|
|
|
|
3D Sketcher allows creating a closed or unclosed 3D wire, made of
|
|
consequent straight segments.
|
|
|
|
<b>Example:</b>
|
|
|
|
\image html 3dsketch4.png
|
|
|
|
To create a 3D Sketch, select in the main menu <em>New Entity -> Basic -> 3D Sketch</em>.
|
|
|
|
\image html 3dsketch_dlg.png
|
|
|
|
The first point of a sketch can be defined by \b Absolute coordinates X, Y and Z.
|
|
After this, it is possible to add straight segments.
|
|
|
|
Each segment starts at the end point of the previous segment or at the first point of the sketch, if there are no validated segments.
|
|
|
|
The second point of a segment can be defined in two different ways depending on the selected <b>Coordinates Type</b> radio buttons:
|
|
|
|
By <b>Cartesian coordinates</b> , which can be either:
|
|
- \b Absolute coordinates \b X, \b Y and \b Z, or
|
|
- \b Relative coordinates \b DX, \b DY and \b DZ with respect to the previous applied point,
|
|
|
|
By <b>Angular coordinates</b>, which include:
|
|
- the \b Length of the segment and an \b Angle in the chosen plane (OXY for example) in \b Relative mode. The angle is then relative to a local coordinate system with the last point of the sketch as origin.
|
|
|
|
\image html 3dsketch_angle_rel.png
|
|
|
|
- the \b Radius (i.e. the distance from the origin) and an \b Angle in the chosen plane in \b Absolute mode
|
|
|
|
\image html 3dsketch_angle_abs.png
|
|
|
|
In both angular modes you can additionally specify the following:
|
|
- the second \b Angle (latitude)
|
|
|
|
\image html 3dsketch_2angles_rel.png
|
|
|
|
- the \b Height
|
|
|
|
\image html 3dsketch_angle_height_rel.png
|
|
|
|
To validate a segment and to proceed with the definition of the next
|
|
one, click <b>Apply</b> button. \b Undo and \b Redo buttons,
|
|
respectively, remove or restore the last segment in the wire.
|
|
|
|
\n <b>Sketch Validation</b> button applies the wire, built by the
|
|
user, "as is".
|
|
\n <b>Sketch Closure</b> closes the Sketch by a straight line from
|
|
the start to the end point and applies it.
|
|
|
|
<h2>TUI Commands</h2>
|
|
|
|
<em>geompy.Make3DSketcher( [ PointsList ] )</em>
|
|
This algorithm creates a wire from the list of real values, which
|
|
define absolute XYZ coordinates of points. The Result of the operation
|
|
will be a \b GEOM_Object.
|
|
|
|
\note To make a closed wire using this TUI command, the first and the
|
|
last point should have the same coordinates.
|
|
|
|
\n Another way to create the 3D Sketcher in TUI is using Sketcher3D
|
|
interface.
|
|
|
|
<em>sk = geompy.Sketcher3D()</em>
|
|
|
|
Returns an instance of Sketcher3D interface <em>sk</em>.
|
|
|
|
Use the below examples and see the \ref gsketcher.Sketcher3D "Sketcher3D"
|
|
interface documentation for more information.
|
|
|
|
<b>TUI Scripts</b> provide you with useful examples of the use of
|
|
