EM FHNode

Description
The FHNode tool inserts a FastHenry node object.



How to use
The FHNode object can be based on the position of a Draft Point object, or you can select the 3D location of the FHNode.


 * 1) Press the  button, or press  then  keys.
 * 2) Click a point on the 3D view, or type a coordinate and press the  button.

Alternatively, you can also:


 * 1) Select one or multiple Draft Point object(s)
 * 2) Press the  button, or press  then  keys. As many FHNodes will be created as the Draft Point objects, at the same coordinates of the Draft Points.

Options

 * To enter coordinates manually, simply enter the numbers, then press between each X, Y and Z component. You can press the  button when you have the desired values to insert the point.
 * Click the checkbox to toggle continue mode. If continue mode is on, the FHNode tool will restart after you place a node, allowing you to place another one without pressing the tool button again.
 * Press or the  button to abort the current command.

Properties

 * : the X coordinate of the node
 * : the Y coordinate of the node
 * : the Z coordinate of the node

Scripting
FreeCAD Scripting Basics.

The FHNode object can be used in macros and from the Python console by using the following function:


 * Creates a object.
 * is the Draft Point object whose position can be used as base for the FHNode. It has priority over, , . If no is given, ,, are used as coordinates.
 * x coordinate of the node, in absolute coordinate system.
 * y coordinate of the node, in absolute coordinate system.
 * z coordinate of the node, in absolute coordinate system.
 * is the node color, e.g. a tuple (1.0,0.0,0.0). Defaults to.
 * is the node size. Defaults to.
 * is the name of the object

The placement of the FHNode can be changed by modifying its property, or changing the ,, properties individually. Changing ,, modifies the node position in the relative coordinate system of the.

Additionally, the _FHNode class exposes these methods. The _FHNode class can be accessed through the FHNode object Proxy (e.g. fhnode.Proxy).


 * Get a containing the node coordinates in the absolute reference system


 * Get a containing the node coordinates relative to the FHNode Placement


 * Sets the node position relative to the placement
 * is a FreeCAD.Vector containing the node coordinates relative to the FHNode Placement
 * is a new FHNode placement. If, the placement is not changed


 * Sets the absolute node position, considering the object placement, and in case forcing a new placement
 * is a FreeCAD.Vector containing the node coordinates in the absolute reference system
 * is a new FHNode placement. If, the placement is not changed
