If I enter the Stress Analysis Environment in 2012, I can apply pressures to surfaces, but what if the pressure varies (eg, with height as it does in a tank holding a fluid). Is it possible to apply a variable pressure to a surface with Inventor's FEA? It doesn't seem like it, I also searched this forum and the net, couldn't find anything. Usually one can enter an equation, that also doesn't work.

My pressure tablet doesn't apply pressure using the pencil tool -- or any other tool-- It's a CTH470 Bamboo.
View 5 Replies View RelatedI am trying to create a pressure pipe network (right now I have 2 pipes) and have it follow a surface. When I click to follow surface it lowers the vertices but does not add any additional vertices to make the entire pipe network 5' below surface. My pipe lengths are set to 18' and the surface I want to use is set in my network properties.
View 4 Replies View RelatedSo, I really like the ability to have a pressure network pipe follow a surface but, what if I no longer want the pipe to follow the surface? Is there any way I can get rid of all the extra grips that are added to the pipe in the profile? The only way thing I've come up with is to delete the pipe and recreate it.
View 1 Replies View RelatedI am doing some car park designs with Corridors at the moment.
The method I am using is to create a dummy surface and apply surface profiles to all Baselines and Targets (mostly Offset Alignments). This way if I have to change my levels, I simply amend my dummy surface and everything updates straight away.
This works great, but I recently got a (typically random) Fatal Error. I recovered the Recover drawing which was saved and for some reason all profiles changed to Static and I can't change them back to Dynamic.
I know that if an alignment cant find the surface it will change to Static and I assume that during the fatal error or recover process, something must have triggered for this to happen?
Is there any way (other than resampling all profiles and updating each corridor target individually) of making the profiles dynamic again?

I have just purchased a Microsoft Surface Pro in anticipation of running Photoshop on it. I installed Photoshop and tried to do some sketches. I created a new file and started sketching. I Immediately felt like something was wrong. I checked my brush settings and saw the pressure sensitivity was not available. Everytine I tried to turn it on it was marked with an exclamation point.
Does Adobe is supporting the new pressure sensitive pen from microsoft, or if there is some sort of setting that I am missing? I have tried sketchbook pro 2011, and that works amazingly well with the pen.

For example, I would like to put grass on a whole plane directly, without having to use the brush to paint the object.
I have a lofted surface and would like to make a difference with another surface.
This doesn't work (Difference returns absolutely the same 2 objects instead of Object1 - Object2).
In the attached example, I would like to have a square "window" in the "wagon" shape.How can I do it ?
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.
It is not possible forme to add the fil because it is to large 1.8MB how can I poste then I like to know if it is possible to extend the button flat surface diameter ø12.5 up to the shaped surface. The result should be a total solid block whit a surface shaped hole.

View 9 Replies View RelatedI have a question regarding simulations in Autodesk Inventor.
For example I have such part:
It is a plug made out of brass. I want to test if it will be able to withstand specified pressure. So I set up where is it constrained - on thread.
And set up pressure from inside on the cap to be 16 bar (1,6 MPa). And also assign materials. And there goes simulation . Everything seems alright. I want to run little bit different analysis. When pressure would be variable.
For example I will have pressure going from 12 bar to 16 bar, and such simulation will be running for quiet long time (as an example pressure will be 12 then raises to 16 then goes to 12 again and then raises to 16 again). I want to know after what time will this plug fail and will be destroyed? I mean i want to know when METAL will get tired and will be destroyed? I was just wondering if such a simulation is possible to be made in Autodesk Inventor?
I'm an Inventor 2011 user and I'm writing a Ilogic script to update an assembly. For this I want to use a variable in a name.
For example d1 till d10 will be given the value 25.

n=1
for n<11
dn=25
n=n+1

I have found a rouind about way to display document thumbnails in VBA in 64 bit windows 7 inventor.
The only piece of the puzzle I am missing is for a way to push a document object or a document file name into an iLogic Rule from VBA.
Below is a 64 bit thumbnail solution for VBA sans the input.
Essentially I am launching an iLogic Rule from VBA that pushes an inventor document object into a VB.NET dll.
The dll converts the iPictureDisp into a VB.NET image object, reduces the size then converts it into a byte array.
The byte array is passed back to VBA through the same iLogic Rule.
Once the byte array is received it is converted back into an iPictureDisp object.

View 2 Replies View RelatedI made a custom model rocket a few days ago and I posted some pics online. A lot of the rocketry community gave me crap that my fins are too small, and my nose cone was not the right shape.
I made a CAD of the rocket in inventor and I would like to run a simulation so I can see what it will look like when the air is flowing over my rocket.
Here's a STEP file of the rocket, as of now I don't have the density of the parts set because I am still trying to figure out how to add custom densities. I know that there are somethings about the rocket that don't seem right, like the nose cone that doesn't go over the sides of the tube - but that was a machining error on the actual rocket and I wanted to make the CAD as similar as possible.
When adding pressure loads to a perpendicular face inventor states that the pressure is applied uniformly to the selected face.As an example a disc of 300 mm dia(area= 70685 sq mm) with a uniform pressure load of 10MPa.
Is the 10MPa load input construed by inventor as 10MPa per square mm or 10MPa over the entire disc area.which is the correct interpretation?

I have an iLogic rule in which I'm trying to set three user parameters for the gage of each leg of a steel angle. I want Inventor to set the gage based on the length of each leg. Here's the table I referenced for gages: [URL].
In my code, I have a sub called DetermineGage which takes the leg length, whether it's the short leg or the long leg, and determines the gages that should belong to that leg. Inside of that sub it calls on a sub called ApplyGage which then applies the determined gage to the rule's gage variables. The main sub then grabs those variables and applies those values to the actual user parameters.... In theory.
The rule executes ok with no errors, but doesn't change the value of the user parameters; they're always "0". As best I can tell, the "oGage" variables I used in the rule don't even get assigned the correct value, which makes me think the DetermineGage and ApplyGage subs can't even access the oLegLength or oGage parameters to read or set them. I don't want to use global parameters because I've heard that can make programs very unstable over time and is just bad practice. How can I make these variables accessible to all subs IN THIS RULE, no more no less?
Sub Main()Dim oLegShort As Double = Min(G_W,G_H)Dim oLegLong As Double = Max(G_W,G_H)Dim oLegLength As DoubleDim oGage As DoubleDim oGage1 As DoubleDim oGage2 As Double'Short Leg:oLegLength = oLegShort'Call DetermineGages sub to set oGage variables:DetermineGages()On Error Resume Next'If gage parameter does not equal true gage, set it equal:If Parameter("ShortLegGage") <> oGage ThenParameter("ShortLegGage") = oGageEnd If'Assume error means gage parameter does not exits.

I want to create numerous custom properties for a part. Some of these will be the same for all instances of the part (i.e. vendor, part number, etc). But some have to vary from instance to instance.
So, as an example - if I place 5 identical tanks into my assembly I need to assign unique text entries for each of these 5 instances (i.e. TANK-01, TANK-02, TANK-03, etc)
Furthermore, all these textual properties have to be able to be shown physically on the part (for identification on plots) and extractable for BOMs, etc. It seems that any custom i Properties I set up are global for all instances of the part.
You can create a variable pitch helix by using the Equation Curve feature introduced in Inventor 2013.
Create a new 3D Sketch. Start the Equation Curve command.
Here are equations that I use to create helical curves. Many other variations exist.
Cartesian coordinates:
x(t) = radius * sin(360 * num_turns * t)
y(t) = radius * cos(360 * num_turns * t)
z(t) = height * t

When you sweep a profile along a helical path, use the plane normal sweep (instead of perpendicular sweep) to orient profiles suitable for coil or spring. In the example below, the sweep path is a constant radius, variable pitch helix.
