Press down on the middle mouse button and move the mouse left or right.

See how those things are not where it looks like they are? That's because you didn't have your workplane set correctly when you drew them. Here is a really lengthy explanation I wrote for the blog.

Drawing in 3D requires an entirely different mindset from drawing in 2D. If youâ€™ve spent a good deal of time drafting 2D schematics youâ€™re used to thinking and drawing in 2D, that is with two axes, the x and y. If you want to indicate a spherical object you draw a circle. If you want to indicate a cylinder you might draw a circle or rectangle depending on which view of the object youâ€™re drawing. Likewise a cone might be represented as a circle or triangle depending on whether you are looking at it from the bottom or the side.

But, when we draft in 3D we are in a different environment altogether from start to finish. In 3D we work in 3 Dimensions from the very beginning. There isnâ€™t just an x and y axis. There is also a third axis referred to as the z axis. So in 3D we canâ€™t just draw a circle and tell the program itâ€™s a sphere. We have to actually draw a sphere. We canâ€™t just draw a circle and a rectangle and call them a cylinder. We must draw a circle and extrude it into a cylinder. This concept applies across the board. In 3D we are no longer drawing objects according to the way they would look if we were viewing them from a vantage point. We are drawing objects the way they actually exist, with three dimensions and in TurboCAD we have an infinite space to draw them in. The x, y and z axes on which we draw stretch out into an infinite virtual space.

This concept, while immensely powerful, presents a very unique problem. This infinite space in which we draw is 3 dimensional. It has an infinite width, length and height. But, we access it and view it through a computer monitor, a finite two dimensional surface. So when I click my mouse to draw a line, rectangle, circle or some other two dimensional object that I might later modify into a three dimensional shape how does the software know where I am clicking. I could be clicking literally anywhere. This is the unique problem and it is solved with a deceptively simple solution called the workplane, also known as the user coordinate system or UCS. Specifying and defining coordinate systems is how the software keeps track of where we are performing operations and where we are placing objects.

A 3D coordinate system is like three dimensional graph paper. It has an x axis, y axis and z axis. It also has an origin point â€“ the place where the graph begins, where x = 0, y = 0 and z = 0. From the origin point each of the axes stretches out, perpendicular from the others, to infinity. In TurboCAD there are three main coordinate systems, the world coordinate system, the user coordinate system and the entity coordinate system.

The world coordinate system is the coordinate system of the infinite drawing space. When the software first opens a new file you are looking straight down at the geometric plane defined by the x and y axes of the world coordinate system.

Part of the solution I'm going to post for you involves setting the workplane by facet.

This will be a good primer for you to understand what you're doing when you do that.
