AutoCAD Inventor :: Sweep - Trimming And Discarding Faces Error
Sep 26, 2013
I'm trying to sweep six circles along 6 3d sketches however I receive the 'The attempted operation had problems trimming and discarding faces. Try again with different outputs.
I have been suffering with the above error message and i am at my wits end. I've tried tracing the the geometry, played dot to dot joining up the points but to no avail. Some sweeps work and others don't.
how to cut or split more than one face of a surface model in one go. The only way (it seems) is to use the Trim command for every face you need to trim, whereas I want to choose the cutting tool (a plane or face) and then choose a whole lot of faces (by holding CTRL and clicking the faces) and trim them all in one go. Is this possible? I can do this in Fusion, but Fusion is way too slow on my PC compared to Inventor.
I also tried extruding a sketch through the surfaces to cut them, but it doesn't work (Inventor complains that there aren't any solids to cut).
I have two faces of different size and am trying to sweep out a curve section between the two. But since the two faces are of different size it only follows the path with the original face selected.
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 created a solid, shelled it, and then converted to sheet metal. I am now trying to indentify the bends but I am getting the error: Bend 1: Could not build this Bend; No matching faces found.
i got Inventor recently, and i've been working on a model of a longboard just to teach myself how to use the tools in Inventor. right now i'm trying to color areas for the griptape pattern so i drew the 2D pattern and projected it onto the 3D model of the longboard. but when i tried to split the faces of the model along the projected pattern only a few of the projected lines split the faces. for other faces i kept getting these errors:
Create parting line failed Crane.ipt: Errors occurred during update Split11: Could not build this Split The attempted operation did not produce a meaningful result. Try with different inputs.
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".
So I make a line and then make an arc on that line. I dimension the arc so that it is 180 degrees and I dimension it with a specific length. I then use the rectangular pattern command to copy multiple arcs onto this line. I now need to trim the bottoms of the arcs away (the parts of the line under each arc) But once I select the trim command I cannot trim this area! The lines I need to trim won't even highlight. It appears they are locked by a dimension made when I copied the arcs across the line. This dimension doesn't appear to be able to be deleted.
I need to trim a part that intersects with many other parts in several different sub-assemblies - on an angle.
**Attached is an image of my problem.
Split tool is disabled. It is only usable once I drill down into the assembly/part - it will not select the other cutting objects higher up the browser stack.They become ghosted.
What I need is a tool that projects intersection lines. Does Inventor have something like this? Standard projection lines on the part is not working because the cutting objects are not 90 degrees angled to the part to be cut.
This may be easy,.. I am just not seeing a way to do this with out a bunch of work-a-rounds.
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.

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.
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.
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?
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 am practicing modelling 3D sweeps using an intersection curve, and tried to insert a swept cut on the attached model, but the ends are not circular. I assume this is because the plane which I drew the sweep profile on is not on the top face. Is there an easy way to rectify this and create the semicircular channel in the ends?
