Note:
When using many of the creation methods below, where U and V coordinates or digitised
points are specified; they are locked to the current workplane. Thus this should be
set first (in the Options dialog - Working Coordinate System page, see Options Dialog - Working Coordinate System Page) and then the graphics window set to the workplane view (via VIEW \ SET \ WORKPLANE
or WORKPLANE in the graphics window’s pop-up menu).
|
|
LINE \ POINT... |
|||
|
Brings up the Point dialog, which is used to create a point through one of the available methods. |
||||
|
|
LINE \ SEGMENT... |
|||
|
Brings up the Line Segment dialog (see Segment), which is used to create a line segment through one of the available methods. |
||||
|
|
LINE \ RECTANGLE... |
|||
|
Brings up the Rectangle dialog, which is used to create a rectangle through one of the available methods. |
||||
|
|
LINE \ ARC... |
|||
|
Brings up the Arc dialog, which is used to create an arc through one of the available methods. |
||||
|
|
LINE \ ELLIPSE... |
|||
|
Brings up the Ellipse dialog, which is used to create an ellipse through one of the available methods. |
||||
|
LINE \ POLYLINE |
||||
|
This gives the following options: |
||||
|
|
FREEHAND |
|||
|
If selected, the User is prompted to interactively digitise the points (in one of the graphics views) describing the polyline (series of connected line segments). Clicking the SPACE bar ends the digitisation process. |
||||
|
TABULATED... |
||||
|
Brings up the Generate Polyline dialog (see Tabulated Polyline/Spline), which is used to create a polyline from data points predefined (in the dialog) by the User. |
||||
|
LINE \ SPLINE |
||||
|
This gives the following options: |
||||
|
|
FREEHAND |
|||
|
If selected, the User is prompted to interactively digitise the points (in one of the graphics views) describing the spline’s control points. Clicking the SPACE bar ends the digitisation process. |
||||
|
TABULATED... |
||||
|
Brings up the Generate Spline dialog (see Tabulated Polyline/Spline), which is used to create a spline from control points predefined (in the dialog) by the User. |
||||
|
|
LINE \ NACA... |
|||
|
Brings up the NACA dialog, which is used to create an aerofoil cross section from the four digit NACA series. |
||||
|
|
LINE \ MODEL CUTS... |
|||
|
Brings up the Model Cuts dialog, which is used to create planar intersection curves, that means, sections, waterlines, buttocks and diagonals. |
||||
|
|
LINE \ DETACH EDGE |
|||
|
If selected, the User is prompted to interactively pick (from one of the graphics views) either the edge of a surface or segment of a curve, which is to be copied to create a new curve. |
||||
|
|
LINE \ FILLET... |
|||
|
Brings up the Fillet dialog, which is used to create an arc entity of a specified radius, tangent to two selected curves. |
||||
|
|
LINE \ OFFSET WIRE... |
|||
|
Brings up the Offset Curve dialog (see Offset Wire), which is used to create a parallel curve offset normal to the selected planar curve. |
||||
|
LINE \ EXTRACT CURVE |
||||
|
Lets the user point to an edge of a face in a surface from which a continuous curve in the surface is extracted. |
||||
|
|
LINE \ DELETE EDGE |
|||
|
If selected, the User is prompted to interactively pick (from one of the graphics views) the segment of a curve to be deleted. |
||||
|
|
LINE \ REVERSE |
|||
|
If selected, the User is prompted to interactively pick (from one of the graphics views) the curve whose direction is to be reversed. |
||||
|
|
LINE \ TRIM |
|||
|
If selected, the User is prompted to interactively pick (from one of the graphics views) two curves. The first curve being trimmed at it’s intersection with the second. The segment of the curve that is retained is controlled by which end of the initial curve is selected by the User. |
||||
|
|
LINE \ EXTEND... |
|||
|
Brings up the Extend dialog, which is used to extend a selected curve by a specified length. |
||||
|
|
LINE \ JOIN |
|||
|
If selected, the User is prompted to interactively pick (from one of the graphics views) two curves, connecting them at a common start or end point, into a single curve, using the identity of the first curve selected. The curves must not intersect or overlap. |
||||
|
|
LINE \ INTERSECT |
|||
|
If selected, the User is prompted to interactively pick (from one of the graphics views) two curves. The crossing segments (of the two curves) are each subdivided in two, at their intersection point. |
||||
|
|
LINE \ SPLIT… |
|||
|
Brings up the Split dialog, which is used to split a curve (or curves), either at an orthogonal plane location or with a general surface. |
||||
|
|
LINE \ PROPERTIES |
|||
|
If selected, the User is prompted to interactively pick (from one of the graphics views) a curve, whose length is displayed in the Output Window. |
