<\/p>\nThe objective of this tutorial is to acquire fundamental knowledge of Grasshopper through a simple definition that employs various functions and components. The intention is to construct an entire bridge starting from a single point, which will be converted into lines, surfaces, volumes, and ultimately, a bridge. Since all the stages are parametric, it allows for endless possibilities to generate countless variations.<\/p>\n
<\/p>\n
Let\u2019s start with a point set in {0,0,0}<\/p>\n
The bridge will need 3 points, one to start, one to end, this will be the length of the bridge, and in between a point to design the curvature of the bridge. This point will be on the line drawn by the two others and will be able to move along the line and in height.<\/p>\n Now let\u2019s create the point on the line<\/p>\n Add a Point on Curve<\/p>\n We have our 3 points.<\/p>\n The middle one will be raised create the arch. Then, a curve is created linking first, raised midpoint and last<\/p>\n The curve is copied horizontally to obtain the bridge width. This is done by moving the curve Y direction.<\/p>\n Add a Loft to create the bridge deck, Nota, the Relay is put to have a better presentation, create a Relay by double clicking on the Wire.<\/p>\n The bridge can have a thickness by extruding the loft surface.<\/p>\n Let\u2019s first create the vertical bars that hold the handrail<\/p>\n Finish by transforming lines into solid objects. Here, extruded polygons are used, this is one solution among many. For the handrail, it\u2019s also possible to use a Tube which is easier\u2026but creates more polygons.<\/p>\n Whole definition<\/p>\n The bridge at its first definition is done<\/p>\n Kindly complete this form<\/a> to provide feedback on this exercise.<\/p>\n Thank you<\/p>\n\n\n\n to Follow…inserting Parametric Bridge Into Unity.<\/p>\n\n\n\n <\/p>\n","protected":false},"excerpt":{"rendered":" The objective of this tutorial is to acquire fundamental knowledge of Grasshopper through a simple definition that employs various functions and components.
