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.
View 2 RepliesI 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..
View 5 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".
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.

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 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 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 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 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.
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.
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.
View 3 Replies View RelatedI 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.
I have this part that need to be extrude along a complex path. However, every time i try this the bottom of the part does not stay parallel the the x-axis.

I have a sheetmetal assembly with helical shaped parts. I need to place about 50 little brackets and some corresponding rollers along the length of these helical pieces. The spacing is even so a pattern would be perfect, except I don't know how to get it to follow the shape of the part. The brackets are located to slots in the helical parts which were made with a rectangular pattern in the unfolded state. I tried to do a "feature pattern select" but it only saw the rectangular pattern as it is in the unfolded state (a straight line). I then gave up on patterns and started working on manually mating them into place but realized that the geometry of the slot was distorted (theory) and didn't leave me with any useable surfaces.

View 9 Replies View RelatedHow 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).
When showing a gear in an inventor drawing they look good, but showing a helical gear SUCKS! The display, I realize, is very realistic to what you would see if you held the gear in front of you at this view point or that.
Problem is, I put a helical gear drawing on the shop floor and they machinist wonder why I have two rows of teeth on the gear (since it shows the front face and the helix'd gear teeth).
Any way to remove said offending gear teeth?

I created a 2D planar sketch, now I need to create a 3D sketch and Helical curves, but as I enter into the 3D sketch mode, I cannot perform any functions, all my tool bar options are grayed out?
I am running 2014 Pro Design Suite.
I have created a bin/vat/tub using sheet metal. I started with a contour flange. I then copied the sketch and pasted into a new sketch off the flange for a contour roll feature. Then a flange, roll, flange, roll, flange and roll. My trouble starts at the last flange. I'm trying to construct the flange exactly as I have created the features before. I set the distance, select the profile (it shows the flange on the screen), hit apply and that's when my message shows up. "Non-tangent curves found in path: flat pattern cannot be correctly created. Edit sketch and add constraints to the curves. The sketch is fully constrained according to the lower right hand corner and the auto constrain button.

I have generated a gear set using inventor. Now I would like to 3d print the gears. I have uesd the export tooth shape to get the true tooth profile. now I am attempting to use the coil feature to generate the helical tooth. The problem im running into is in the coil tool I can only give it a Revolution and height dimension. The hight is the width of the gear, but I am having a problem converting the helix angle to the "Revolution" perameter. I have read other posts and they say that it is Helix angle / 360. I have tried that and then compared it to the original gear generated by inventor and it is not even close. I need to do this on in internal gear and match it to an external gear.
