<h1>OCC 3D Viewer</h1>
|
|
|
|
<p><span style="font-weight: bold;"><B>OCC (Open CasCade) 3D viewer</B></span>
|
|
has been developed on the basis of Open CASCADE Technology. This is the
|
|
default viewer for Geometry Module, providing good representation of construction
|
|
and transformation of geometrical objects. Only this viewer allows to
|
|
work with groups and sub-shapes. This viewer can also work in Mesh module,
|
|
however, it doesn't allow to visualize meshes. </p>
|
|
|
|
<p> </p>
|
|
|
|
<p>The functions of OCC viewer are available via its Viewer Toolbar. Buttons
|
|
marked with small downward triangles have extended functionality which
|
|
can be accessed by locking on them with left mouse button. </p>
