Advanced Linework Elliot Gindis, in Up and Running with AutoCAD 2011, 2011 11.5 Spline Spline is a unique and valuable command. Its origins are in the mathematical field of numerical analysis, and it is called a piecewise polynomial parametric curve (or a NURBS curve, non-uniform rational B ...
Start the plug-in with the command C2PL or CURVES2POLYLINE in the command line or click on the icon in the toolbox or on the Add-in ribbon. The plug-in starts and you can choose objects to join or you can go to the settings with the ENTER button. ...
Invalid SPLINE flag (code 70): 11. Only types 8 (non-rational) and 12 (rational) are supported currently. (line=4580, cell=) I assume this is the reason for the straight lines sticking out. "11" means "periodic, non-rational SPLINE". ...
There are special case intersectWith() functions in the AcGeLinearEnt2d, AcGeCircArc2d, and AcGeEllipArc2d classes to find the points of intersection between two lines, a line and an arc, an arc and an arc, or a line and an ellipse. However, there is no general intersectWith() function...
(unlike theNumberingandManual Numberingprograms) is that the order of numbers is selected depending on the position of the object relative to a given line, polyline, or any other curve. In any case, the program will ask you to select one curve as a guide and will then assign numbers to ...
A 3D point list (in WCS) on curve-obj. Return Values Type: Real or nil A number if successful; otherwise nil. Examples Set OSNAP to tangent and select the point where the line is tangent to the curve: (setq selPt (getpoint)) (4.91438 6.04738 0.0) Determine the distance from ...
If a path line is not coincident with the center or if you want to project in an arbitrary direction, use the projectgeometry command. Join together the resulting splines with splinedit. Then perhaps create a ucs with the center of the sphere and 2 points of the curve forming...
// Otherwise we return false returnfalse; } } } You should see exactly the same behaviour as in the last post, but now the code works for all curve classes, such as Polyline, Polyline2d, Polyline3d, Line, Arc, Circle and Spline. comments powered byDisqus...
Although AutoCAD Civil 3D has a special line command for this scenario, (vanilla) AutoCAD does not. To draw a tangent line from the endpoint of an arc in AutoCAD, you'll need to do the following: Draw a line from the CENTER of the Arc to the ENDPOINT of the Arc...
Another way to get the points coordinates from Excel to AutoCAD is to just copy and paste. In AutoCAD start the "pline" command, copy the range with x,y points from Excel, paste into AutoCAD's command line. You may need an "enter" to end the command. Occupant (Mechanical) 31 Jan 14...
