I don't have 3Ds Max and if I recall correctly there is a way to do this within AutoCAD. I just don't understand the SWEEP command options well enough. I've tried setting Align to No and Twist to the 270° that this thing runs, but each time I end up with the stringer rotated out of place.

I work at a car seat company, and we are just now, starting to draw in Inventor. I have problems drawing the seat belt. Here is my first try:
I have tampered with this one! From this angle it looks ok, but it isn't right. I have tried using Loft and Sweep, but with no good results! The seat belt is static in the shown position, but should be able to adjust onto another seat.

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 have tried 2 methods of generating a parapet cap:
1 - Creating a wall style with the sweep.
2 - Added a host sweep.
The problem is that using either method or a combination of both methods doesn't always work. I still end up with some caps that don't miter correctly even after editing. Sometimes, different intersections will miter and others won't.

I'm trying to create a Tiled Skirt (150x150mm) profile or pattern to be used as Wall Sweep. Is there anyway to create this profile as the Family Template: metric profile (wall hosted) only allow me to create a 2D profile.
I would prefer to avoid detail lines or Filled region to get the tiles shown as I need to schedule and quantify this element.

Ribbon has been acting strange. One example is when creating a sweep the ribbon will not show the mode options to accept or discard changes while creating the sweep path. I have to cycle the ribbon display options to show the X and check options to complete the sweep path. This is only one example of many different odd things happening.
Sometimes when I am simply drawing model lines the selection options for rectangle, circle etc do not appear until I cycle the ribbon display options. This only started in the last week or two.

I press CTRL+9 to make the Command Line disappear while drawing. When I plot (or when doing a plot preview) , the Command Line appears again by itself. So I always have to turn the Command Line off manually after each plot
The bug still happens;
- if Dynamic Input is turned off or on
- if I plot to a real device or in PDF
- if the Cammand Line Palette i docked or floating.
This is not an issue in AutoCAD 2012 so I guess it has to do with the new way they programmed the revamped Command Line palette in 2013.
