3D CAD/CAM is the core technology for shoe sole mould in the footwear industry and develops towards specialization. Benefits of CAD/CAM in the mould manufacturing are: Total modeling for rapid generation of design concepts and variations; Reverse engineering from existing models or parts; Easy design modification and morphing capability
A reference dimension is a dimension on an engineering drawing provided for information only. [1] Reference dimensions are provided for a variety of reasons and are often an accumulation of other dimensions that are defined elsewhere [2] (e.g. on the drawing or other related documentation). These dimensions may also be used for convenience to ...
Using the auxiliary view allows for that inclined plane (and any other significant features) to be projected in their true size and shape. The true size and shape of any feature in an engineering drawing can only be known when the Line of Sight (LOS) is perpendicular to the plane being referenced. It is shown like a three-dimensional object.
The fact that the inner circle is drawn with a solid line instead of dashed identifies this view as the front view, not the rear view. The side view is an isosceles trapezoid . In first-angle projection , the front view is pushed back to the rear wall, and the right side view is pushed to the left wall, so the first-angle symbol shows the ...
View of a CAD model of a four-cylinder inline crankshaft with pistons. A 3D CAD system (such as KeyCreator, Autodesk Inventor, or SolidWorks) first produces the geometry of the part; the technical drawing comes from user defined views of that geometry. Any orthographic, projected or sectioned view is created by the software.
Geometric modeling is a branch of applied mathematics and computational geometry that studies methods and algorithms for the mathematical description of shapes. The shapes studied in geometric modeling are mostly two- or three- dimensional ( solid figures ), although many of its tools and principles can be applied to sets of any finite dimension.
An exploded-view drawing is a diagram, picture, schematic or technical drawing of an object, that shows the relationship or order of assembly of various parts. [ 1 ] It shows the components of an object slightly separated by distance, or suspended in surrounding space in the case of a three- dimensional exploded diagram.
Descriptive geometry is the branch of geometry which allows the representation of three-dimensional objects in two dimensions by using a specific set of procedures. The resulting techniques are important for engineering, architecture, design and in art. [1] The theoretical basis for descriptive geometry is provided by planar geometric projections.
