|
|
|
|
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.
|
|
When the first point is defined, it is possible to add straight segments.
|
|
Each segment will start at the end point of the previous segment or at the
|
|
first point of the sketch, if there are no validated segments.
|
|
|
|
The way of segment construction can be selected by the <b>Coordinates Type</b>
|
|
radio buttons.
|
|
|
|
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.
|
|
|
|
A segment can be defined by:
|
|
- <b>Cartesian coordinates</b> of its second end, which can be either:
|
|
- \b Absolute coordinates X, Y and Z, or
|
|
- \b Relative coordinates DX, DY and DZ with
|
|
respect to the previous applied point,
|
|
|
|
- <b>Angular coordinates</b> of its second end specified by:
|
|
<ul>
|
|
<li> 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. </li>
|
|
|
|
\image html 3dsketch_angle_rel.png
|
|
|
|
<li> the \b Radius (i.e. the distance from the origin) and an \b Angle in the chosen plane in \b Absolute mode </li>
|
|
|
|
\image html 3dsketch_angle_abs.png
|
|
|
|
In both angular modes you can additionally specify the following:
|
|
|
|
<li> the second \b Angle (latitude) </li>
|
|
|
|
\image html 3dsketch_2angles_rel.png
|
|
|
|
or
|
|
|
|
<li> the \b Height </li>
|
|
|
|
\image html 3dsketch_angle_height_rel.png
|
|
|
|
|
|
</ul>
|
|
|
|
<b>TUI Command:</b> <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.
|
|
|
|
<b>TUI Command:</b> <em>sk = geompy.Sketcher3D()</em>
|
|
|
|
Returns an instance of Sketcher3D interface <i>sk</i>.
|
|
|
|
Use the below examples and see the \ref gsketcher.Sketcher3D "Sketcher3D"
|
|
interface documentation for more information.
|
|
|
|
Our <b>TUI Scripts</b> provide you with useful examples of the use of
|
|
\ref tui_3dsketcher_page "3D Sketcher".
