Hello,

I've Noticed that I can draw shapes such as rectangles or circles inside others rectangles and circles and when extruded the shapes are cutout. But I tried to draw out two circles and joined them by two drawn tangent lines and then trimmed the inside lines. The remaining shape was an outline that resembled a keyhole. When extruded, this drawing is not cut out like the preset circles and rectangles, how come?

Thanks again.

Hello,

I am still learning the forum interface, when I try to click the insert image it only goes to an url and not to a file on my computer. I can give a quick example. I extruded a circle, then in top view in wire frame mode on top of the extruded circle, I drew an arc line and then attached a straight line to the bottom of it to form a semi circle. I would like to be able to either extrude or cut a hole with semi circle that I drew.

Thanks

Use the cutout tool to remove the material from the cylinder in you example. The key is making sure you have the geometry on the correct plane. Goto to the workplane menu and turn the workplane on so its visible. The "c" key is alos a shortcut to quickly toggle the workplane.

It's ok that the keyhole shape is on the bottom, you can still use the cutout tool. You can pick the vector the cutout tool uses so it cuts from bottom to top of cylinder.

The "c" key toggles thru the workplanes as you keep pressing the c key.

The keyhole you have should be able to be cut with the cutout tool.

Maybe the shape itself is the problem. Here is what happens, I grab the cut out solid tool and left click on one of the keyhole lines. I am given the option in the first posted picture. The entire shape will not light up, just one line at a time. Then it gives me the error in the next picture. Also, how do you pick the vector.

Thanks

And sorry for so many questions.

I right clicked on the line and selected the chain, but it just flickers for a second and the lines do not remained highlighted.

I figured out that I can get it to highlight when in the selection tool (black arrow). When I click select chain it does highlight the entire chain, but does not give me the vector prompt. I doubled checked the line connections I think they look good.

Sorry but I do not understand what Pick first point on cylinder and then pick second point on cylinder means.

Griff

Eureka!!!! Thanks so much. I'm sorry that this has taken the better part of a day to figure out.
