3D Geometric & 3D Dimensional Constraints Working with 3D constraints in BricsCAD is just like working with 2D constraints in AutoCAD. The difference is that they also operate in the z-direction. (AutoCAD has no 3D constraints.)Expressions and parameters can specify values and formulae for 3D dimensional constraints, just as AutoCAD does for 2D constraints. The 3D constraints are available in the Pro and Platinum editions of BricsCAD. The difference is that while the Pro version can solve constraints, only the Platinum edition can apply them. 3D Dimensional Constraints dmAngle3D applies 3D angle constraint dmDistance3D applies 3D distance constraint dmRadius3D applies 3D radial constraint 3D Geometric Constraints dmCoincident3D applies 3D coincident constraint dmConcentric3D applies 3D concentric constraint dmConstraint3d is a super command that applies any kind of 3D constraint dmTangent3D applies 3D tangency constraint dmFix3d applies 3D fix constraint dmParallel3D applies 3D parallel constraint dmPerpendicular3D applies 3D perpendicular constraint dmTangent3D applies 3D tangency constraint WORKING WITH 3D CONSTRAINTS For a tutorial on using 3D constraints, see the Assembly Drawings section later in this chapter. Accessing 3D Constraint Commands ÐÐ Enter the commands listed in the table above ÐÐ Open the 3D Constraints toolbar ÐÐ In the ribbon’s Parametric tab, select commands from the 3D Constraints panel ÐÐ From the Parametric menu, choose 3D Constraints 196 BricsCAD V17 for AutoCAD Users
3D Design Intent BricsCAD Platinum determines automatically what you were probably intending to design. This is known as design intent. When design intent is turned on, BricsCAD recognizes parts of 3D entities that ought to be edited together automatically. This is similar to the actions of another MCAD program known as Solid Edge, where the function is named “Live Rules.” AutoCAD does not provide design intent. Consider an object with several holes of the same size. When design intent is running, it recognizes that they all have the same diameter. When you change the diameter of one of the holes, BricsCAD changes the diameters of the others automatically. This is why design intent is also known as “automatic 3D geometry constraints recognition.” Unlike constraints, you cannot, unfortunately, apply design intent to specific areas of a model: design intent is universal. You can choose, however, which aspects of design intent you want operating. For instance, you can have BricsCAD recognize planes that are just parallel, coincident, or perpendicular to each other. I find it convenient to toggle settings through the Design Intent toolbar. Click the big red X to turn off design intent. Design Intent toolbar toggles settings Design intent settings are toggled through the dmRecognize variable; see table below. Setting the value negative turns off design intent, but retains the former value. dmRecognize Description On by Default 0 All off 1 Tangent surfaces of planes, cylinders, and cones 2 Coincident planes • 4 Parallel planes • 8 Perpendicular planes 16 Cylinders perpendicular to planes 32 Coaxial surfaces of cylinders and cones • 64 Equal radius on cylinders (or holes) and spheres • negative value All off, yet retains value of the previous setting There is a limitation to automatic feature recognition that’s common to all CAD systems: the engine works only with 3D solids that it recognizes. For BricsCAD, this means that design intent works with simple shapes — planes (flat faces), cylinders, cones, spheres — but not with bodies of arbitrary shape. The simple shapes can, however, be part of a more complex body. 6 Working in 3D 197
