2d 2 3d 2007

thought i would keep it simple above and keep it numerical :unsure:

 

I am working with autoCAD 2007 and want to convert a 2D drawing

to 3D.

 

this is my first time even entering the 3D workspace so if I could

get kiddy step advice it would be great :cry:

Well for starters you have the following commands....

 

Extrude, PressPull, Sweep, Revolve and Loft to create 3D objects from your 2D geometry. All of these commands can be found on your Modeling toolbar as well as the Dashboard.

 

On the same toolbar you'll find your "Primitives" like Box, Sphere, Wedge, Cone, Cylinder, Torus and Pyramid as well as your Polysolid, Helix and Planar Surface commands.

 

Rounding things out will be the Union, Subtract and Intersect commands along with 3DMove, 3DRotate and 3DAlign.

 

A fairly robust toolbar comprised of the commands you'll need most in construction your 3D model. Next up: the Solid Editing commands.

 

One quick question. Are you at all familiar with orienting the UCS? It can be done manually or via the Dynamic UCS.

 

Last thing. Make sure to switch over to a 3D Modeling workspace and set it up with the toolbars, etc. you will most want to use then save this workspace under a new name.

2007 Toolbars.JPG

Should you prefer toolbars over the Dashboard these are some I would recommend when doing 3D modeling. I found that the Dashboard just got in my way so I ended up closing it.

 

Oops, forgot one. It is the View toolbar.

Surface&Solid.jpg

AutoCAD can create both Surfaces and Solids.

In the example above a 2x2 square (magenta) comprised of four lines has all four sides extruded (Extrude command). The result (middle) is four separate surfaces. The cube on the right, derived from the same four lines, was created using the PressPull command. The result is a solid.

 

Note: Visual style = 2Dwireframe.

guys thanks for the replies - much appreciated.

 

ReMark - BIG thanks for taking the time to post images/samples, those

toolbars look familiar, I did set them up last night. Not familiar with the UCS

to answer your question.

 

JD Mather - i'll check this out tonight - thanks

 

Thanks also for the links - i'll surf on those tonight :geek:

2007-3Dobjects.jpg

Some 3D objects created in AutoCAD 2007.

 

The sphere on the far left is a primitive.

 

Next to it is an arc that was swept along the path of a second arc (Sweep command).

 

To the right of that is a portion of a drinking cup created with the Revolve command.

 

On the far right is an object created with various diameter circles using the Loft command.

ok thanks for all the help so far.

 

i have watched a number of tutorials and they are helpful.

 

after tricking around with my basic 2D drawing in the 3D work space

and using the extrude command I can get a 3D image, but somehow

it doesnt feel just right.

Looks like you have extruded surfaces rather than solids.

Did you PE J the boundaries?

Try using the command Presspull rather than extrude.

ok erm presspull has been pulled into service - thanks . . .

I just cannot configure the 2 outer most holes.

I'll keep tricking - tomorrow

 

Thanks JD Mather:)

Are those two outermost holes counter bored?

 

I noticed that previously you ran into the same problem most newbies to 3D do when you extruded lines and arcs only to end up with surfaces. That's why I mentioned the PressPull command. But JDM got you onto the right path so all's well that ends well.

Counterbore1.jpg

Visual style: 2Dwireframe

 

Let's assume you want to counterbore the hole. To do so your geometry must be correct. See object 2 above? The smaller diameter hole passes entirely through the base while the larger diameter hole does not. My suggestion would be that you union the two extruded holes (object 3) then subtract both from the unioned base (object 4). Object 5 is a cutaway proving we have accomplished our task.

One method for creating a countersunk hole.

 

Watch out. JDM will try to talk you into buying a modern MCAD program like Inventor where all this will be much easier. Hold on to your wallet!:lol:
