VTube Rectangular Tubes

Back to VTube-STEP Back to VTube-LASER

As of version 1.82, VTube-STEP and VTube-LASER can draw, calculate, and measure rectangular tube shapes.

Drawing Rectangular Tubes

VTube can draw rectangular or square tubing. The dimensional controls are in the Part Setup menu of both STEP and LASER modes:

VTube - Profile Shapes

Square Tube Set Width1 and Width2 to the same values to draw square tube. The rectangular fillet radius controls the four corner radii.

Rectangular - Bending "Easy Way" This profile orientation is referred to as the "easy way" bending in the tubing industry. The reason is because this orientation is easier to bend than a profile rotated 90 degrees to this.

Rectangular - Bending "Hard Way" You can switch the values in the Width1 and Width2 to rotate the tube shape into the "hard way" bending method.

VTube - Profile Rotations

Square Tube Rotation Set the Rectangular Angle to rotate the profile of a square tube relative to the plane of the first bend.

Rectangular Tube Rotation The same rotation feature works for rectangular tubing.

Measuring Rectangular Tubes

VTube measures rectangular and square tube shapes with the laser or ball probes. FILLET EDGE DETECTION:The laser scanning feature includes edge detection in order to remove the fillet from the plane calculations. In this image, see how VTube detects edge fillets and removes them automatically from the calculation of the planes. TRUE CENTERLINE LOCATION: The process and logic automatically calculates the location of the centerline from the true surface data. The nominal width data is not needed to find the centerline. OVAL TUBE with FLAT SIDES: VTube can also measure rectangular oval tube shapes with large radius edges using a ball probe. (This profile shape of tube is often used on exercise equipement like Cybex VR3 machines, and in custom exhaust like SpinTech Performance.)
