Key enhancements introduced in\nversion 71.0 of D-Cubed 2D DCM<\/a> (2D Dimensional Constraint Manager) are described below.<\/p>\n\n\n\n

Curvature Continuity\n(G3) Constraint<\/strong><\/p>\n\n\n\n

2D DCM\nincludes a wide range of features for creating splines and controlling their\nshape, including the ability to specify the geometric continuity when two\nsplines meet. For example, splines can join with G1 (tangent direction)\ncontinuity or G2 (curvature) continuity. \nVersion 71 includes the ability to impose a G3 (curvature continuity)\nconstraint between splines or other curved geometry.<\/p>\n\n\n\n

The figure\nbelow shows two splines meeting at their ends. The curvature (shown by the blue\nlines) is the same on both sides of the joins, but the right hand side shows\nthe additional impact of the new constraint.<\/strong><\/p>\n\n\n\n

Bi-Scalable\nSets and Splines<\/strong><\/p>\n\n\n\n

Sets are collections of geometries which 2D DCM solves as if they are\nconstrained relative to each other without requiring the use of individual\ndimensions and constraints. 2D DCM supports rigid sets<\/strong> where the shape\nand size are fully defined, scalable<\/strong> sets<\/strong> which have the freedom\nto scale uniformly, and uni-scalable<\/strong> sets<\/strong> which can scale in one\ndirection, as if the set were being stretched. Constraints and dimensions can\nbe applied between the set members and other geometries in order to position\nthe sets, and to remove any remaining freedoms of the set. <\/p>\n\n\n\n

Version 71 introduces a bi-scalable set<\/strong>. This has two internal freedoms which permit\nscaling in two perpendicular directions whilst maintaining the underlying\nshape. The scaling directions need not be aligned to the axes.<\/p>\n\n\n\n

Splines can be controlled in a similar way, so it is\npossible to create rigid splines<\/strong>, scalable splines<\/strong>, uni-scalable splines<\/strong> and, from version 71, bi-scalable splines<\/strong>.<\/p>\n\n\n\n

About D-Cubed 2D DCM<\/strong>\n\nD-Cubed 2D\nDCM (2D Dimensional Constraint Manager) is widely acknowledged as the leading\n2D geometric constraint solver. In addition to driving the sketcher in many CAD\nproducts, 2D DCM is used in CAM, CAE and other geometry-based applications.\n\n\n\n<\/p>\n","protected":false},"excerpt":{"rendered":"
