Shape CreationThe shape creation is one of the most flexible operations. Many different options exist to create the desired models. The following sections provide a basic overview of the available tools. Please refer to the specific manual pages for details.Material Each shape is assigned to a Material that will describe its material properties and its color. The materials are all shown in the navigation tree. Component The shapes are also associated to "components." Each shape must have a unique name within a certain component. Components are useful to quickly manipulate a larger part of the model. Basic Shape Creation The easiest way to create a shape is to define a "primitive." The following table shows the ribbon controls icons, their names and their location in the ribbon.
To create such a primitive, you will first need to activate the particular operation as shown in the table. This will lead you to the interactive shape generation mode where you may define the shape's parameters using the mouse (while in this mode, press F1 for more information). After you have finished all necessary steps (or pressed the ESC key) a shape parameter dialog box will open showing a summary of all parameters for this shape. Within this dialog box, you may change the parameters and finally create the shape. After the shape has been created, it will appear in the navigation tree under it’s Material folder. Slots and Vents Slots are used to represent a narrow aperture in
a thin metal face. It is intended for apertures that are too narrow to
be effectively modeled as features in the geometric model. A slot
can be created by Modeling: Shapes Vents are used to model perforated metal screens,
which are commonly used as windows or ventilation panels on metal enclosures.
For frequencies at which the width of the individual apertures is significantly
smaller than half a wavelength, these screens are only weakly penetrable
to electromagnetic fields. A vent
can be created by Modeling:
Shapes Blend and Chamfer Edges The simplest modifications of shapes are the blend and chamfer edge operations. To chamfer or blend edges, you will first have to
pick these edges. Afterwards,
you may activate the proper tool by choosing Modeling:
Tools Finally, a dialog box will appear where you may define the chamfer width or the blend radius. Transformations Transformations
may be applied to any shapes by selecting the shapes and then choosing
Modeling:
Tools Align Use the align
feature to position a selected model at a common interface with the current
model. You may activate the alignment by choosing
Modeling: Tools Extrude and Rotate Picked Faces It often becomes useful to extrude
or rotate
already existing faces in the model. Therefore, you may
pick a particular face and the activate the Extrude
Face (Modeling:
Shapes Boolean Operations Boolean operations
are a very common way to produce complex shapes. With these operations,
you may Add (Modeling:
Tools Loft Between Picked Faces A more advanced operation to create new shapes is
lofting between
profiles. This operations requires two faces to be picked
between which the loft will be placed. Afterwards, you may activate the
loft operation by
choosing Modeling:
Shapes Finally, a dialog box will appear where you may adjust the tangency of the lofted surface to the adjacent faces. Shell or Thicken Sheet One of the most advanced operations for shape generation is the shelling operation. For shelling, you must first select a shape. If you select a solid shape, you may additionally pick faces of the shape that will be opened during the shelling operation. Finally, you may activate the shelling
operation by choosing Modeling:
Tools Solid to Sheet Conversion Convert to Sheet:

The operation Modeling: Tools Simplify Sheet
Metal: Use the action Modeling: Tools Bend Sheet This operation allows to bend a planar sheet on a solid. For this bending operation, you must first select the planar sheet you want to bend. You can activate the bending
operation by choosing Modeling:
Tools Local Coordinate Systems Besides the ability to create the shapes along the axes of the global x/y/z coordinate system, it is also possible to define local coordinate systems or working coordinate systems (WCS). The usage of these coordinate systems allows the generation of structure elements with an arbitrary orientation in space. Furthermore, the local coordinates allow the construction of new model elements based on the faces on already existing ones.
