\page using_measurement_tools_page Using measurement tools

\n Measurement tools in GEOM are necessary for getting different data
concerning created or imported geometrical objects. They are:

<ul>
<li>\ref point_coord_anchor "Point coordinates"</li>
<li>\ref basic_prop_anchor "Basic properties"</li>
<li>\ref center_mass_anchor "Center of mass"</li>
<li>\ref inertia_anchor "Inertia"</li>
<li>\ref normale_anchor "Normal to a Face"</li>
<li>\ref boundaries_anchor "Check Free Boundaries"</li>

<li>\ref bounding_box_anchor "Bounding box"</li>
<li>\ref min_distance_anchor "Min. distance"</li>
<li>\ref angle_anchor "Angle"</li>
<li>\ref tolerance_anchor "Tolerance"</li>
<li>\ref whatis_anchor "WhatIs"</li>
<li>\ref check_anchor "Check"</li>
<li>\ref check_compound_anchor "Check compound of blocks"</li>
</ul>

\anchor boundaries_anchor
<br><h2>Check Free Boundaries</h2>

\n Detects and highlights  wires and edges that are not shared between
two faces and are considered a shape's boundary.

\n <b>TUI Command:</b> <em>(NoError, ClosedWires, OpenWires) =
geompy.GetFreeBoundary(Shape),</em> where \em Shape is a shape to be
checked, \em NoError is false if an error occurred while checking free
boundaries, \em ClosedWires is a list of closed free boundary wires,
\em OpenWires is a list of open free boundary wires.

\anchor faces_anchor
<br><h2>Check Free Faces</h2>

\n Highlights all free faces of a given shape. A free
face is a face which is not shared between two objects of the shape.

\n \b NOTE: This functionality works only in VTK viewer.

\n \b Result: a list of IDs of all free faces, containing in the shape.
\n <b>TUI Command:</b> <em>GetFreeFacesIDs(Shape),</em> where \em Shape is
a shape to be checked.

\anchor bounding_box_anchor
<br><h2>Bounding box</h2>

\n Returns the dimensions of the bounding box for the selected
geometrical object.

\n <b>Result:</b> Displays the dimensions of the bounding box of a
geometrical object in the form of Python Tuple (Xmin, Xmax, Ymin,
Ymax, Zmin, Zmax).
\n <b>TUI Command:</b> <em>geompy.BoundingBox(Shape),</em> where \em Shape
is a shape for which a bounding box is computed.

\anchor min_distance_anchor
<br><h2>Min. distance</h2>

\n Returns the minimum distance between two geometrical objects and
the coordinates of the vector of distance and shows the vector in the viewer.

\n <b>TUI Command:</b> <em>geompy.MinDistance(Shape1, Shape2),</em>
where \em Shape1 and \em Shape2 are shapes between which the minimal

<br><h2>WhatIs</h2>

\n General information about the selected geometrical object is the
list of types and quantities of all topological entities, composing
the shape.

\n <b>TUI Command:</b> <em>geompy.WhatIs(Shape),</em> where \em Shape is a
shape from which a description is returned.

\image html measures8.png

\n <b>Kind of Shape</b> field characterises the
whole shape. If there is no additional information available for the
shape, <b>Basic Properties</b> button will be disabled, otherwise it
will show a dialog with information about
dimensions, position, orientation and other parameters of the shape.

\n <b>TUI Command:</b> <em>geompy.KindOfShape(Shape),</em> where \em Shape is a
shape from which a description is returned.

\anchor check_anchor
<br><h2>Check</h2>

\n Checks the topology of the selected geometrical object and returns
True if it is valid. Check also geometry checkbox allows to test the
geometry as well.

\n <b>Result:</b> Boolean.
\n <b>TUI Command:</b> <em>geompy.(theShape, theIsCheckGeom = 0),</em>
where is theShape is the shape checked for validity.

\anchor check_compound_anchor
<br><h2>Check compound of blocks</h2>

\n Checks whether a shape is a compound of glued blocks. To be
considered as a compound of blocks, the given shape must satisfy the
following conditions:
<ul>
<li>Each element of the compound should be a Block (6 faces and 12 edges);</li>
<li>A connection between two Blocks should be an entire quadrangle face or an entire edge;</li>
<li>The compound should be connected;</li>
<li>Two quadrangle faces should be glued.</li>
</ul>

\n Informs of the following possible errors:
<ul>
<li>not a block;</li>
<li>not glued;</li>
<li>not connected;</li>
<li>extra or degenerated edge.</li>
</ul>

\n <b>Result:</b> Boolean; highlight in the viewer.
\n <b>TUI Command:</b>
<em>geompy.CheckCompoundOfBlocks(Compound).</em> Checks if the shape
is a valid compound of blocks. If it is true, then the validity flag
is returned, and encountered errors are printed in the python console.
