I want to make a sweep around an ellipse shaped path. Somehow when Inventor is asking for the path it does not want to select the ellipse.
When I try in 2011 it does. Try in 2012 with attachment, no luck
i'm using Autocad2012 now. when i use paste special in objects and give x or y insertion scale. after i do explode that object the arcs are converted in to ellipses and it come with ellipse grips. before 2012 version it won't happen. what's the change in autocad 2012? is there any variable to change?
View 3 Replies View RelatedI 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".
We have been generating technical illustrations using Mental Ray in Maya 2011 with brilliant results. The studio upgraded to Maya 2012 and we now find that when we render any existing scenes, or any new scenes using entirely Maya 2012 nodes, we don't have any contour lines.
Our scenes are setup as follows:
Materials - Contour_Shader_Simple.outValue > ShadingGroup.miContourShader
Cameras - Contour_Composite.message > Camera.miOutputShader
Render Globals - Mental Ray Tab > Contours > Contrast Shader > Contour_Contrast_Function_Levels
Render Globals - Mental Ray Tab > Contours > Store Shader > Contour_Store_Function
why the scenes now don't have any contour lines?
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.

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.

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.
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.
I'm having difficulty with a sheet metal part creating a flat pattern for it. The shape is an ellipse with the dimensions shown in the second picture. When I attempt to create a flat pattern it just shows the side of the part. The sheet metal defaults are correct for the part and it was ripped to created a base point for the pattern. I need to create a DXF for manufacture. I would just use the flat pattern it gives me and mirror it twice to create a pattern but it doesn't factor in the radius of the part. How to create a correct flat pattern for this item?
View 5 Replies View RelatedIs 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.
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 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.
View 7 Replies View RelatedWe 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.
View 2 Replies View RelatedI'm trying to dimension an ellipse in the Inventor Drawing Feature. I've attached the .idw files. (the .ipt is too large)I am aware that the ellipse doesn't have a constant radius and was wondering what is accepted practice for these dimensions?
I need to first dimension the external elliptical shape (which I'm struggling at), might just add a note.
Secondly I'm trying to dimension the mesh part, its not centrally align to the part and since I can't put a center mark on I'm not sure how I should dimension this...
I'm trying to use the equation curve to draw a super ellipse.The formula I'm trying to translate for inventor is the following.I'm guessing this should be possible using the abs() for the first section and an IF() statement for the second. The problem is Iäm not even getting the abs() to work at all. How to translate this formula?

However, as I did not create the ellipses on the faces, but the ellipses are just the result of the projection of an empty egg inside an extruded rectangle on the faces of the extruded rectangle. How can I see the dimensions of the ellipses? I tried to use the measure distance command, but with no success.

View 4 Replies View RelatedI am having trouble creating an extrude-cut from an offset ellipse. It seems that when the ellipse is offset, it becomes an associative spline. I need it to remain associative with the original ellipse.
But, when I try to extrude a profile using the new spline, it won't recognize the edge.
I can't just create a new ellipse, as it's profile won't quite match the offset one. I tried tracing over the ellipse with a spline, but it then requires a vast amount of dimensions to constrain it all together.
I'm trying to extrude-cut the red outlined profile (including the elliptical part of course)..
Here is the part. I am working in Inventor 2009.
Im struggling coming up with a loft or sweep to get the design effect I need. see on the pic how the profile terminates to a point.
View 4 Replies View RelatedI 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.

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.
