We're seeing strange behavior on all of our workstations when using a Refold feature on a sheet metal cone. Surfaces are (very incorrectly) being added at the top and bottom openings of the cone when the Refold feature is added. The behaviour is the same whether using Contour Roll or Revolve. The surfaces dissappear when the cone is revolved to a lesser degree, such as 200 degrees instead of 359. The cone can be revolved to 360 degrees and ripped but that raises a whole nother problem because Inventor does not correctly refold a 360 ripped cone. File attached. By the way, the surface artifacts show up in the flat pattern as well.
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 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.
I modeled a sheetmetal part, saved it and then did a save as to make a similar part. I changed a couple dimensions and when it updated it chnaged it's orientation. Playing with the EOP marker reveals the refold feature, the last feature in the model, to be the culprit. I tried reentering the stationary reference, and I tried deleting and recreating the feature.
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 am currently using AutoCad 3d 2011 and i am trying to add some graphics (bmp. or jpegs) to surfaces. In model space when materials are on the graphics are there. When i go to render in the graphics come out grey. However if i change the lighting settings to American lighting units the graphics then appear when it is rendered. Why is this? I do not like using American units as it always makes my renders appear washed out.
How graphics can be seen in any of the other lighting units? or why this may be happening?
I was working in CAD wire-frame and I'm drawing a small plate 230*60*15, is there any way to turn this into a solid object or add edges to it, so it appears as 1 object?
I realise you can draw a simple 2d line and extrude the edges but what i want to know is can you add surfaces to the wire frame.
Is there a way in Inventor (or any other Autodesk Design Suite program) to find the point on a cone (attached jpg) where the lifting lug should go so that when lifted, the cone stays in the same orientation as in the attached picture.
I have a cone shaped part and would like to put a hole in the curved face. I would like have to hole square to the face in the flat pattern so it can be cut on the plasma table, is there a way to do this? I attached the part with holes in the approximate location.
How to draw with sheet metal rules centric cone? Ive spent hours on it and nothing, it always end up on ASM failure, or ceates the only one half( when sliced on asymetric way). This need to go in two halfs.
Ive tried:
two circles 1300 and 300, top circle centre moved from Y by 127mm on X axis.
contour roll will revolve on axis between circle centre points, than extrude something with cut and it is but the shape is an oval not circle.
Ive used loft command and slice command but only one side picke will work with flat pattern.
Trying to model a car dashboard, not the wheel or gears but the big shape you hit your knees on if you sit in a car. Following some simple box modeling to get the basic form, apply turbosmooth, add some edge loops to get the right amount of curvature on some edges, great.
I'm miserably failing the next step, which is adding in details like lcd screen and vents. But even something as simple as making a crease that goes left to right across the whole vehicle, since those loops end up breaking the smoothing and the nice subtle curve is gone.
So next I tried geting the basic shape and adding an edit poly modifier on top then another turbosmooth on top of that. But it's getting very out of hand with the amount of faces.
Another idea was putting in the detail first on a flat plane, then using FFD 4x4 to bring the curve back, but then I'm not able to pull out the pieces that came from the box modelling method, how the armrest area comes out from big piece itself.
Am I missing a method of doign this? I don't want to have to resort to just unwrappign it and adding my details with a normal map. I want to use real geometry, and I've seen some great models in the past with this kind of detail, but don't know how to get there.
I want to engrave the text 'TEST' all the way around this clonal object. When I use the emboss tool, selecting the option 'wrap to face,' it gives me an error message that the "face selected is not tangent to the profile plane."
I am using a work plane that is offset from the XY plane. I included a screen shot and the file that I am using (Inv. 2014)
I was performing some FEA analysis and was getting some strange results. So I investigated into my material properties to find that mine were INCORRECT! I looked at some of my co workers material libraries and they seemed to be correct. How do I go about possibly resetting my material properties. I just installed inventor 2014 about a week or 2 ago. I have attached a screen shot of the incorrect material properties.
I'm using Inventor 2013. I created an assembly where I did a lot of top down modeling (meaning components in the assembly were created in the assembly. All but a handful of the components are adaptive to other components). When I went to make my drawings for having the components made, I started noticing that some of the dimension values were wrong. I could go into the model and verify the features, but when dimensioning on the drawing it would not match. Furthermore, this didn't occur on every dimmension on the drawing. Not even half of them were incorrect, but it only takes one to really mess up a part.
I've attached a screen shot of what I'm seeing. The 15.2 and 5 dimmension are correct, but obviously those don't add up to 31.37. I know I can manually override this dimmension, but only if I know to do it. I tried to do a drawing of another part in the same assembly and eventually found a similar problem.
Finally, I created a step file of the 1st part (to strip away the adaptivity) and when I created the drawing again, the problem went away.
My question is, is there something I did in the assembly / creation process that would have caused this?
When i attempt to open an IGS file i get "an unnnamed files contains an incorrect path"
I thought it could have been a corrupted file but its not.Tried to create my own IGS file (successful) attempted to open that and failed.Downloaded an IGS file from Autodesk, failed as well.I was having issues opening other files but i updated the video drivers on my Dell M6600.
I am having a problem with an assembly not showing the correct total mass of all of its components and sub-assemblies. The value is out by nearly 20%, over 3000kg!
I have narrowed the mass discrepancy down to a derived part of a sub-assembly. But this incorrect mass is only present when I navigate to the derived part's iproperites via the browser tree of the higher level assembly where I am having the mass problem. It is as though the top assembly got some of its mass property information from a previous point in time, i.e. possibly before the derived part's mass properties were updated, and now refuses to look at the current information.
By the way, I have opened up and checked the mass properties of each sub-assembly and the derived part; and when opened individually these show as correct. I have also tried 'Rebuild All' with no success.
Is it possible for mass properties in an assembly to become corrupted?
From the inventor file menu how to get an in correct recent files list? I get a list that i never worked on. When I carefully take a look, it shows a combination of couple files i worked on and a many files that my colleagues worked on.The tool tip shows it reading from c: empxxxx
I have a roll formed sheet metal part set to use a k factor of .5. The blank size should be (hand calculated) 7.924. Inventor is giving me 7.892. I made a new part with the exact same geometery as the first and set it to also use a .5 k factor, this one develops correctly to 7.924.
I checked all the dimensions multiple times. What am I missing here?
The ribbon layout has changed by itself so that it now displays smaller icons and I have to click on drop down arrows to access sub menus - I had it correct displaying the icons with the sub menus next to them but it seems to have changed.
I have worked through ALL the options available in the ribbons appearance etc. and this doesn't change them.

I am using the keyway generator to place a keyway in a hub and shaft, but the depth of the keyway (and the height of the associated key) is not right.
I am using an 18mm and a 20mm dia shaft, both of which should use a 6mm wide by 6mm high key according to the ISO standard. [URL]
But Inventor gives me a 6mm wide x 4mm high key and the keyways to fit; so if I use a standard 6mm high key in real life it won't fit. There doesn't seem to be any way to change to a custom key height.
Or is Inventor using a different set of standards? It's pretty good at matching standards in other places, for example the gear and fastener generators, so this seems strange to me.
I have a client that is having difficulty with Design View Representations. He has approximately 15 view representations, each having items in different states of visibility. The icons display the modes of visibility correctly, however, there are no objects visible in the graphics window at all. Additionally, the option, "Find in Window" is missing when right-clicking on visible objects. Only when he copies the View Representation over to a LOD, and then saves that back out to a VR, do the graphics in the window appear correctly. Then the Option, Find in Window shows up and is available.
I have an assembly file in which I have created several levels of detail. My intent was to suppress specific parts in the assembly (for views in the idw and to calculate the weight of the assembly).
I have noticed that the mass is incorrect for the level of detail that I want calculated. I determined this after creating a new assembly and deleting all parts that were not used in this level of detail. And, by viewing all parts individually and adding them up by hand.
All parts in the assembly have the correct density. I have selected to calculate the mass properties of the active level of detail when updating.
My questions: Am I correct in assuming that the assembly will caculate only the parts that are not suppressed? Or, am I thinking of it wrong? Is this particular assembly messed up? I haven't noticed this before and am now concerned that my weights have been incorrect.
My solution to use right now is to create a new assembly just for figuring out the weight. I think there is a better way.
"The filename, directory name or volume label syntax is incorrect. The database in K;lah/blahlah.widget.ipt* could not be saved".It's nothing to do with an improper name; even saving as the default 'Part 3' doesn't work.
At the moment I'm limping by using Save Copy As. Neither Save not Save As work at all.
How to get surfaces in a dwg to display correctly in inventor 2012? (just upgraded after SP1) I keep getting random results. I have a seat from our supplier translated from solid works brought in as a composite (converted in inventor 2011). I have assigned colors to faces and in the part/assembly environment it is fine, as soon as it is in a DWG it goes randomly transparent! Some times it is completely see through and others you get an odd face displaying correctly! Even in different views on the same sheet different faces appear normal.
Attached jpegs are: surfaces in dwg and surfaces in an assembly.

After you create a drawing view, surfaces can be included or excluded from drawing views. Files that contain only surfaces automatically include the surfaces in a drawing view. Is there a way to disable this functionality?
