AutoCAD Inventor :: Extruding Through Curved Surface

Jul 8, 2013

I have tried, such as creating lines in a 3D sketch and projecting the geometry to surface, and creating a work plane, and both don't seem to work for me.... I'm trying to cut out a 5.8mmx14mm rectangle out of a cylinder. When I project the geometry to the cylinder's inner surface, I cannot trim the solid in order to extrude. I've attached the file.

AutoCAD 2013 :: Extruding Curved 2D Surface

Dec 13, 2012

Is it possible to extrude a curved 2D surface to give it thickness? For example, if you were to draw a loop the loop shape but it was just flat, could you extrude it out to give it thickness?

AutoCAD Inventor :: Extrude To Curved But Without Curved Resulting Surface?

Aug 6, 2012

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.

AutoCAD Inventor :: Extruding To Complex Surface

May 16, 2012

I can't post the original files, but I have gotten permission to post jpegs of what I am trying to do.

My end goal is to fill in between the grey part and the surface.  The surface comes from another part in the assembly, and I used Copy Object to get the surface in this part file.  Ideally I would like to do something like Extrude> To Next and select the surface as my terminator.  I have done this with success with curved surfaces, but not complex curved surfaces.  Does Inventor not handle extruding to complex curves?

Another option I tried was simply extending this part out beyond the surface using the Split feature to trim the part.  Again, to no avail.  I also tried creating a subassembly of this part and the part the surface is derived from with this part extending beyond the surface, deriving it and subtracting the surface part so I could use Delete Face with the Lump option.  No dice there, either.

There was a hole in the side of the surface where I am trying to extrude the part (it is still open on the other side of the surface), but I used Patch and it seemed to fill it in just fine.

How to get accurate fill volume data in complex assemblies.

AutoCAD Inventor :: Curved Surface - How To Increase Volume Of Surface At Certain Points Only

Apr 10, 2013

how I can add more volume to curved object surface? Say for example I have a plastic cup.You can think of this as cylinder object ,which was the shelled out using the shell tool and then had its base sealed.

Now at certain parts, I would like to increase the thickness and then blend it the rest of the surface(may be chamfer its edges) .

At certain parts on curved surface I would like to add an extra mm, I think if the surface was flat I would just sketch the shape, then extrude it by few mm and smooth the edges by doing a chamfer

But how can this be done on surface that is curved? Or multi curved for edges?

AutoCAD Inventor :: Ribs On Curved Surface / Trimming To Complex Surface

Feb 28, 2013

I'm designing a press for a skateboard similar to: Rib Press

I have the board modeled: (see attached)

Now what i want to do is generate those ribs as seen in the picture.

I tried creating a block that intersected with the board and tried to split the rib at the surface, but to no avail. I think the issue has something to do with the curve of the board in two directions, but i can't seem to get it right.

if you are having trouble visualizing what i'm asking about, look at this. I want to be able to figure out the exact shape of those center ribs to print and eventually cut out of wood.

AutoCAD Inventor :: Holes In Curved Surface

Sep 30, 2013

Basically I’m trying to create a circular cut in a flat pattern for a hole made in a rolled piece of sheet metal.

I have created a "case" (this is what we call it) to mount an axial fan, it will require holes for mounting the motor plate. When I create these holes in the rolled case assembly they appear to be fine, but when I flatten it they are turned into two sets of semi-circles or ellipses.

This is only a problem when we run the parts on our Laser; the laser will attempt to start the cutting at the end of each of these "semi-circles" causing a hotspot where the two semi circles meet. This causes the hole to be slightly smaller than intended in this area causing great difficulty inserting bolts, they normally require drilling.

 Our material thicknesses vary from about 3mm to 8mm.

I’ve included a crude example of what I’m trying to achieve. To really see what I mean, place the file into a Drawing file and zoom into the hole. I couldn't add the file, with only 3 features the file was 5mb in size.

By the way, I have a temporary solution, it's just a little complicated. (My solution: use square holes first in the un-flat, use the diagonal lines from each corner of the square in a sketch on the flat pattern to place a circular cut on its mid points.)

AutoCAD Inventor :: Extrude Around A Curved Surface

Apr 27, 2012

I have a cylinder that has for lack of a better word, a zig zaged slot milled into the outside of it thru to the bore. I am unsure how to go about drawing this so I can get it to extrude correctly around the part.

From other cad software history, I could draw it on a straight plane and tell it wrap around the part of whatever diameter. But, since I have not attempted this in Inventor I don't know if this exists.

Just for reference, this is a twist lock device. Turn the cylinder, advance a key the is inside the zig zag advancing or retracting the part that is inside the bore attached to said key.

AutoCAD Inventor :: Flattening Part Of Curved Surface?

Dec 22, 2012

I am trying to design a new mold for some sailing rudders I am building. The files I have for the current molds are in the IGS format, which Inventor can open. The current rudders are convex going from the widest part of the foil down to the trailing edge. The goal is to create another model with this flattened. If I were doing this in logic it would be: Find max height, alter foil to be straight from max height to trailing edge. I have tried everything I can do to make this happen with no avail. what would be optimal is if I could get it set up so that I can easily control the amount of convexness to the aft section, but the primary goal is to just get it to be straight. The trailing edge is the straighter one.

The final goal is to export to g-code and send off to a cnc.

I have attached the files after I have imported them into autodesk, but below is a link to the original iges files.

AutoCAD Inventor :: Plane Tangent To Curved Surface?

Oct 2, 2012

I'm designing a part, and am having trouble creating a plane tangent to a curved surface. One option for creating a plane says "Tangent to Surface through Point", which in theory I should be able to use, but I can't figure out how to actually place a point there before in order to create a surface at the point.

Basically I am trying to cut a circle into the curved right side of the part

I've attached the part file for reference.

AutoCAD Inventor :: How To Engrave Words Onto Complex Curved Surface

Aug 16, 2012

In inventor 2013, how do I engrave and wrap some text onto a surface that is neither on a cylinder, a cone, or a sphere? I created the part by first drawing a cross section made up with the spline tool, then revolved it around an axis. I need to imprint two words on the part's curved surface. I sketched the words, then I tried using the emboss/engrave wrap feature, but I got an error message saying that emboss/engrave wrap can only be done on standard surfaces such as cylinders, cones, or spheres. How to engrave words on surfaces other than these standard surfaces? I also tried to extrude cut the words onto the surface, but the words don't wrap to the surface, and are not evenly imprinted onto it. 

Also how do i make the letter's bigger when I sketch them? even though I put in large numbers such as 50 in the size box, the text does not appear big. Also, how do I increase the spacing between the letters?

AutoCAD Inventor :: Knurl Texture On Organic Curved Surface

Jul 20, 2012

I need to apply a knurled texture to an organic curved surface. It cannot be a decal, this is to be rapid prototyped so the knurl must be real 3d. I have an imported Solidworks file that shows exactly what I need. I do not have access to the author of the Solidworks part so I don't know how they did it. Its part of a pistol grip handle.  

Keep in mind that emboss does not support organic surfaces, only cylindrical or planar.

AutoCAD Inventor :: Trim Curved Sheet Metal To Conical Surface

I am drawing a fan wheel. The fan blade is curved intersects the shroud, consisting of two cones. I do not know how to trim the blade to the cones. I tried to "split" the blade at the cones and then "delete face" but then the "Go to flat pattern" section on the ribbon is missing. If I suppress the "delete face" feature the "Go to flat pattern" re-appears.

AutoCAD Inventor :: Making Support And Stiffening Ribs On Curved Plastic Surface?

May 22, 2013

I am trying to make support ribs on a curved plastic surface to make the construction stiffer for a snow puncher. 

(Just like on the attached picture, "pic 1".) 

But I am having trouble doing this over the curved surface towards the top end of the rib.

As is now I sketch the shape of the rib in both ends and loft it over a sketch (see attached picture, "pic 2"), and then revolve to get the ends.

But this gives problems, result is not good and it's very time consuming.

If this was on a flat surface it would be easier, but now I get a lip along the loft and along the revolve on the top end of the rib.

I'm using Inventor Professional 2013 Student Version.

AutoCad 3D :: Make Curved Surface A Flat Surface?

Oct 19, 2011

If you look in the attached PDF, I have an elliptical wall that also has changes in elevation. call it a compound radius if you will. What I have to do is to make a wall cap to go on top of the wall. I know, sounds fun.....I have the surface on the right of the PDF and i need to figure out how i can take that shape and have it lay flat so that i can cut this shape out on my CNC. i know I can use the FLATSHOT command, but this will not give me the true shape of the board.

AutoCAD 2013 :: Extruding / Offsetting Complex Surface

Jan 7, 2014

i need to create a solid by extruding/offseting a spline surface  (attached picture). The problem is, a solid created by simply extruding this surface "outside" would cross itself, so autocad does not allow me to do it (neither extruding, surface offsetting is working) I tried to make a cube then using this surface as a splitting spline - however a solid created this way is flat on z-axis. How can I do this ? Everything is fine with the spline as well as a surface - it's closed one. Obviously the problem is in the fact in the self intersection of the extruded solid. So maybe using it to split a solid is a better approach?

AutoCAD Inventor :: Create Work Axis Where Work Plane Intersects Curved Surface?

Sep 9, 2013

I keep running into a situation where I would like to be able to create an edge or a work axis at the intersection of a work plane and the surface of the part.  I figured out a work around if the surface is flat, but I haven't figured out a work around for a curved surface.

How do I create work axis where work plane intersects curved surface?

Or put another way: How do I project intersection of work plane and curved surface onto the work plane in a 2D sketch?

I need to be able to draw a 2D sketch on the work plane, but get a perfectly matching projected line onto the work plane, from the curved surface, at the intersection of the curved surface and the work plane.

The attached jpg shows the intersection in question.  I circled it.

AutoCad 3D :: Export Curved Surface From 3DS MAX

Jun 13, 2011

I have a curved surface and I don't know a right way to export it. If it like Editable Poly then I have a mesh in DWG. Then I set to Faceted and optimized then merge faces (to receive one face) and then convert to surface but after that I have a surface with multiple triangles. This is one way which I use, I tried many ways but I have the same results.

This is what I have after export from 3DS MAX (same as DWG, SAT, IGS)
