You should be able to move the cylinder into the block with a normal move command. After that, select both objects and click on the Subtract button (or use the subtract command keyboard input) and I think it may ask you which piece you want to keep, so you'll select the rectangular block and hit enter.

The Subtract button is located on your solid editing ribbon and it's one of the three buttons that looks like a venn diagram.

Load the "Visual Styles" toolbar and it will give you a couple of viewing/rendering options.

You can also use the RENDER keyboard command, but I find that takes too long.

That doesn't look quite right, but I'm not sure what would be causing those strangely angled lines. Perhaps those edge effects need to be turned off.

Looks like you cut the surface but didnt remove... ill fire up my work laptop in a bit and see if i can get you a better answer. The strange lines on the surface are there because its connecting the nodes from the 'cylinder' to create the surface.

Good call, that's probably what happened!

[knownothingmags]

so i got the line problems fixed and the lighting,

now:
when i go to subtract an object from another how do i get things perfectly center?

[knownothingmags]

is there just a centering tool, to apply to obejects?

[sQuidvision]

no, no centering tool... not really anyhow. The best thing to do is draw "construction lines" to locate the center of your circle... draw your circle... then delete your construction lines.

I also looked into your subtract question... what might be easier for you is to use the "press/pull" tool. Draw your circle on the face you want to cut it out of, then "press" it through the depth of your shape.

LMK if you have more questions... i work for an autodesk reseller and answer tech support stuff all day... i may as well continue into the evening

awsome. thankyou for the tip with the construction line.

Question,

do i need to put sizes and scaling in my drawing, or is that all applied by the cnc or mill operator?

im lost when it comes to the production side of my drawing.

anyone who can get me some light on this would be helpful.

and of course more questions to come,

Generally speaking you draw everything on cad applications at true scale. If its large or very small you might scale it to print it.

or
if i want a peice to be 10mm x 10mm x 2mm i would draw it on cad 10 x 10 x 2?
