What is the Helix command in AutoCAD?
Creates a 2D spiral or 3D spring. Use a helix as a sweep path for the SWEEP command to create springs, threads, and circular stairways. The following prompts are displayed. Sets the center of the helix base point.
Where is Helix command in AutoCAD?
Type helix on the command line or command prompt and press Enter. Specify center point of the base on the viewport or drawing area of AutoCAD. Specify the base radius or diameter of the helix. For example, 4.
What is loft in AutoCAD?
The loft command in AutoCAD is used to create 3D solid or surface. The 3D solid or surface is formed within the space between various cross sections. The cross-sections determine the outer shape of the solid or surface. To create a 3D object using LOFT, we are required to specify at least two cross-sections.
What is sweep command in AutoCAD?
The 2D sub-object or object is swept along an open or closed path to create a 3D surface or solid using sweep command. The object enclosing the area is swept to create a 3D solid or surface, but an open-ended object is swept to create only a 3D surface.
What is Nurbs in AutoCAD?
NURBS stands for nonuniform rational B-spline curves. In AutoCAD, you can treat a NURBS surface as a 3D spline with fit points. … They also enable better control of the surface; and by using different densities of fit points on AutoCAD 3D surfaces, you can control the degree of precision of the surface.
What is the command for donut?
A donut consists of two arc polylines that are joined end-to-end to create a circular shape. The width of the polylines is determined by the specified inside and outside diameters. If you specify an inside diameter of 0, the donut is a filled circle.
What is Circle command?
The circle command is used to draw a circle by specifying the center point and radius. … Type Circle or C on the command line and press Enter. Specify the center point of a circle on the workspace or viewport. Specify the radius of the circle.
What is the equation of helix?
it is traced on the hyperbolic cylinder , as well as the surface , which is a surface of revolution when a = b. Curve studied by Catalan in 1878. The catenary helix is the generatrix of the minimal helicoid. x = cosh u cos v, y = cosh u sin v, z = sinh u.
What is a loci helix?
Description. A Helix is the locus of a point travelling with constant linear velocity, axially along the outside of a cylinder as the cylinder rotates with constant angular velocity. The axial distance travelled by the point for each revolution of the cylinder is known as the pitch.
What is the helix curve?
A helix, sometimes also called a coil, is a curve for which the tangent makes a constant angle with a fixed line. … Helices come in enantiomorphous left- (coils counterclockwise as it “goes away”) and right-handed forms (coils clockwise).
How do you draw a spiral curve?
You can create a spiral curve between any two points, such as the ends of a line or even two other curves. Click the “Alignment” tab and choose “Modify.” Click “Geometry Editor.” Locate the “Alignment Layout Tools” toolbar, and choose “Free Spiral-Curve-Spiral (Between Two Entities).”
What is AutoCAD best used for?
AutoCAD stands for Computer-Aided Design. This software used for designing and drafting. It allows a user to conceptualize ideas, product designs and drawings to the required level of technical accuracy, perform rapid design calculations and simulations in the field of manufacturing industries.
Why is AutoCAD so good?
When you’re using AutoCAD, it’s easy to zoom in and out and pan to other areas of the drawing. This is particularly useful when you’re working on large or complicated designs. The interface is easy to navigate, with various tools enabling you to view your drawing from different distances and perspectives.
What is the Presspull command doing in AutoCAD?
The Presspull command in AutoCAD 3D is used to create an area formed by the closed boundary. Or. It is used to pull an enclosed boundary. It can also be used to create a 3D solid in case of the selected circle or interior of the bounded area. The objects, such as arc, can be used to create a 3D surface.
What is sweep commands?
Sweep features are defined by using custom 2D cross-section (or face) moved along a pre-set path to create a 3D shape or surface. With the sweep method, the user defines a 2-D or 3-D guide curve, in addition to creating the cross-section.
