AutoCad :: Calculate Forces The Object Can Withstand
Aug 7, 2012
I am designing wing ribs for a prototype, ribs made with fir wood; I must make cuts in the ribs in the form of circles or triangles to reduce the weight but keep the strength. I think I will use circles because a triangle's corners can be starting points for fissures(maybe triangles with rounded corners?).
Given: wood type,fiber alignment, rib dimensions, pattern of circles and circles' diameters, can Autocad calculate the forces that rib can withstand on each axis ox,oy,oz?
Is there another program that can tell me what forces an object can withstand given information about that object?
With command massprop I can get many interesting data about 3d object, but where can I set material that my object is made of. Lets say I need to calculate volume and mass of my object which is made of aluminium, what are my options?
I'm trying to run my cleanup script on a set of drawings just received from a consultant. Unfortunately every time a DWG is opened the purge fails with:
PURGE cannot be used on partially opened drawings.
Now to get the file opened NON-partially, I have to first open as partial and click the "Load All" button and "Yes" to bloodywell open it normally. Then the purge actually "works".
This needs to be done manually. Yet even after I've done this and then saved the DWG again, another normal open again gives the same error about Purge not allowed.
how to get the DWG to open non-partially when I'm running my SCR? I don't want to clean the 80+ drawings manually.
I am trying to properly stress test a steel aircraft fuselage. I can easily model the estimated weight of the pilot, copilot, etc as loads on the airframe. However, when it comes to simulating a high-G situation, (a load factor of around 7.5 times the force of gravity), I am not sure what to do. On one hand, I can simply multiply the loads on the airframe by the load factor and see if the frame can take it. In most cases, it performs very poorly, (safety factor less than 1). However, if I model all the loads under normal conditions, (normal pilot weight, etc.), then add a gravity load equal to 7.5 G, the airframe performs well. Yet I am not sure if the loads on the airframe, (such as pilot weight), are being adjusted along with the increased gravitational load.
My question is, what is the best way to accurately simulate real world loading for high-G situations?
If you can imagine a cylinder sliding on curve joint. Let’s say the curve is in the XY plane. In the output grapher it is possible to display the force as the cylinder slides around the curve. However if I understand it correctly the magnitude of the force will be in the direction perpendicular to the point of contact between the cylinder and the curve? In which case is it possible to actually find out the individual X and Y components of the force? That is to say the magnitude of the force in the X or Y plane of the curve?
I am using Inventor 2014 to do a simple stress analysis.
I am looking for the reaction forces at fixed boundaries, but I can't find how I can get them. Displacement, stresses, strains, everything works, but where are reaction forces?
I installed it and every time I try to make a picture use the 2012 item it forces me to use the old one. I have never seen such a useless go round the pole! Far as I see it does nothing. At least LR4 lets you use the thing. If this is what it does how do I uninstall?
My video clips play in sequence with thumbnails in full screen view, but freeze and shutdown software in slideshow mode. My goal is to burn slides and clips and show on TV via dvd player. Why does everything work fine in full screen mode and not in slideshow mode?
I am trying to set up auto importing by tethered shooting with a Canon 1Ds (but don't think brand and camera matter.)
I never use DNG, and am not aware of, and after a lot of searching, cannot find anywhere in the LR4.3 preferences at which I specified DNG conversion. In the Auto0Import dialog there is a File-handling tab that offers one choice: how to spell the dng suffix. The files I want to import will come in as CR2., and testing this with other folder destinations and with Canon's EOS Utility prove that the camera is "sending" CR2 files.
i created new polygon´s SDF (ACAD Civil,Map2011). And created new feature from geometry (from 2 closed plines - island). See on attached picture. If polygons are more complex =erroneous result from calculation ("Round ( Area2D ( Geometrie ), 0 ) "). It means ACAD calculate sum 2 areas together, but It should dedust island from main polygon.
calculate the volume.I attached here my dwg file. I never done this before and I want to know the correct answer when I want my land to be levelled at 6m.How much volume to fill and the land to be removed.
I'm using AutoCAD 2013 x64 and VS2012 Express with ObjectARX 2013. Now I want to calculate the (projected) intersection point of 2 (intersecting) lines in vb.net
After selecting the lines I have this line1.IntersectWith(line2, Intersect.OnBothOperands, intpts, 0, 0)
In Visual studio express 2012 I get the following warning for the above line of
warning BC40000: 'Public Sub IntersectWith(entityPointer As Autodesk.AutoCAD.DatabaseServices.Entity, intersectType As Autodesk.AutoCAD.DatabaseServices.Intersect, points As Autodesk.AutoCAD.Geometry.Point3dCollection, thisGraphicSystemMarker As Long, otherGraphicSystemMarker As Long)' is obsolete: 'Use the overload taking IntPtr instead.'.
So, if I'm reading this correctly, this method is outdated and I should use an other method to calculate the intersection. But I really don't know what 'Use the overload taking IntPtr instead' means.
One of the things I found is a function that contains this line of Dim inters As Point3d = line1.IntersectWith(line2)(0). This one looks almost the same, but doesn't give me the warning when I compile the code, but this method crashes AutoCAD when there is no intersection between the lines. This is despite a try catch block that surrounds the code.
For now I just want to use lines, but I need to expand the code so it will also work with circles, arcs and polylines.
There are points in different levels i wanna make the surfer with this points and project the surfer on the down surfer(that makes with other points) after that make an enclosed Volume and finally Calculate the Volume between this 2 surfer. How its possible to Calculate?
If I want to calculate the square mm of an area, how do I do so? I know this should be really simple but I can't get the results I want. Let's say I have a rectangle (2D) and I draw somew circles and polylines within it that are 'cut out' from the rectangle....how does one calcualte the remaining square mm?
How to calculate in AutoCAD the Conversion factor. I need to calculate the complete Building Floor and I try the field command in AutoCAD, But I don't know what I should write to conversion factor.
If I want to draw a 10% slope on 5' contours how do I calculate the circle diameter needed to construct the slope in order to connect the lines where the circles intersect the contour?
this is my first query how to calculate man hours per drawing. whether based on size(a1,a2,a3,a4) , or by based on drawing.. some companies they are calculating based on sheet size...
I am trying to calculate muck away for work, and I have drawn the site plan in millimetres for accuracy. However when I try to calculate the volume I get this value: 3.6293E+12. I am guessing that it is saying this due to the fact its in millimetres, and I am trying to calculate a large area and convert in into metres squared. What this value means?
I'm struggling with the maths needed to calculate the angle between 3 points. My eventual aim is to use vba to draw a crescent shape polyline, ie 2 arcs curving in the same direction and joiing at their tips. Both arcs will have different centrepoints but the same radius. The only info I know so far is radius (R), centrepoints (CP1, CP2) and the intersection points where their end points meet (IP1, IP2). I've gotten those points by using the 'IntersectWith' function on two circles.
My coding skills are fine it's just the maths I'm struggling with and after searching google for quite some time I'm still confused. I've looked at loads of differnet formulaes and diagrams, but it always seems like they aren't complete. Maybe it's just me.
How do you get the spacing you want for a hatch? For example if using ANSI 31if under pattern scale you have 1.0 what spacing does 1.0 represent? If you want your lines 1'-0" apart how to you know what scale to use other than trail and error?
What formula Civil3D uses to calculate the average slope of a surface?
The formula I am using is S = I*L/A
S = Average Slope I = Contour Invertval L = Length of Contours (ft) A = Area of parcel (sq. ft)
I just had to do four parcel calcs and the percentage I find using the formula is always 1-3% lower than the percentage Civil3D spits out. I can't find anything about how Civil3D arrives at that number, it just appears. I assume that Civil3D is more accurate but I can't give that number to a client without knowing how the program arrived there.
We do a lot of chutes (for mining). They need to be painted on the outside only. They also need to be lined with rubber sheet on the inside. The area given in the physical tab in iProperties is the total area.
The area of the edges of the plates are small enough that we can ignore them, but is there a way to calculate half the model's area and get that result in the drawing in a text note?
We've only recently switched over to Inventor (used to be on Solidworks, where we had the same problem).
I need to calculate square footage quickly. I am currently polylining everything. Here is what I need to do quicker:
Calculate square feet of each room with these requirements:
- When meeting a hallway to the outside face of the wall - when next to an adjoining space, to the midpoint of the wall - When against an outer wall, going to the face of the wall.
I have a cast aluminum part I need to calculate the surface area for our plating process. I have done a simple area, its not right (.015ft^2). I have derived it as a surface but can't get a volume calculation.
