AutoCad 3D :: Place Sphere On Top Of Hollow Cylinder?
Oct 11, 2012
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).

Place holes evenly around a hollow sphere other than the increasingly complicated way I've been trying to do it?

In inventor 2013 I want to extrude a horizontal circle on surface of a bigger vertical hollow cylinder. but what i did it enters into cylinder, and i only want to extrude it on external surface.

I am trying to get hollow letters in a solid box.
I used a font called swiss 721 blkouI bt which is hollow.
I made a solid red box.
The letters seem to go behind the box and not in it........ I know layering might be a factor, however I am now on my 2nd week of autocad......?

I have created the model in the picture in AutoCad, but I do not know how to create it in Inventor. In Inventor I Know how to extrude and draw 2d/3d sketches, but this simple model it is impossible to me.
It is a simple 3D part, no sheet metal or pipe. It is an structure. I have copied it sliced to make more clear the geometry that I am looking for create.

I 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?

I 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. Usually I explode them and break them down as far as I can then delete all but the inside surface then reloft the geometry as a solid. More and more models are coming with very intricate cores.
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?

I have a small section of hollow tube as an IV part which I need to cut to at one end to produce a tapered effect. Attached is a mark up of what I am trying to achieve with the hollow tube.

I have a solid bar which has a diameter equal to the nternal dimensions of a SHS. I am trying to create a weld, basically to fill the gap with a weld. I tried a similar arrangement with a Circular Hollow Section and it worked perfectly. I have tried fillet and groove for the SHS but it will not accept it.

I'm trying to create a model of a Golf club head. I need it to be hollow but I am unable to do this using the shell operation or by creating a surface and thickening the faces. I created the geometry by lofting a series of sketches. I think the nature of the geometry may be causing the problem.

FEA of a hollow metal ball.
The case is-
1. hollow steel metal ball OD 200mm, ID 190mm
2. Outside surrounding uniform pressure 10 MPa.
3. The ball is floating in a kind of liquid, so the gravity is neglected.
How to run FEA on this ball? How to add fixed constraints.

I am trying to create a tube by sweeping a circle along a spline. I read many of the previous discussion threads on the topic but I still have some issues.
I first created my spline and transformed it in a polyline (some people recommended to do it). Then I created the circle. Finally I sweep the circle along the path.
The issues are the following:
1) when I look at the tube using the 2D wireframe mode, I can see that the primitives are not completely regular. In some points there are weird intersections and I don't know how I can fix them.
2) I hoped the tube was solid. However, when I exported (as .IGS) it and see in another program, I realized that it has only two circular caps at the extremities of the tube, but inside it is hollow.
I tried to transform it in solid or mesh or whatever, but it always gives me an error, saying that the object cannot be converted.

So i draw a body (or assembly) and i would like to invert what i draw ( tubing for fluid flow) to be hollow and make the hollow part solid, is there any way that i could do that?

Currently I am using 2010 Map 3d, for water main base plans.
I use Micro Survey to process my field work. From there I open in Cad, import layers from our GIS data base for property, buildings, addresses, etc.
The only thing I have done different is from another project was copy and paste some utility layers.
Now my drawing turns any plines with width into hollow lines, and if align something my drawing will zoom to extents, also text mask does not work and i tried turning text to Mtext and it will not let me select yes for background mask.
All other drawings I check everything works fine.

I am trying to make a Dynamic block for Circular Hollow Sections. So i have a block properties table with 3 columns.
SIze (description) | Outer Diameter | Thickness
i can add a diameter constraint to the OD no problem but how can i add a thickness constraint? i cant pick say a linear or horiz between the quadrants of each circle it does not let you.
Now clearly i could convert all my tabular data to Inner Diameter instead of Thickness but i was looking to see if there is a way i can do it like described?
Also - i think i could also do this with an equation in Parameters Manager but for some reason that does not open, every time i click it the dialog does not display nor does it show anything at command line, i know this means its maybe corrupt but i can afford the time to reinstall just now.

I am using Photoshop cs6. I purchased a template for magazine advertising purposes. The images have been taken out but there are custom designed objects (masked shapes) where I am supposed to place my images. When I attempt to place a photo into one of the shapes, using the Place Command, it does not work.
How can I place an image into one of the objects?

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.

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")
[Code] ......

I saw a globe designed in half, turning around. You could see the interior with the continents visible on the in- and outside.
So it looks like a boll cut vertically in half and made hollow with the continent projected on the inside and outside.

I'm completely new to Photoshop and am having a lot of trouble just figuring out how to do simple things. It's been frustrating, to say the least.
All I want to do is make hollow text over a transparent background so I can place the text over any color and I'll have the hollow text show.
So if I have some text, I just want it to be hollow and have the center be whatever the color of the background is. Maybe this isn't as easy as I thought, but I know I can make the background layer transparent of a new project... if I add some text and make it hollow, won't it adapt to the background color?
