AutoCAD Inventor :: Determine Moment Of Inertia Of L-section - 2009
Jul 22, 2010I am trying to determine the moment of inertia of an L-section using IV 2009. By selecting Tools>Region Properties of a closed loop profile in the sketch environment the moment of inertia is given, however the principal axes through the centroid are at 45 degrees to the toe of the angle (see attached image). I want Ixx and Iyy where the X and Y axes are parallel to the horizontal and vertical toe respectively.
Coincidentally, AutoCAD orientates the principal axes the same when viewing the Region Mass Properties of a similar Region.

Jul 10, 2012How the mass moment of inertia (kgcm2) is calculated in inventor?
It says it is calculated using negative integral, however i dont find this very informative.
I used the data for a report, and need to justify how i got the center of gravity and inertia properties.
A formula, method or algorithm would be nice.
AutoCAD Inventor :: Area Moment Of Inertia Round Off Error
Oct 15, 2012I have a problem with Inventor pro 2013 rounding of the area moment of inertia to zero (region properties). For example if I create a new sketch and draw a 1 mm x 0.5 mm rectangle and measure the area moment of inertia it will be 0 for one of the pricipal axes. If I change the rectangle to 1 mm x 0.6 mm it doesn't round it off. Seems like there's a problem with the precision in the calculations somehow.
I have tried to change the document units to microns but the same thing happens.
is there a way to make inventor do this calculation correctly?

Sep 5, 2013I have two sections both region-ed. What is the correct way to find the combined inertia. The sections kind of "fit" into each other. So far I have used two different methods and I don't know which is correct.
1. Centre each section individually, find the section properties of each sections and then add them together.
2. Combine the section, centre them together, and then find the inertia of the combined sections.
So which one is correct? The first one gives a much smaller I value then the second ones.
AutoCAD LT :: Changed To Layout Tab For A Moment And Then Back To Model
Sep 19, 2012I ran into a problem with my dimensions. Everything worked just fine until suddenly, in model tab, every new dimension i wanted to draw, looked like this (see .jpg attatchment). I didnt modify anything. Just changed to layout tab for a moment and then back to model. When i changed the text height into 10x bigger just to see the difference, the white dimension line just got wider and thats it.

May 8, 2012I'd like to know how inventor defines the center of rotation when you apply moment load on multiple faces at once. I'm not basically able to define where exactly I need that axis to be. and I dont understand where inventor assumes that axis is. if you take a look at attached model, obviously the resultant forces caused by the applied moment are bigger on the single pillar located on the extention, thats why its been displaced more than the others, but where exactly is center of rotation. I'm trying to avoid modeling of the section above this which technically transfers the moment thorough shear pins on the structure I have modeled.

3ds Max :: Move Tool Moves Objects With Inertia?
Nov 19, 2013Try to move an object and it does not stay fixed to the move tool cursor, but instead it accelerates off in the direction I initially tried to move it..... but in a sliding inertia type multiplied movement. Have I selected a different mode for the move tool by mistake?
I've checked the pivot point of the object I was trying to move and it was located centrally, nothing strange there.
Also, after the object has wizzed off the screen, pressing undo or [ctrl+z] won't bring it back to it's original location. The undo option is greyed out in the edit menu, suggesting that nothing has been saved in maxs undo history.

Photoshop :: CS5 With OpenGL - Disable Inertia When Moving Window?
Apr 21, 2013Following a hardware change, photoshop automatically re-enabled a feature I had deactivated, the OpenGL acceleration.
I gave up on it 18 months ago because of one thing that incredibly irritated me, the crazy "inertia" when we moved elements.
Let's say you have an open document. The image is too large for your photoshop window, you only see a part of it.
So, you keep the Space key held, and you drag and drop with your left mouse click.
Without openGL acceleration : the moving ends as soon as you release your mouse.
With openGL acceleration : the moving gradually slows down until it comes to an end, meaning you have zero control over your work window.
And, well, that's enough of a bother for me to give up on OpenGL acceleration.
Any way to get rid of this feature ? I searched everywhere I could, I think I tried every one of photoshop's options, but to no avail.

Apr 25, 2013I am having a problem where Photoshop does not always give me accurate color display all the time. I am aware of the situation but this has become an issue where I have to edit some photos for a pro lab output. The monitor has been calibrated and delta E is less than 0.5, which is okay.
Attached is the print screen of PS at one moment, vs the print screen of PS at another moment (they were layered and mask applied). Dragging the image U/D/L/R also shows the colour one or another. This becomes quite an issue since I had no way of telling whether I am seeing the correct color, especially when I am soft proofing or converting color profiles for final output.

AutoCad 3D :: Place Sphere On Top Of Hollow Cylinder?
Oct 11, 2012Imagine a basketball sitting on top of a pipe that is half the basketball's diameter: as a result, an inverted dome is comprised within the pipe. The intersection between the cylinder and the pipe is a circle.
How do I place a Cylinder on a Sphere?
I want to be able to move the cylinder and take a point from the sphere where I can attach it(the cylinder).
I will use the sphere as a joint for multiple cylinders so the intersection between a sphere and any cylinder must always be the circle that forms the base of the cylinder NOT another circle parallel to the base(if the cylinder enters the sphere, if you place a metal rod through a snow ball, the resulting object is a bullet, a cylinder with a dome: not what I want).

Nov 16, 2012I have turbine rotor blade designed as per the aerodynamic considerations. The profile i obtained from the company is completely solid, I would like to make it hollow with a wall thickess of 5 mm. I tried if with the Shell feature of Inventor, and Since the profile of the blade is in different planes twisted in different angles, the Shell is not working very well. I have tried it with loft with different cross sections, but i am not getting a completely accurate profile. Is there any tool which automatically recognises the outside profile and will make the Inside hollow also in Inventor?

Oct 31, 2012I do a lot of CNC milling of molds for foundries. Lately I get a lot of models that need cores and they are made without regard to the inside dimensions.

Any easier method of creating the solid core. Attached is a simple model of a simple part. How would the inside hollow area be created as a solid?

Lightroom :: 5 - Moving Develop Module Sliders Blurs Image For Moment?
Aug 5, 2013I'm evaluating Lightroom 5 during the 30 day trial and it's all cool except for this one big annoyance that I noticed immediately when trying to work on an image in Develop module. As stated in the title, moving any slider (exposure, highlights, noise reduction, etc.) causes the image to go very blurry for the duration of the slider movement. It goes immediately back to being sharp as soon as I stop moving the slider. This is super annoying, feels as though my eyes are going bad.
What's interesting is that the problem doesn't show up when I'm adjusting the Tone Curve directly, but it will get triggered if I'll expand and use the sliders underneath. So looks like a bug that only applies to sliders.
This doesn't happen at all in Lightroom 4.4, which I still have installed and can compare side-by-side.
As for the hardware, I'm using the 2013 Macbook Air with 1.3 GHz i5 CPU and 8 GB of RAM. The OS X version is 10.8.4 with all latest upgrades installed.
I've already tried optimizing the catalog, giving it more space (currently at 3 GB) and purging it. I'm not using Smart Previews, although I've turned them on for a moment to see if the problem persists with them on - it does. I've also re-rendered the 1:1 preview for the specific image I've been trying it on. Btw, the file is a NEF from Nikon D300 and I'm using the 2012 process (as was the case with LR4). Not sure what else might be relevant here.
AutoCAD 2013 :: Section (plan / Elevation / Section) Snapping To Point Cloud

[URL]........
I just want to create a section from the point cloud, but the point cloud won't allow me to select it as an object in the 'Generate 2D/3D section' dialogue as it's not a solid/surface.
On an unrelated note, I find snapping to the point cloud impossible - is there an option in OSNAP that I'm missing? I've tried this with attached PCGs and RCP point clouds, no difference.
