Use the rectangle tool to draw the square. It will/should allow you to enter the dimensions for the sides.
Switch back to 3D and extrude the square.
Presto a lovely 2" x2" x 5" block of 12L14
I got most of the way there. Here is what I did:
I clicked create sketch.
Then selected the xy plane
Then clicked 2 point rectangle
Clicked on origin
Then moved the mouse to 2,2 and clicked again.
Then clicked on the house (home) view in 5he top right corner.
Then clicked on my rectangle.
Where is extrude?
Start with the XY plane as the drawing surface. Then select the draw rectangle anchored on the center instead of corner. Drop it on the origin of the sketch and then tab between fields to set the dimension. Hit ENTER to save. Then as David said, extrude to a height in either the positive or negative direction.
I assume you select xy by clicking on the top of the plane view block in the top right.
That did result in a 2D plane. But where is draw rectangle?
I think some screen shots of the "create sketch" button and selecting the plane etc may be in order.
Amen Phaxtris. But now I'm starting to create real work for others.......
I can't get to the more advanced examples you guys are making me drool over until I get a 3D block on my screen. It's that initial hurdle of getting the block that I'm missing.
