Workplane has no real geometry

Re: Workplane has no real geometry

Workplane /W2 is the active workplane, and this workplane does NOT contain any 2D geometry.........Your active workplane must have a closed 2D profile in order to perform any machining operations. (hence the error) For What It's worth. The workplane is only a visual representation of an infinite plane where you will create 2D geometry. Workplane borders will grow in order to display any geometry you create on them. (although there is a default starting size) Do not worry about the position. You can use construction geometry to define an origin for any profiles you need to create. (Or, you can create your new workplane by using the point and direction method, which will give you a workplane with a U-V origin at the selected point) Also, make sure you understand how to use the catch mode. Unless you set your catch to allow you to select 3D geometry when you create 2D geometry, any lines you try to build over existing 3D edges will not necessarily be on that edge.

Re: Workplane has no real geometry

Thanks Mike but this n bit mutch to swallow for now, i will have to do some more reading because i dont realy understand what you are saying. I drew the flat shape of the block with 2d co pilot, then i rotated it and extruded it to the thickniss i wanted, now it looks to me that i cant mill on the extruded part but only on the flat 2d part....is that where i am making the mistake, maybe im not understanding some basic fundamentals? Anyway im ading a picture of the part that i want to draw, maybe you or anyone else can advise me on how i should start this project.

Re: Workplane has no real geometry

I've totally ignored your dimension on your drawing and created on with similar shape just to show how I would do it. Normally I don't keep workplanes because they are not needed when using this product, but I left them on so you could see how I did it. W1 is the workplane that I used to create the main shape, then extruded it. I then created W2 and put the holes on the face where they needed to go (you might have to learn how to use construction geometry to get them placed correctly). Then W3 was created and used to put the notch in the part. Notice that you can only see the geometry in W3 because that is the one that is active. The other two planes are inactive. As I said before, I'd delete the workplanes once you're done with that machining operation to avoid any confusion.

Re: Workplane has no real geometry

Thanks Garry and everyone else for your input..i am slowly getting the hang off this...i managed to drill a hole and milled one side, not to drwing dimensions at all!!! but that will come later, now im just trying everything out. You guys helped a lot because when you start with a new Drawing package and you hit a snag like this you just need a few tips in the right direction.
