    When making a revolved part with multiple features, I like to use simple sketches and add the features as model features, not in the sketch. However, every feature sketch requires that I add a revolve axis in the sketch, which gets very redundant. Is there a 3D axis command that I am not aware of that could be used as a common revolve axis? I would love an infinitely long axis that could be made by using the intersection of planes or a point and a plane. In fact, in the sketching environment I would rather create an infinitely long centerline or reference line rather than having to dimension the length of a construction line to do the same.

      There isn't any 3D axis command that I am aware of currently.

      It is possible to use a a line from previously created sketches as the axis for a revolve. What you could do is to just draw the axis on the first sketch and when you need to do a revolve on that axis, show that sketch and click on the axis line.

      Another possibility would be to create a sketch that has just the axis line, label it as 'Axis' so that it is easy to find later, and it will be readily available when you need it for a revolve or to dimension to it from other sketches.

      Thanks. I don't know why I didn't think of that. Maybe because sketches are "consumed" after a revolve or extrude and are hidden from view and hence from selecting.

      It is somewhat annoying that the line has to be on a separate sketch, and that the primary axis lines for the cardinal planes don't work...

    Is there a 3D axis feature? (2024)

    FAQs

    Is there a 3D axis feature? ›

    In mathematics, analytic geometry (also called Cartesian geometry) describes every point in three-dimensional space by means of three coordinates. Three coordinate axes are given, each perpendicular to the other two at the origin, the point at which they cross. They are usually labeled x, y, and z.

Three coordinate axes are given, each perpendicular to the other two at the origin, the point at which they cross. They are usually labeled x, y, and z.

    What is the XYZ axis in 3D? ›

    Y defines the up and down axis, X the left and right axis, and Z the forward and back axis. In the previous figure, the X coordinate defines the horizontal space in the scene, while Y defines the vertical space, and Z adds the third dimension by defining the depth to and away from the origin.

    Is the y-axis vertical in 3D? ›

    If a diagram (3D projection or 2D perspective drawing) shows the x- and y-axis horizontally and vertically, respectively, then the z-axis should be shown pointing "out of the page" towards the viewer or camera.

    How many axis are there in a 3D graph? ›

    There are a couple standard ways to graph points in three dimensions. The method this book uses is with the positive x-axis coming diagonally down to the left, the positive y-axis going diagonally down to the right, and the positive z-axis going up. In reality, the x and y-axes are coming out of the paper at an angle.

    What is a 3 axis? ›

    A 3-axis CNC machine is one that performs machining operations by moving its tool or the part along the X, Y, and Z axes. The cutting tool can be moved anywhere along the horizontal (X-Y) plane and cut into parts to specified depths (Z-axis motion).

    What is the 3rd dimensional axis? ›

    In three dimensions, we define coordinate planes by the coordinate axes, just as in two dimensions. There are three axes now, so there are three intersecting pairs of axes. Each pair of axes forms a coordinate plane: the xy -plane, the xz -plane, and the yz -plane (Figure 5).

    Which direction is the xyz axis? ›

    The x axis is in the plane of the screen and is positive toward the right and negative toward the left. The y axis is in the plane of the screen and is positive toward the top and negative toward the bottom. The z axis is perpendicular to the screen or keyboard, and is positive extending outward from the screen.

    Is there slope in 3D? ›

    The term "slope" is really a 2D term. If you''re talking about, say, a 3D terrain, then you can say that you have two different slopes, one in the x direction and one in the y direction, with the slopes being dz/dx and dz/dy.

    What are the 3D coordinates of the y-axis? ›

    The coordinates of any point on the y-axis will be as (0, y, 0) The coordinates of any point on the z-axis will be as (0, 0, z) Any point in the XY-plane coordinates is of the form (x, y, 0) Any point in the YZ-plane coordinates is of the form (0, y, z)

    What is the difference between 2D and 3D axis? ›

    In a nutshell: The terms “2D” and “3D” refer to the dimensions. 2D means an X and Y axis, like a photograph. We'll let the Mona Lisa demonstrate this here. 3D refers to three dimensions, X, Y, and a Z axis, which is how we experience the real world.

    What is the depth axis in a 3D chart called? ›

    A 3-D column, 3-D cone, or 3-D pyramid chart has a depth (series) axis, also known as the z axis, that you can change.

    How many axes does any 3D object have? ›

    What is the 3D printer axis? ›

    Step 4: Number 1- THE X, Y, AND Z AXES

    The X axis on a 3D printer is usually the lateral movement left to right (or vice versa), while the Y axis on a printer represents movement forward and back.

    Which axis is xy and z on a 3D printer? ›

    Y axis is always up/down, Z for depth, and X for left/right. In the 3D printing world the Z and Y axis have swapped places, which often makes me confused.

    What do the XYZ coordinates mean? ›

    Usually, the x-coordinate is measured along the east–west axis, the y-coordinate is measured along the north–south axis, and the z-coordinate measures height or elevation.
