A |
|
| absolute position | A sheet coordinates. |
| active view | A view from which you create any element: another view or 2D dress-up. The view from which section views, section cuts and detail views will be created. This view generally corresponds to either the front view or the isometric view. |
| aligned section view | A section view created from a cutting profile defined from non parallel planes. In order to include in a section certain angled elements, the cutting plane may be bent so as to pass through those features. The plane and feature are then imagined to be revolved into the original plane. |
| associative detail view |
A detail view associated with a 3D element. |
| associativity | In the Drafting workbench, the ability of child view(s) to follow the behavior of the parent view: moving, scaling. |
| attribute | In the Drafting workbench, the graphical and/or geometrical properties inherited from 3D element. |
| auxiliary view | A view in a direction not necessarily vertical or horizontal. In order to show the true shapes, it is necessary to assume a direction of sight perpendicular to planes that are perpendicular of the curves. This auxiliary view, together with the top view, completely describes the object. |
B |
|
| background sheet | A sheet dedicated to frames and title blocks. |
| background view | A sheet dedicated to frames and title blocks. |
| back-clipping | A back-clipping removes all the elements behind a pre-defined plane. It can only be applied on an extracted view. Aback-clipping plane is a plane used for generating a back-clipping. |
| bill of material | A piece of information inserted into the active view of a CATDrawing document. For this, you can be either in the working view or in the background view. |
| breakout | A breakout is a partially removed section which allows visualizing a particular element in the view. A breakout view is one not in direct projection from the view containing the cutting profile. In other words, it is not positioned in agreement with the standard arrangement of views. A breakout view is often a partial section. |
| broken view | A view that allows shortening an elongated object, using two profiles corresponding to the part to be broken from the view extremities. |
C |
|
| callout | A graphical representation of a cutting profile. |
| child view | A view generated from a parent view. |
| clipped view | A view modified via a clipping profile. |
| clipping profile | A zone to be kept and visualized in a view. |
| cross hatching | A symbolic representation in the form of a pattern used to display a cut area. |
| cut area | The cut surfaces on a section view or section cut. |
| cutting profile | A set of planes used to define a section view or section cut. |
D |
|
| datum feature | An element defining a contacting surface on a part. |
| datum target | An element defining a contacting surface on a part and represented by spherical or pointed locating pins. |
| design tree | Area of the document window reserved for viewing the design specifications of a drawing, presented in the form of a tree structure. |
| detail view | A view corresponding to a zoomed particular area to be visualized. This area to be visualized is defined by a circle or a given polygon. This view is computed using a boolean operator from the 3D |
| drawing | The root feature. Sheets are aggregated in the drawing. Views are aggregated in the sheets. |
| dress-up | A graphical attribute of a 2D element. |
F |
|
| FD&T view | A view that is extracted from a 3D part that is assigned 3D tolerance specifications and annotations. |
| filter | A restriction on elements to be cut in a section view or section cut, or elements to be seen in a projection view. |
| first angle projection method | An orthographic
representation of the views comprising the arrangement, around the principal view
of an object, of some of all of the other five views of that object.
With reference to the principal view, the other views are arranged as
follows: the view from above is placed underneath, the view from below is placed above,
the view from the left is placed on the right and then the view from the rear is placed on the left or on the right, as
convenient. (Ref. No. ISO 10209-2:1993) |
| frontal plane | A plane of projection upon which the front view is projected. |
| front view | A projection view obtained by drawing perpendiculars from all points on the edges of the part to the plane of projection. The plane of projection upon which the front view is projected is called the frontal plane. |
I |
|
| isometric view | A 3D view that represents a part according to a given projection plane. This view allows a perspective visualization. To produce an isometric projection (isometric means "equal measure"), it is necessary to place the object so that its principal edges make equal angles with the plane of projection and are therefore foreshortened equally. |
L |
|
| lock | A locked view is a view in which any graphical modification of the generated 2D elements is forbidden. |
M |
|
| main view | The view which supports the geometry directly created in the sheet. |
O |
|
| object | In the Drafting workbench, there are two kinds of object: activated and selected. The view frame of an activated object is displayed in red. |
| offset section view /cut | A section view created from a cutting profile defined with several parallel planes. In sectioning through irregular objects, it is often desirable to show several features that do not lie in a straight line by offsetting or bending the cutting plane. |
| overlay | In a multi-model context, all passive elements are called overlayed elements. |
P |
|
| parent view | A reference view from which another view is generated (for example a front view from which a section view will be created). The view frame of the parent view is displayed in red. Typically the front view is a parent view. See also child view. |
| part | A 3D entity obtained by combining different features in the Part Design workbench. |
| pattern | A graphical representation used to represent a sectioned/cut part. A same representation is used for the different parts of the resulting section or section view. |
| projection view | A view conceived to be drawn or projected onto planes known as planes of projection. A transparent plane or pane of glass representing a plane of projection is located parallel to the front surfaces of the part. |
Q |
|
| quick detail view | A view corresponding to a zoomed particular area to be visualized. This area to be visualized is defined by a circle or a given polygon. This view is directly computed from the 2D projection. |
S |
|
| section cut | A view representing the intersection between the 3D geometry and the cutting profile. |
| section profile | See cutting profile. |
| section view | In the Drafting workbench, a view representing the intersection between the 3D geometry and the cutting profile, and all the 3D geometry located behind the cutting profile. |
| simple breakout | A simple breakout removes locally a sectioned part perpendicularly to the current view plane. You will then be able to visualize the remaining visible inside part. |
| sheet | A set of views. Several sheets may be created in the Drafting workbench. |
| standard | The international conventions that are supported in the Drafting workbench: ANSI, ISO and JIS. |
T |
|
| template | In the Drafting workbench, an object that is included in the document (for example, the title block). |
| third angle projection method | An orthographic
representation of the views comprising the arrangement, around the principal view
of an object, of some of all of the other five views of that object.
With reference to the principal view, the other views are arranged as
follows: the view from above is placed above, the view from below is placed underneath,
the view from the left is placed on the left and the view from the rear is placed on the left or on the right, as
convenient. (Ref. No. ISO 10209-2:1993) |
| title block | A frame which contains the title block. |
U |
|
| unspec breakout | An unspec breakout operation removes locally a 3D part. It allows visualizing the inside of a 3D part. It can only be applied to an extracted view. |
| unfolded view | A projected view that is created from a Sheet Metal part in order to include in a section certain angled elements. As a result, the cutting plane may be bent so as to pass through those features. |
V |
|
| view frame | A square or rectangular frame that contains the geometry and dimensions of the view. |
W |
|
| wizard | An assistant for views to be automatically generated once the CATDrawing document is opened. These views can then be modified as if they had been manually created one after the other. |
