AutoCAD Inventor :: Calculation On Length Of Folding Feature
Nov 19, 2011
I would like to know what calculation on the length of a folding feature is performed by Inventor when one folds it. Read my example to better understand my question.
I am trying to fold a part of my sheet 90 degrees, I am going to call the folding part sheet B and the rest of the sheet, sheet A. Now, understand that when I fold sheet B 90 degrees, its face will no longer be parallel to sheet A, but the face of its thickness will. Consider this, now: when I fold the sheet B, there will be an inner part of the folding (which will have the faces of both sheet sections 90 degrees from each other) and the outer part (which will have an angle of 270 degrees between them).
I want the distance between the thickness face and the outer face of sheet A to be X in length. Which is the intial length of sheet B for this to happen? Consider using the BendRadius, Thickness, and other Inventor Sheet Metal parameters that will participate in the equation.
The question surged because I wanted such distance to be 5 in a part with a Thickness setting of 0.5 (as well as BendRadius), but because of this folding length calculation, I had to make sheet B 5.631 in length.
We have many old sheet metal parts that are designed in Autocad environment and of course they are in 2D .dwg format. Sometimes it's necessary to get those parts in Inventor and "convert" them to 3D, but sometimes Inventor's "Fold" function isn't working like it suppose to work.
So all I'm trying to do is that first I'll import the flat pattern .dwg file to sketch,
then define the thickness of a part and lastly trying to bend the part with "Fold" function. Sounds easy, but it isn't always.
Especially sometimes Inventor wants to fold whole flange although there is a relief cut drawn. There is a one example in attachment when it happens. So is it possible to define the folding distance like in "Flange" function?
I've created a sheet metal part and have set my parameters. In using the fold feature, cannot create bend past 180 degrees. Radius is large enough (21") and sheet is long enough as there is still flat sheet after a 180 degree bend. How do you create bends past 180 degrees?
I want to bend/fold this piece over a specific profile. There are too many tools for bending a sheet metal and I just don´t know where to start. I searched the web and this forum but there are too many options. Also when I create the flat pattern, it should be precise with a difference max +/-5mm. I thought I could use contour flange. Usualy it works. But only when it´s a simple rectangle. But not on this part.
I am investigating best practice workflows for a feature length project shot on 2 Red Epic cameras and editing was done in Final Cut. I need to grade and finish the movie along with many other finishing requests like screen replacements, set clean up involving tracking and many other common DI requests and fixes. I use Resolve for most Grading but since there are so many FX shots that need work I was contemplating keeping everything in Smoke so I can make adjustments to the grade and FX in context of the whole edit.
Is this advisable for a 90 + min edit with Red footage? It might be doable but is it feasible meaning would performance be very sluggish? I have a 2009 Mac Pro, 24 GB RAM, 8TB RAID, RedRocket and Quadro 4000 card.
Would I be best off having the editor break the movie up into 10 - 12 minute sequences and then import each XML as its own sequence into one Smoke project?
If I import the Red footage at half res, because of performance, I am only using half of the info in the file. I have a RedRocket so should I import full res 4K to get maximum quality? Then let Smoke do a resize to 2K which is the final deliverable format? I figured that might be best for doing resizes and for sharpness.
If I work with proxies would all of my tracking and paint work be valid when I switch back to the 4K version for final render?
I'm creating a DVD with just one MPEG2 feature length movie. I've selected the movie and done all the technical burn settings.
What I want is for the DVD to begin with a screen that has the options to 'Play Movie' which plays the whole thing or 'Chapters' which then goes to a chapters menu. Obviously they have to be able to get back to the option to play the whole movie.
I've separated the movie into the chapters by doing Add/Edit Chapter and clicked Next.
Am I right that Add Title Menu creates the first screen, and the Add Chapters Menu then creates the Chapters Menu? How do you have the Play Movie option - or is that just achieved by playing the first chapter (ie does it carry on with the whole movie?) With each chapter, does it proceed to play the whole of the rest of the movie after that chapter?
Also, the first chapter has a black screen thumbnail. How can I change the look (but not the actual starting point) of that chapter?
What does 'close the disc' mean? Does closing it give better copyright protection on the movie being taken off the DVD?
Finally, how do I save all these chapters and settings so I can just a burn the DVD quickly next time without creating chapters etc? (I am creating a Disk file, but can I save it as a Project?).
My company recently installed Inventor 2013. In previous versions we used a part with negative density similar to seawater to calculate submerged weight and CoG.
In IV 2013, it seems that the ability to calculate negative mass is not longer available.
This is how it worked in pre 2013 IV, when I could specify a negative density.
What I have is a spool made of steel. This spool is modelled as an iAssembly with four configurations:
-In air, empty
-In air, filled with glycol
-Submerged, empty
-Submerged, filled with Glycol
For this example, I now need three parts:
-Steel Pipe
-Glycol derived from the inside volume the pipe
-Seawater buoyancy derived from the outside volume of the pipe.
Each part has its own density, and the assembly weight and CoG correspond to the assembly configuration (with or without glycol) and environment (in air or submerged).
The seawater buoyancy represents the water displaced by the total spool assembly, regardless of the contents. To achieve correct weight in the submerged state, the buoyancy material has to have a negative density.
I do not want to make any of the mass parameters static, and I also fear that the CoG might not be updated correctly when using that method.
As I no longer can define a negative density, any optional method to achieve this without overriding the mass value.
I am trying to calculate the area of our parts. I was trying to do the math my self but I kept getting a lower area than IV. I haver attached a picture of what I get from IV. I have listed my calculations of the angle iron below:

I've has Inventor tell me this for thin walled tubes with holes in them, but not for a simple part like the attached one. Autodesk are you listening yet? This has been an issue for a long time. Mass calculations for parts with holes on curves do not work properly. On many parts the error comes up with "low" selected. By default each time I try to save the file, the error window pops up.
I have a problem acessing the fatigue calculation panel in the bolt connections´ tool. Whether I press enable or disable I simply can´t acess it. What should I do to access it?
I am working on a Sliding Folding Door simulation and I am having much difficulty applying limitation to angular dimension and applying constraint to blocks (sometimes it works, sometimes not).
I want to know whether there are ways to set variable angles i.e angle x instead of a definite angle i.e angle 75.
Is it possible to change the length of a line based on the length of an attribute?
I'd like to make the line a MINIMUM length of X" (I haven't decided how long yet--but know I'll need a minimum). But then after the user fills in the attribute, I'd like the length of the line to change to the length of the attribute plus a small amount (again, I haven't decided yet how much extra).
I was wondering if there is a way with DB's to have a line "follow" or "grow" with the content/value length of an attribute. Maybe some method of linking the attribute width to length of the line? Essentially, it would work just like turning on the underline setting when typing in mtext editor (or any program with an underline option for that matter), expect that the line could be placed anywhere, and would not have to reside directly below the text.
With using superelevation wizard in Civil 3d 2012, changing the lane width is not affecting the resulted values of transion length and run-off length, Is that correct ? ( as civil is using standerd AASHTO tables which assume that lane width typically is 3.6m )
Also, There is only 2 tables for 2-lanes and 4-lanes roadway, Is it for total road width or for one directon only, and what about different no. of lanes ?
I am creating a block with attributes for a standard job. I have (4) total attributes in this block (for example: panel type, qty, length in imperial, length in mertic)
I would like my length in metric attribute to automatically populate based on the input from length in imperial.
we are doing a customization of part in inventor , where we have done fork plate with constraints in model and extruding it with inputs from excel sheet. the plate size is getting changed as per the input given excel sheet.
but during the 2d drawing generation, if i take bom - the length and width columns are not coming.
I don't know if this is common knowledge when editing 3D, but you can creates scaffolding to allow you to move the CCS more easily and place parts where you want. So the easiest way to get your parts placed correctly is with a little scaffolding.
Scaffolding is just a 3D part you create, with specific known dimensions, so that is exists in the model-space and either intersects it at different locations, or provides an external reference point to move the CCS origin to.
Here's an example. Suppose I want a 20mm long, 10mm diameter cylinder, with a 5mm hole all the way through the side, with it's center about 5mm down from the top.
Creating a temporary scaffold to locate the CCS origin is the only way to do it without having to use tools like MOVE and ALIGN, and may be necessary even to use ALIGN properly.
I'm making a tube that is connected on another tube. I did this by skeleton modeling, for my tube extrusion i used Extrude To surface.
Is there any way to get the length of that extrude?
I know its possible to get the sweep length like this. Is there a way to get the extrude length as well?
'Set a reference to the active part document
Dim oDoc As PartDocument oDoc = ThisApplication.ActiveDocument Dim oDef As PartComponentDefinition oDef = oDoc.ComponentDefinition Dim opath As Path opath = oDef.Features.SweepFeatures.Item("TheSweep").Path Dim TotalLength As Double TotalLength = 0
As I wrote in "Applying inverse kinematics to a folding rule" I succeeded with the first step.
Now I would like to make it behave like a whip. How to accomplish a whipping animation?
I did some motion capture of a person whipping an imaginary whip, so basically the folding rule just has to follow the hand and behave the way a whip would within the folding rule's constraints. How could I do that?
I am trying to dimension a line that is not parallel to either they x or y axis. When i try to dimension the line it will only let me dimension the vertical or horizontal component and not the diagonal length. I have included a picture of what I am referring to.
I have a problem with file path length BOM. I need to show in BOM only the last folder name, not the whole length of file location. At the moment i´m doing it manually and it takes lot of time to look and find each file location.
The bug giving incorrect lenths of frames created on internal cutouts with fillets using merge hasnt been fixed in 2011 SP2 (64bit). Base part attached for testing.
I just missing something or is there no way to get frame generator parts to list their lengths in feet?
I have authored some structurial parts and everything was done in feet, when I insert them directly from the Content Center, everything work like I want it to, but when I use frame generator they lengths are always in inches.
I know I can change it in the BOM but I'm trying to make it more consistant for everybody.
