## Creating a BRep entity from scratch

In this article, we create a BRep entity by defining its vertices, edges, faces and shells. const double radius = 10, height = 20, centreToCentre = 20, offset = 3; Point3D[] vertices = new Brep.Vertex; vertices = new Brep.Vertex(0, -radius); vertices = new Brep.Vertex(centreToCentre, -radius); vertices = new Brep.Vertex(centreToCentre, +radius); vertices = new Brep.Vertex(0, +radius); vertic… by Alberto Bencivenni | July 28, 2023 | Share

At the time of writing, due to a singularity, we need to set the radius as 19 units instead of 20. // Sketch 1 var sk1 = new devDept.Geometry.ConstraintSolver.Sketch(); // Add origin point SketchPoint origin1 = sk1.AddOrigin(); // Lines var l1 = sk1.AddLine(-20, -60, -20, -100); var l2 = sk1.AddLine(-20, -100, 20, -100); var l3 = sk1.AddLine(20, -100, 20, -60); // Mid point var p1 = sk1.AddPoint(20, -100); sk1.AddConstraintMidP… by Paolo Bencivenni | July 20, 2023 | Share
