AutoCAD Inventor :: Sweep Imported Structural Profiles?
Jan 7, 2014
I want to sweep a I-beam along a 3d sketch to create a conveyor. I will be using different shapes at times so the profile won't always have the same shape, sometimes a small I-beam or a large one or possibly square tubing.
I know I can create the profile and dimension it but is there an easy way to import the profiles from Frame Generator into the sketch or another way without having to create and dimension the sketch? Or is this one of those tasks you just can't avoid?

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?

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..

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".

How do I get to the settings that control what does and does not show in any given discipline - we need to update the Structural Discipline to show the non-structural walls, and non-structural portions of other walls as halftone.

I've been working with inventor professionally for about a year now doing piping and vessels for the oil field. This also involves a lot of pipe supports and platforms.
I'm trying to streamline the process right now by coming up with a way to make some adaptive bracing that I can reuse so I don't have to model it over and over. Most of the engineer drawings I get are basically the same; 2d lines for beams with work points for the bracing and typical connection details.
I start with a skeletal model and use frame gen to drop my beams in. But bracing is where I run into difficulty. I get it done but its just tedious and time consuming
Is their a way I can make a reusable adaptive or flexible bracing for this task? Here's some pics of what I've been sinking around with to try and automate this (I haven't found a good solution yet).
1. Created my skeleton
2. Dropped beams in
3. Created bracing template
4. Dropped bracing temp in assembly
5. Constrained it into place
6. used make parts to place the gusset plates into my assembly
7. gusset plates fully parametric
I'd like to have a better process of doing this. Ideally I'd like to drop a whole brace sub-assembly (gussets, brace and bolts) in to the main assembly and constrain to the drawing specified work points and be done with it.

Using Inventor 11 I wish to create some individual parts using Structural Shapes from the Content Center as the basis for my sketch profile and extrude to length before doing other machining.
Is it possible to do this from the Part environment directly and not use the frame generator?

Is there a method of extracting XYZ data to use for CNC tube bending from components developed in frame generator ? I know that in routed systems you can export that data, but can the same thing be done with frame generator or any individual bent tube or pipe part?

I created a structural shape profile for use in a project. It is square tube with radiused corners, very similar to "ANSI/AISC (Rolled Steel) Structural Tubing Square" in the content center, but mine is 1 inch square with 0.065 inch walls.
I've made a chassis out of my custom tubing. When I run a frame analysis on it, I get an error/warning stating that the torsional section modulus is zero, because I didn't fill in the value when I generated the frame. How do I calculate that value?
I've attached the tube that I used to make the structural shape.

I want to create frame made out of structural steel. In order to do that Invwentor is giving me no option but to make Layout Sketch (any other way?), which then i should use for inserting members. Now, when i want to creat layout it does not give me an option of assigning it to a work planes i created. It always sketches it in default XY plane. I need to create 3D layout that will follow several work planes i created. I tried selecting any of the other work planes before clicking on layout button but no luck.

I have created a few new structural parts that I am in the process of publishing to the content center.
I got one of them in and have it working very well except for one item. If I place this structural piece into an assembly as a stand alone part just selecting the length and the material as the key inputs, it shows the proper length in the part number and the description just fine. If I insert this same structural piece in a skeleton using the frame generator, then the length that shows up in the description is the default one that the part was originally created to. How do I get the length to show up in the frame BOM correctly when parts are created using the frame generator?
This works using the structural members out of the box.

I'm using 2012 Professional and I would like to know if there is a way to insert a structural member into a part file instead of having to use Frame Generator to get structural shapes from the content center withough having to manuall draw the section view of the member..

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.

In the image below, I need the C channel that the bolts are going through to section but not the nuts and bolts. In application options I have "Section standard parts" set to "Obey browser settings". In the part "document settings" I have the "participate in assembly and drawing sections" option checked, but the C channel will not section and when I right click on it in the drawing browser, the "Section participation" options are greyed out.

When I insert a standard 6" square tube into an assembly there are all of the custom shapes and standard structural members to choose from. When I try to put the same tubing into a part file only the custom shapes are visible and no standard parts to choose from.
I can only guess that I have some obscure check box missing. There appears to be no good reason why I would be restricted in part files.

I am working on creating custom structural steel content libraries for our company. One thing that I would like to do is to have the content center create a new part with the xy plane as the midplane of the resultant part. By default, the xy plane is at one end of the part. I turned on the xy plane in the part shown in this screen shot.

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.

I tried the tube and pipe run to build this segment, and cannot select the route from the 3D sketch.
This route was based off of a 3D sketch made from included geometry from another part.
Tried sweeping too - and get error that the sweeping operation did not produce a meaningful result.
But I don't get the self intersecting error.
All this is is a .250 OD and .180ID profile that needs to be run through the path.
I included the part 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.

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 used to use Solidwork's sweep-cut with a solid body feature but i can't find it in Inventor now.
Procedure:
In part file;
Create a second solid body (must be axis-symetric, like revolved feature),
Create a path that intersects with the solid (can be a line or a curve),
Sweep the solid along the path with cut command.
I need this where the sweep-cut with a profile is not enough, to get surfaces obtainable by milling on a cylindirical body on a helical path.

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.
