As part of the automation requirements we are working on (through the .NET interface), we would like to find out whether a given drawing contains a sphere and if it does we would like to know its properties. We are doing something like this, to loop through the database and am able to get all Solid3d type of objects.
What I would like to know, if a given solid3d object is a sphere or otherwise. The code snippet is pasted here for reference:
bool bContainsSphere = false;
foreach (ObjectId Id in Ids)
{
DBObject oObject = ts.GetObject(Id, OpenMode.ForRead);
if (oObject.GetType().Name == "Solid3d")
I am working on the AutoCAD customization and doing the same by VB.Net & C#.Net. But I just want to know the difference as mentioned below:
1. Insert Block In AutoCAD
Using VB.Net without using DataBase services..Only 1 statement is required to Insert the Block objAcadDocument.ModelSpace.InsertBlock(Required Arguments are here) Using C#.Net with DataBase services
There are many statments are there to insert only 1 block..Like Start Transaction, Lock the document, Get the Object Id Block etc...So my quetion is that when I have to use DataBase services and when not
what is the advantage of doing customization using DataBase services rather than go for wihout DataBase services.?
I am using Autocad 2010. I need to draw curved lines on the surface of a sphere, but how to achieve this? I need to sweep a profile across the surface of the sphere.
I have a sphere which I'm able to project on a sketch of smaller circles which I'd like to engrave over it's surface, yet I want each of them to be perpendicular to the surface of the sphere in each point. Emboss doesn't do the trick, it just makes the engraving perpendicular to the plane.
Any step by step procedure, to create semi-sphere in Inventor or how to draw semi-sphere ?I am unable get this semi-sphere, using all the "extrude", split" options.
I've been attempting to create a sphere with an Earth texture, for which I've made a custom appearance with a flattened picture of earth. Instead of wrapping to the sphere, however, the image is mirrored on both sides of the sphere and extremely distorted. I knew wrapping 2D geometry to a sphere was not strictly possible, but is there no way to pull it off with an image?
If not, would something like this be possible in 3DS max?
I have a sphere body whose material is partly removed by a boolen subtraction with another sphere. When I query the EdgeLoop of sphere for Outer edge loop using function InvEdgeLoopPtr::GetIsOuterEdgeLoop(), I always get a value of VARIANT_TRUE. check for the inner and outer loop of a sphere? use the attached file for reference.
I have a funnel with a curved top. I'm trying to project an inset of the border onto the curved surface and use the shell command to create a hollow funnel with an overhanging lip. I have projected the inset successfully, but cannot select the resulting smaller face, just the whole original face.
A similar problem that I tried while attempting to figure this out was shelling a sphere. 2d sketch -> 3d sketch project onto surface, and try applying shell to the resulting "face". However I can only select the whole face when trying to shell.
i'm a Autocad 3D newbie! Have some problems to figure out how to trim a solid from a sphere. well here's an image that will explain better!( it's the pink part from the green)
I'm picking this catagory as I think it is something that has been done before with mapping flat images to a 3D sphere (globe).
The application: Mapping a pattern design onto a sphere - in this case a marble. The pattern design is in pdf format and has been manipulated so that the image fits a certain sized sphere (2") around the circumference. I'm hoping to take this 2D image and wrap around the middle of the marble in full image length and have the image diminish as it rises to the top and bottom of the marble for fitting the surface.
I have lightly researched bring in a pdf format file into AutoCad and see that it can be done. Now I need to address the technique of wrapping it around a 3D sphere.
I am trying to create a spheric container with a irregular pattern of different triangle as show in the example attached.
What would be the best way to creat this part? i was thinking of creating each triangle in a different .ipt and after assemble them all toghter. But this will take ages and a lot of ipt.
I am modelling on an object which exists of a sphere with a lot of lightbulbs around it. I made asphere and 1 light surrounded by 6 lightbulbs. My intension is to make a perfect symmitrical sphere of lightbulbs.
I work with Autocad Mechanical 2012 (not for so long) and quit new into the world of CAD. I worked with the command array, and that worked fine, but I don't know how to repeat the cluster of 7 bulbs all over the sphere.
Imagine 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).
I'm looking to use Inventor Studio to render a model, using an image sphere (e.g. Stuttgart Courtyard) as the background.
I cannot find the installed location for these images, so even if it is the active view, Inventor will not allow me to render it, and I cannot manually select the file as my image sphere.
Also, are additional such image spheres available for download?
I need a path on a sphere like on the image I attached (sphere_spiral) for the result similar to image called "gomb". The only problem, metric spiral or coil / 3d helical curve path won't work because it doesn't end the result I need, because the lines are converging each other. So, I figured out I need a logarithmic spiral 2D sketch or maybe a sinusoidal path.
I need a path from the sphere's top center point to the bottom center point, projected to its surface with equal distance of lines.
Here is a still from what will be a trade show video. The problem is that the longitudinal lines are a bit wobbly, especially near the poles, for instance in the top right quadrant, between the orange and yellow earplugs. [URL]..........
I created a new 3D object with the preset sphere from a layer that is a grid of my client's products. As the sphere rotates, the black edges of the grid straighten out as they come around to the front, and then get wobbly again as they approach the edge of the sphere. At first, I made the black part of the grid from a bitmap mask (which had caused a problem in an earlier 3D file) but no, same problem when I made the grid from a vector mask.
Pretty sure it is not a hardware issue as I have gone thru all the optimization steps for using the Mercury Graphics Engine on my quad-core iMac 27" with a supported video card, and the latest version of OSX.
I'm trying to make a marble ball that looks wet, thus a reflection. I can pretty much get the ball (albeit not extremely realistic) and some what of a reflection idea going on after looking at some reflection tuts, but the reflection just doesn't seem to wrap right or something, it just seems...unnatural.
Is it possible to make the above in PS, then possible animate via IR to spin on on axis, also how hard would it be to put rings around the sphere (like Jupiter(?)
I believe I found this in CS2, but now I can not find it in CS3. Wasn't there a sphere tool that allowed you to wrap a bitmap image on a spherical or cylindrical curve, like a soda can or sports helmet?
We no longer have Reactor Softbody, so if I wanted a sphere to be dropped on to a table how do I get it to squash and deform as it hits the table (other than doing it manually with a FFD etc)
MassFX would do the basics of that but I can't see how it could deform the mesh?
What is the proper way to apply the symmetry modifier to a sphere ? I created this custom android bot. After I create a sphere with hemisphere I create the eye and split the sphere in two then zero it out on the grid. Then I apply the modifier. When I do that it does not project the other half of the sphere even when it's on flip and x axis. The mirror part is kind of on the back side of the sphere. What happens is I have to rotate the mirror part to line it up and up the thresh hold a lot to get the back side to connect.
