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.

I often have to do storm pond surfaces that (for the purposes of planning) are flat on the bottom. These surfaces are created from a combination of survey data and grading groups and the tin of these surfaces is perfectably acceptable. However, when contours are shown, the flat bottom is shown with contours jig-jagging all over the place.
The attached image shows a comparison of the same pond. The top was created with survey data and grading groups; the bottom was created using contour data only. The generated surface on the top shows the bottom contour going in different directions and has parts where the an expected contour is missing.
How to correct/manipulate the surface to show a proper flat surface?

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?

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.

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.

So I need a starting point on how to draw on a curved surface.

how to draw the "slot" I know in solid works i can "project" onto the surface and then so a cut.

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)

This is what I receive from splines and loft in AUTOCAD.

running an assembly in to the road corridor and creating a surface. i have designed a network of Roads in CIVIL 3d in which whole network is surrounded by a Loop road. The loop road cross fall is unidirectional (2%) and 4.5 wide. I have used LaneOutsideSuperWithWidening subassembly to create the assembly of the road. This doesnt contain any kerb or footpath but only road channel lines, The corridor run soomthly but after creating the of the loop road corridor the surface is becoming flat meaning there isn't any cross fall acoss the road but in the assembly crossfall is there. If i run the same assembly in another road alignment the suface is coming absolutely correct.
I also tried different road assemblies to run along the loop road but the result is same no cross fall across the road.

I'm loft retarded. What I did here was loft to a tangent work plane, then did a sketch on the top surface and extruded the shape that I want. There has to be a better & easier way.

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?

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.)

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.

I'm using AutoCad 2007. I'm trying to map a simple 2D flat drawing onto a curved surface.
I have a 3D drawing of a very simple curved floor, similar to a skateboard ramp or a photographers infinity curve backdrop. I also have a 2D design. I simply want to drop my 2D drawing onto this curve, so that it follows the geometry of the curve's surface.

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.

I would like to map an image to the face of Inventor part document. Which possibilities Inventor API offers here? I checked out the ColorMapping example but the tessellation of the flat surface is not sufficient to get high resolution image mapped on it. My intention is to attach images to several parts faces within the assembly environment and this as fast as possible since the scene needs to update very quickly.
PS: I use C#.NET.

I am using Civil 3d 2012 and an trying to apply elevation banding (one color) to a surface that is completely flat. Everything seems to be in order but nothing shows up. If I add another point file to it that has a variety of elevations then the elevation bands show up, if i remove it it disappears again. I can view the boundary and get elevation readings when I mouse over the surface.

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.

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.

I do a ton of rendering for my work. We have many curved surfaces within our product line. My problem is that, A lot of times my materials (jpeg's) warp and blur when added to a curve. My guess is it has something to do with the UCS orientation because if i rotate the curve to be parralell with the current UCS, the material shows up how it should, Until i change the UCS back to world.
Same Image material, Surface on left is curved and surface on right is flat. Warp.jpg

Is there any way / trick to wrap a 2D sketch to a non-flat/cylindrical/conical face? See attached part. I'd like wrap the lines in Sketch2 to the ring's outer face in order to get a proper path for "engraving". I see no other way to get a proper path for sweep, because project along vector won't work.
