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.

This is causing modelling to slow down as I can not project lines from the sketch that has disappeared.
I have an Ipart I created and in some of the parts there is a swept feature. In other configurations it is suppressed.
The issue is that the 3D sketch for the sweep gets broken going to/from the configuration. The path is generated from an extruded cut that is also supressed.
I tried to recreate the sweep using a different sketch, but that wasn't successfull.
Is this a bug or is there a different aproach I can use?
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 created a shared sketch and have used it with various features. Sometime those features are suppressed. The model works fine but the shared sketch generates a sketch doctor error because the feature that created it has been suppressed. Is there anyway to make the sketch suppressed so it doesn't trigger a sketch doctor error? Inventor 2013
View 2 Replies View RelatedHow do I duplicate the 2D line work from a part level sketch into a drawing level (overlay) sketch?
I started a simple 2D piping system diagram sketch by opening a new part file and using a sketch to stick draw the system schematic including some annotations. Then I opened a new drawing file and made a base view of the part file to bring a view of the original sketch into the drawing.
I realize now that it would have been much easier to have created the schematic directly in a 2D sketch at the drawing level, which would have made editing the annotations much easier at the drawing level, and there is really no need for the part file to exist. I have no intention of creating a 3D model or "real" part in the .ipt file, was just using it as a jumping off point to sketch.
I was thinking that I could correct my error in judgment by just copying the sketch and pasting it into a new sketch on the drawing, but it doesn't want to work that way. I have tried copying both the whole sketch at the browser level, and the entire sketch contents (all of the lines and annotations) from the opened part sketch, but when I attempt to paste either of those into the drawing, paste does not seem to be an option. I'd rather not have to draw the whole thing again, as in typical fashion, my once simple sketch has grown in proportion and complexity from its simple beginning.
I was trying to query some sketch points data from a profile Path using code as below. However the program stopped without telling the reason.
Code below:
i = 0;
foreach (ProfileEntity oSourceProfileEntity in oProfilePath) { switch (oProfilePath[i].SketchEntity.Type) { case ObjectTypeEnum.kSketchArcObject: { SketchArc srcSkArc = default(SketchArc); srcSkArc = (SketchArc) oSourceProfileEntity.SketchEntity; // error points[i] = srcSkArc.StartSketchPoint.Geometry; break; } default: { SketchLine srcSkLine = default(SketchLine); srcSkLine =(SketchLine) oProfilePath[i].SketchEntity; // error points[i] = srcSkLine.StartSketchPoint.Geometry; break; } } i++; }
First we imported an ".igs" file to inventor, which produced "wires". Then by promoting the wires it produced a 3-d sketch.
The model is in one plane and 2-D, and we are trying to use Ansys 2-D analysis, but in-order to do so it needs to be in a 2-D sketch.
The model is too large to be redrawn on a 2-D plane, how to convert it to a 2-D sketch

View 1 Replies View RelatedOn 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.
View 3 Replies View RelatedI have looked through these forums and found plenty of sweep problems and the answers to the problems but none for this particular type.

View 9 Replies View RelatedTrying 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.
View 3 Replies View RelatedI 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.

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.
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?

View 3 Replies View RelatedI 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.
My purpose for Inventor (2012) is for cabinetry, more specifically the majority is for kitchen cabinetry.
All of our kitchens have crown, but not the same crown profile every time. There will be dozens of profiles if not reaching 100 or more.
What I am trying to accomplish is a way to model a sweep (which I can do no problem) but I would like to have the option of changing the sweep profile on the fly. I would be sitting with a customer and they would say "yes or no" to what they like.
I have looked at derived parts and iFeature and unless I am missing it, it's not giving me what I would like. Is this where iLogic comes in? How to use that, which I know I will have to eventually.
Right now I have an .ipt file with 7 crown profiles. Not sure I want to go any further for fear of re-work.
