Sometimes the world of CAD terms can be confusing. If you don't know your planer surfaces from your bezier curves, then we're here to help!
BricsCAD's guide to CAD terms

A technique of dragging a 2D dimensional boundary, face or polygon into a 3D object, either along a single axis or with a taper. How to use extrude in BricsCAD.
When the corner between two connected lines is replaced by a rounded arc. See: 'Chamfer'. How to use fillet in BricsCAD.
Geometric dimensioning and tolerancing. A system for defining engineering tolerances.
In BricsCAD grips display as small colored squares at key-points on selected entities. (The default color is green). More information on grips.
A circular line that travels along the relative z-axis. It can maintain a constant circumference or can taper. Similar to the thread of a screw. How to use helixes in BricsCAD.
(Industry Foundation Classes) An official standard, open file format that is used to specify building data. More information on IFC. More information on IFC.
A view or drawing style where objects appear the same size regardless of their relative position in space. All axes are drawn at an angle of 60°, edges of a straight-sided object are drawn parallel to each other. More information on isometric drawing.
Just Checking You're Still Reading (not a real CAD term).
A line on a drawing, typically with an arrow, that links an item to a piece of text or a balloon. How to add leader lines to BricsCAD.
A family of computer languages. Affectionately referred to as Lost In Silly Parentheses given the high number of parentheses used in the coding language. Learn how to get started with LISP.
A 3D shape created between 2 or more 2D objects. How to use loft in BricsCAD.
The widest width of an ellipse.
Mechanical Computer-Aided Design
The narrowest width of an ellipse.
The virtual area in which the 3D model resides.
A unique identifier of an entity in the drawing.
The zero 'starting point' of an object or block.
Objects placed horizontally or vertically in a drawing. See Ortho Help for Otho Mode.
The area used to create the printing and plotting layout. More information on model space and paper space in BricsCAD.
A higher level assembly part. Sometimes the term "Grandparent" or "Great-Grandparent" is used at high levels.
A set of constraints used to control the size of the geometry. The value can be manually altered and animated in BricsCAD. Learn more about parametrics in BricsCAD.
See -- Tool Palette.
A view that mimics the 'real world view'. Displaying objects as smaller when they are further away. The top and bottom edges of an object are not parallel.
A closed polyline. How to use polygons in BricsCAD.
Two or more, connected lines, curves or arcs. They can be closed or open. How to use polylines in BricsCAD.
A flat area or boundary in any given direction.
A flat surface in any given direction.
Simple drawing objects; a point, line sphere, pyramid, arc, etc.
Various attributes of a given object or objects.
A command to refresh the current drawing references and resolution. How to use regen in BricsCAD.
