I'm having a problem sweeping a curved object over a spline. The object will sweep over a straight line...but not on the spline. I keep getting "unable to sweep object(s)" in the command line. I could be doing it all wrong... I've attached the file.

View 9 Replies View RelatedI am trying to create a tube by sweeping a circle along a spline. I read many of the previous discussion threads on the topic but I still have some issues.
I first created my spline and transformed it in a polyline (some people recommended to do it). Then I created the circle. Finally I sweep the circle along the path.
The issues are the following:
1) when I look at the tube using the 2D wireframe mode, I can see that the primitives are not completely regular. In some points there are weird intersections and I don't know how I can fix them.
2) I hoped the tube was solid. However, when I exported (as .IGS) it and see in another program, I realized that it has only two circular caps at the extremities of the tube, but inside it is hollow.
I tried to transform it in solid or mesh or whatever, but it always gives me an error, saying that the object cannot be converted.
Code to convert a spline or read its points so I can create a curved leader (with arrowhead) reasonably close ?
View 9 Replies View RelatedHow to curve a piece of sheet metal over the outside curved edge of the attached part. I can do it the old fashioned way but was wondering if it could be done in sheet metal which would give me the flat pack automatically (that way there is less chance for errors). There are several of these baffles joined together by a spine and the sheetmetal will eventually go over all of these, and have a few modifications to shape the end profile.
The outer curve is a spline which has changing radius and hence to use a contoured roll would be rather difficult and time consuming (there are also some flat sections at each end of the curves as well).

Basically I have 3dpolylines and some Splines. I would like to create a road file that uses the geometry of these objects to create a single line/crest of road file.

I drew a simple zig zag spline, extruded it, gave it shell for thickness and when I boolean substraction A-B i get 2 halves but without the cut walls- they appear empty. I need the cut to appear as if through a solid object.
Do I have to rebuild those cut walls by hand to make halves appear solid, or is there a faster way?
I'm trying to create an external involute spline (ANSI B92.2M) Fillet Root Side Fit 26.9mm x 1 mm x 26 teeth x 38 mm long using the spline generator with Inventor 2012. I created a test shaft"M-182-AMA.ipt" that is Ø26.9 mm x 38 mm long with 1 mm radius on each end of shaft.
I use the following steps:
1. After creating component "M-182-AMA.ipt" I select Design tab>>Power Transmission>>Involute Spline.
2. A window appears that has the caption "Involute Splines Connection Generator".In the Dimensions section I choose "Splines Type: ANSI B92.2M - 37.5 deg, Fillet Root, Side Fit, 26 x 1.00 x 38 x 5H/5h" and change the Length to 38 mm.
3. In the Shaft Groove section I use Create new, and I push the Reference 1 button that turns blue, I then select the od feature from the model and I get an error(see attached pic "error1.jpg).
I changed the 26.9mm od to be 27mm and it still gave me the error.

I have to animate a long tentacle like object eminating from something , wrapping around another object and pulling it backwards. I have been looking at splineIK,pflow and some other approaches but they only cover part of the animation I need.
I am playing with PFlow and I can get something to spawn along a spline path to wrap around the object but not sure how to simulate the thing retracting and pulling the object with it.
I know there must be a better way to do this.
I am trying to use a spline to deform hairs on a object.
I have 1 editable spline, with multiple splines attached to it(1 spline which has been rotated), but when I use it to comb the hairs, it will only take 1 or 2 of the splines, so it all goes in 1 direction, rather then all outwards from the center, like the splines are.
The splines are all the same, all in one shape, and all have the first vertex in the center.
I have tried re-creating the splines, but it comes out the same.
Script to clone an object along a spline so that if i modify that spline vertices all the clones are repositioned automaticaly?
I use to apply a Path Constraint to initial object position and then i call Tools|Snapshot to clone it, but this works just for distribute the clones. The path is relationed just to original object, not to the clones...

I'm trying to slice the grey cylinder object in the attached drawing with a curved network surface. Rather than slice around the path of the surface it seems to have just taken a planar slicing plane between the 2 vertical edges of the network surface.
i'm applying an extrude modifier to a simple spline shape, and i am accustomed to the extrude modifier generating a solid 3d object in the shape of the spline, if the spline is a closed shape.
however, in this case, the extrude modifier is generating just a 3d outline based on the spline's shape...
i can't figure out why i'm not getting a solid 3d object since the spline is closed (i checked all the vertices).
file is attached (the spline in question is named "upper side section")

View 3 Replies View RelatedI am trying to create a CAD drawing for the construction of Paddle Pop sticks. It is the basic shape of the Magnum sticks, but it is tricky because it has a 140 diameter taper, from the top of the jig to the bottom. I am trying to make the circle attached to the shape of the stick, and the Sweep the circle around the shape. But when I try to sweep it around, it says "The sweep results in a self-intersecting circle". I am using AutoCAD 2012.
P.S. I have attached the .dwg file so that it makes more sense.
I am modeling an ASME pressure vessel with a 2:1 semi elliptical head upon which there must be a couple of lines of .375" trace tubing. I created a 3dpolyine that is the center line of this tubing, and joined all the segments into one so as to be able to sweep the whole thing and make one solid of the tubing run, but it simply will not sweep. I get a message this it is "unable to sweep the selected object." If I break the 3dpolyline, I can sweep parts of it, but the more complex the line segment, I again get the error message. I have attached a copy of the tubing centerlines.
The one on the left is the joined 3dpolyline, the one on the right is the 3dpolylines unjoined. (These were achieved using an intersection command of a rotated surface--the head profile--and an extruded surface--the tube tracing plan layout.) I have done this before, but only with the unjoined 3dpolyline, as in the right-hand example, but that is very time consuming as each segment must be swept. But I recently acquired a third-party LISP routine that joins the 3dpolylines into one. I'm thinking there must be a limitation on data of the 3dpolyline preventing the sweep, and wondering if there is a setting or system variable that will allow the more complex 3dpolyline to be swept.
How to use sweep to successfully put threads in a hole. Attached is the drawing with a helical coil and an object in two different orientations (A and B). To the right of that, you can see the path they took for each. The object rotated from the original position before following the path. Tried changing the position of the object to sweep, but either it sweeps it 180 degrees from what it is already doing (still wrong) or the program says it is invalid and won't do anything till I put it back in the original rotational position and try again.

I've a vague notion that this could be done with a dynamic block and a few fancy expressions. I'm comfortable with expressions, but I've never used dynamic blocks at all, so I wouldn't know where to start.
To be clear, I know curved text is possible, but I'm looking for a curved line (ie an arc) that would look 'parallel' to the arc of the feature line (ie have the same centre point). This would have to be dynamic to allow for different radii and for flipping to the left and right side of the feature line.
I want to extrude a big number of pillars to a rather complicated surface and that works out fine. But each end of the pillars warps around the surface and I want them just to go up to it and stop with a resulting horizontal face.

View 9 Replies View RelatedI'm trying to wrap an image around a curved object. This is a front elevation of a sign I am attempting to render and the sign wraps around a pole. What I am attempting to do is not just "squeeze" the copy but actually attempt to show what the image will look like if you are looking directly at it which means that the closest portion of the image will look normal but as you look further out towards the edges then the graphic and copy would appear to merge and disappear backwards. I hope I am explaining this well. I am trying to wrap my brain around this concept. I know you can do this in photoshop with stretching but cannot fathom how I can attempt this in CorelDraw or Illustrator.

I created one, then arrayed, but the radius changes at each 2.5 degree interval. I don't think I should have to calculate the % radius change to get the beams to do this. Some constraint button maybe?
Not sure if editing a wall profile is the best way to model this, but it's working.
I am currently working in a facade that has a stylized gondola on it. The gondola has curved walls for the sides, and I need to have the curved cut to give it the shape. The tools I know are for straight walls, not curved. and the Opening/wall makes a squared opening, not curved.
