Hey guys,

Once more I am trying to wrap my head around 3D modeling. I have been drawing with autocad (2D) and draftsight for several years now. I have tried several different 3D drawing packages (turbocad ect.) and been completely frustrated with them. I am now going to try Sketch-up 8. I am working in a Mac enviroment if that makes any difference.

What I have so far is a 6" tall cylinder with a 2.5" diameter. I have a stepped hole bored down through the middle of the cylinder along the long axis.

What I am trying to do now is apply a .125" champher to the top and bottom faces.

Can anybody tell me how this is done?

Thanks,

Tim

not sure whats all on sketchup , but making 2 torus , 1 bigger , then subtracting one from the other leaveing a reverse champfer , then copy it and put it on the end and subtract it from the main part (ive only used bobcad , heeks , dolphin , so im not sure if you can do that )

On mine I select the edges I want champhered, click the drop down tool bar for champher, and specify the size and angle of the champher I want.

Then once again in the actual tool path I select a champher tool of a given angel and specify the cutting depth of the tool and the program will calculate the distance of the tool center from the edge

Of course this is a 3 axis mill rather then a lathe

Joe, are you using the free version of sketch-up 8 or the Pro version? I am using the free version and I don't find a champher tool under any of the drop down boxes or tool bars. is it maybe a plug-in?

Simplest method:-

1: Offset Tool : offset (copy) the corner edge 0.125" 'inwards' (creating a new circle on the cylinder end surface)

2: Move Tool: drag the corner edge down 0.125" (the chamfer is created between the two circles)

That animation is neat. Could you share how you created it? Was it done with Sketch-Up?

That animation is neat. Could you share how you created it? Was it done with Sketch-Up?I used the free version of 'Screencast-O-Matic' , saving the recording as an animated GIF. (That was a bit large for a forum post (~3Mb), so I reduced the quality in Jasc Animation Shop which got it down to <300kb.)

The prog is quite basic, but in a good way - simple to use and not too many options to worry about.

Start the prog, adjust the capture window size, (& select a mic or a webcam insert if required), start recording.......stop recording, and save in a variety of formats, + automatic upload to a YouTube account if available.

(The downloaded prog is here (http://www.screencast-o-matic.com/download) , not the on-line version which needs an evil Java plug-in .)

Cheers
