Sine wave autocad

Use the getint , getpoint with an initget 32 twist , distance , angle , and polar functions..? I didn't see your post until I was done typing mine, great link, Larry! I like this function however, I am really trying to find out how to draw one by specifying two points.

Another 'fun' one. Could work with any function. I like this one. Lee, DynFun is really neat. Glad you like it Mr Render. That is really cool! Grread is pretty sweet! Grread is great for visual effect, but useless for practical applications as you have no OSnap, Ortho, Tracking or any other standard functionality. GrRead is purely for tracking keystrokes, mouse movements - general user input. Any OSnap or other functionality must be imitated within the grread loop.

This is awosome and exactly what i want, drawing sin wave controlling amplitude decreasing increasing i am doing some FEA project. Anyway, I've incorporated dcl into lsp and you don't have to store it in support search path of ACAD - you can load it from anywhere - it should work - creates temp dcl file, use that dcl and at the end removes temp dcl Regards, M.

This month's request came from Ralph Ragan of Atlanta, Georgia. Ralph wants to draw a sinusoidal curve as a spline or polyline. This type of curve occurs in many situations, including a two-dimensional helix and screw threads. Normally this is quite time-consuming because it requires tracing a curve through many points that must be calculated or constructed.

The routine allows the user to select the periodic time equivalent to the pitch of a thread , the amplitude half the height for a thread , the number of cycles to display and the resolution or display accuracy of the curve. To see this prompt, you may need to set your Command window size to 3 lines by dragging the Command window splitter bar appropriately.

After you enter SC, the Sine Curve dialog box pops up as shown figure 1. You can select the period, amplitude and numbers of cycles as shown in the figure by changing the values in the appropriate edit boxes. The Resolution is controlled by a slider bar as shown. Sliding the bar to the left Lo decreases the resolution and sliding it to the right Hi gives the highest accuracy.

The resolution is actually the number of points per cycle that is used to define the curve. The lowest setting corresponds to 12 points per cycle, and the highest setting is points per cycle. The initial default value is in the middle of the slider at 72 points per cycle. In the example shown, the period is 1.

The resolution is left at its initial value. See the security advisory on the Autodesk Trust Center for more information. AutoCAD Forum. Turn on suggestions.
