What is Donut command in AutoCAD?
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. A donut is drawn at each point specified until you press Enter to end the command.
What is Ellipse command in AutoCAD?
The Ellipse is a general command to create ellipse on the AutoCAD display. We can create the ellipse by specifying the two-point on an axis and the endpoint on another axis. The first axis and the second axis of the Ellipse can be determined either as minor or major axis, depending on the specification.
What is Helix perforce?
Helix Core, formerly Perforce Helix, is the company’s version control software for large scale development environments. The Helix Version Control System manages a central database and a master repository of file versions. Helix Core clients fall into roughly five categories: Git, command, GUI, web, and plugin.
What is Loft command 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.
What is perforce p4?

How do you find the area of a helix?
I need the formula for calcuating the surface area of a helical coil. I have the pipe diameter, coil height, # of turns, and pitch, but can not seem to remember the formula used. Any help would be appreciated. Thanks.
What is the pitch of helix?
The pitch of the DNA helix is 3.4 nm.
How is helix pitch calculated?
The pitch is the distance one has to travel up or down the helix to get the vector I to make a full turn about the axis of the superhelix. A local approximation to the pitch can be calculated as the ratio of the length of D to the angle made by I, and I, (the latter divided by 2n).

What is spiral curve?
The spiral is a curve of varying radius used to gradually increase the curvature of a road or railroad. Spiral curves are used primarily to reduce skidding and steering difficulties by gradual transition between straight-line and turning motion, and/or to provide a method for adequately superelevating curves.
What is revolve in AutoCAD?
The Revolve command in AutoCAD 3D is used to create a 3D solid or surface by sweeping the object through its axis at a predefined angle.
What is sweep tool in AutoCAD?
