What’s most impressive about Natural Sketch is that with a few simple strokes a designer can generate a 3-dimensional conceptual model built from a series of 2D sketches. Unlike SOLIDWORKS’s parametric approach to sketching, Natural Sketch is a drawing program that’s controlled via stylus and touchscreen, which allows designers to create shapes from lines that are sketched more naturally. Recently, Dassault decided to add its Natural Sketch program (once solely available in CATIA) to SOLIDWORKS’s Industrial Design Package. In those instances, 3D sketching can be the only way to create the geometry you require. To union all of these sketches and guides into a shape, designers have to invoke commands like boundary surfaces, lofts and sweeps.Įven after all of that work, sometimes SOLIDWORKS finds fault with your geometry and can’t build a surface from a compilation of sketches. In normal 2D modeling, complex surfaces can be made by drawing multiple sketches that are then related to one another by guide curves. Modeling a cable or any other off the shelf part may seem like a waste of a designer’s time, but they can be valuable.īut beyond wiring are there other uses for 3D sketching?
So, how does 3D sketching actually help designers? One of its biggest assets is its ability to quickly create wires, pipes and tubing that can to snake through space in three dimensions. Once in a desired spatial alignment, geometry can be added to any area that falls within that dimension. SOLIDWORKS allows users to toggle through the XY, YZ and ZX dimensions of the drawing environment by hitting the tab key. What’s different about 3D sketching is that instead of drawing on a single plane, 3D sketching can exist on multiple planes simultaneously. Just like its 2D counterpart, the 3D sketch tool creates geometry by using points, lines, splines and any other sketchable shape to define a profile.
SOLIDWORKS includes a 3D sketch tool to make the process of creating geometry that snakes or slides through 3D dimensions. While 2D sketching can ably define extrusions, holes, paths and other features, its uniplanar restriction is cumbersome, if not unworkable, when drawing some complex shapes. When it comes to nearly every CAD model, sketching is the basis for creating a 3D object.
