AutoCAD Inventor :: Plywood Boat Plank Unfold
Dec 28, 2012
I am drawing the hull of a plywood hard chine boat with Inventor.
Basically there are a number of boat stations that are drawn in as sketches on parallel and spaced planes. Stations are drawn as series of straight line segments representing the hard chine technique used for this particular boat.
The plank is created as a lofted surface passing through each corresponding straight line segment of all stations.Surface is then thickened and it becomes a sheet metal.
I am unable to unfold or better to create a flat pattern from the sheet metal. The program correctly complains about the lack of bends in the sheet metal: there are infacts no bends as the plank is a continuous curved surface of which I would like to obtain a flat template for CNC cutting.
I doubt the problem comes from compound twisting/stretching of the surface since the stations' geometry comes from an existing design of which several hundred plywood boats have actually been built.

I have a model of a plywood seat "blank" which I have trimmed by way of an extrusion cut to give the plywood seat its shape. Basically I'll use my modeled shape to CNC rout the shape into the actual blank. However, before I tie up a CNC to make my 1st part I want to create a flat pattern which I will lay on the actual plywood blank and cut it out by hand to see if the shape aesthetically works. I am trying to unfold/ unroll/ flat pattern the shape in inventor (as a sheet metal part) so I can plot it but am not able to do so successfully (fails). Is the shape to complex? I have attached an image of the blank, an image of the finished shape desired and the .ipt. I'm not an expert at sheet metal but I have successfully done this sort of thing before making flat patterns of transition cones etc so I do think I am following the correct procedure but this part is far more complex that I am used to. Also, the model of the "blank" was imported as an iges from my supplier before I made it a thickened surface so I'm afraid inventor doesn't "historically know" how it was created and therefore cannot flatten it.

I have never used the unfold command before. It seemed simple enough, draw the part, extrude, turn into sheet metal, set defaults and unfold to make a flat pattern. It will not let me unfold. The dialog box comes up, but will not allow me to pick a flat surface or bends....

I'm having an issue with some similar pieces of sheet metal. They are created with a face, then I place a fold, then I need to unfold/refold it so I can place holes while it's unfolded and have them remain as true holes.
2 of the 3 parts do this just fine, but one particular will unfold normally, but the refold, even though it succeeds, does not actually do any refolding, I'm just left with the flattened part.
Every sketch is fully constrained. I've experimented with changing the sheet metal rules.

I want to creat a hollow cylinder. But I need to be able to unfold it to have a layout of the cylinder. So that when this DWG goes to the floor the technicans knows how much he/she will need from the sheet to roll the cylinder.

Is there a way I can tell Inventor which folds to fold or unfold when creating a flat pattern? I want to bend some C-Channel INWARD and Inventor doesn't seem to be able to do that. When it's formed C-Channel, I can bend the legs and all that but I don't want those legs to unfold when I create a flat pattern.

A lot of times our customers will send sheet metal parts for us to manufactur. unfortunately they do not have inventor and/or do not, or won't, send the flat layout. It is possible for me to convert these 3d files into Inventor sheet metal pieces and lay them out so i don't have to re-draw? What are the steps to do so?

I have a conical shaped part that Inventor 2012 will allow me to unfold, but will not refold accurately. When the refold is complete it should roll back up and be .01 degrees from completely round. But instead it leaves about 60deg of opening. I need to cut out 120+ slots out of the face of the metal, but once I do this while in the unfolded state, it will not refold at all...not that it owuld matter if it, seeing as though it refold inaccurately.

For some reason I cannot unfold sheet metal product on attached file. Where have I made a mistake? I used extruding, also sheet metal thickness from rule has been set to 2mm. Rest are default values.

I'm looking to unfold the attached sheet metal elbow and am unable to do so. After modeling the part I was also unable to rip an opening to split the part. I opted to cut an opening with a profile, but I am still unable to unfold the part. The probelm is likely obvious and I believe it is because I used part splits to create the different sections.

I created a part that spans between two other pieces. The original part model does not have a twist in the "flat" surfaces, so it unfolds just fine, but it also does not represent the way the actual part fits, so it is difficult to determine if any other parts are fitting correctly up to it.
I had a problem getting a part to unfold before, and I was shown a method of creating a surface body and a thicken, which I have done with this part, but as of yet have had no success unfolding this part.
Is there anything that I can do since the sides are twisted and not planar?

Automation of the sheet metal bending parts unfold /refold in vb.net for Inventor 2013.
I want to unfold the part with selecting the one of the face as stationary face and further selecting the bend/ bends with reference to face in vb.net
For refold, I have to select the stationary reference automatically , based on some criteria, and further to select the single and multiple bends by using API.
Also, I want to find the bends and faces relationship i.e.
How to find the bend associated with number of faces, how to find face entity using internal name ;
The code I tried I am attaching here for your reference.

I need to desiign a "rooster tail" effect for a boat designer's web site.
I guess I can best describe the vision of having a boat cruise across the intro page screen with the wave it creates behind it.

I have spent some time over the last few days attempting to create a boat hull by lofting sections along a line representing the center line of the hull, but I'm not having much luck. The shape that is created appears to be rotated some weird way, and I just can't seem to get a handle on what is going on. The section splines were created in the Front view, the path was created in the Top view. The section shapes were then placed in the Left view to correspond to their location along the hull.
My question is this: where can I find a tutorial that deals with boat hulls and lofting specifically, or failing that.

I'm trying to use iLogic Design Copy to copy an assembly and all its associated parts to another directory. The assembly contains content center parts. Inventor warns me that the destination file of one of the CC parts (and 18 others) will be overwritten. When I go ahead and copy anyway, the copying process stops at that specific CC part. The Design Copy Progress dialog box states there is an error copying that CC part. When I close the Design Copy Progress dialog box, Inventor crashes.
The error copying the CC part: I'm allowed to use content center parts in iLogic Design Copied stuff, right? I searched some related topics and I'm under the impression that Inventor keeps the CC parts in its own directory and shouldn't be trying to overwrite them.

We are trying to get task scheduler to automatically download certain files from the Vault. Templates and Styles. The templates work great, but there is no way to specify any filetypes other than Inventor filetypes. Am I missing something? Is there a way to specify non-inventor filetypes?

Upgrading to a new computer.
1. What is the best CPU to use for Inventor between the i7 and the a Dual Xeon System
2. Would 32GB of memory easily cover all modelling such as assemblies?
3. Any advantage of having 2 x SSD instaed of 1 x SSD
4. Looking at the Nvidia GTX690 graphics card....this should be a good card

So I installed TD Inventor Professional 30-Day free trial and I downloaded the installer and went through the download of the installer process and it made an autodesk inventor folder on my desktop. I click on it and it takes me into the C drive under the autodesk file Inventor 2012 TestDrive and has an Application called TDSetup. Once I click on it it does a load wheel then nothing happens.
I can't seem to find a solution and I just installed DirectX.
