Simple 3D Question

[Chris_Dahler@adobeforums.com]

I'm new to Illustrator, so please be gentle! I'm trying to draw a simple cylinder. If I draw a square and then use 3D revolve (or if I draw a circle and then use Extrude and Bevel), I get a cylinder just fine. However, I'm just trying to get an outline of the cylinder, what you would get by applying Wireframe shading to the cylinder and then removing most of the wireframe lines down the sides, leaving only the lines which define the two curved ends of the cylinder and two straight lines connecting the ends together. I can sort of accomplish this just by drawing a square, curving out one end, and then plopping an ellipse over the other end, but to get that right the curve of the ellipse has to match the curve drawn on the other end, and that doesn't seem to be easy to do. Any quick help? Thanks.

You can simply copy the curve of the original to get the proper curve of the other end.

I start with an ellipse, drag/copy it down and then use smart guides to draw a rectangle that is snapped to the outer anchors and then I unite those two shapes and stack them under the original ellipse. Takes about 10 seconds.

Draw a rectangle, draw one elipse at top of cylinder, copy drag elipse to bottom, select all three, go to pathfinder pallet, click on the "add to shape" button (the first button on top row), then click the expand button. You now have a basic cylinder shape.

Another fun plug in is called Vertigo 3D Pop Art. You can apply all type of 3d extrusions to flat line art even text after it's created as outlines. Follow this web link <http://www.vertigo3d.com>

good luck!

To use the 3D effect for this, draw your rectangle and give it a fill and no stroke. Perform the Revolve 3D effect, and in the 3D dialog, specify No Shading in the Surface pop-up, and click OK. With the object selected, go to Object Expand Appearance. This will give you a front and a back of the cylinder. The front is two objects - the top of the cylinder and its length - which are just what you want. You can delete the grouped items in back.

Hi,

I am sure this is a simple question (or that the answer will be) but I
can't find the solution myself. All i want to do is click on a model in
my 3D world and reset it to it's starting position. I think I should be
using resetWorld to do this. How do I detect a model that has been
clicked?

Thanks

There's a technote on the Adobe site on the topic of Picking Lingo at:
[url]http://www.adobe.com/support/director/3d_lingo/picking_lingo/[/url]

You could use 'modelUnderLoc' or 'modelsUnderLoc' to find out what's under
the cursor being clicked.

And example behavior may be:

on mouseUp
pt = the mouseLoc - point(sprite(1).left, sprite(1).top)
ClickedModel = sprite(1).camera.modelUnderLoc(pt)
if ClickedModel <> 0 then
if ClickedModel.name = "name of model" then
go to "restart" -- or do whatever you want
end if
end if
end

regards
