![]() If you want to draw an horizontal line 100mm in length starting at (0,0), you activate the line tool, either click on the screen or input the (0,0) coordinates for the first point, then make a second click or input the second point coordinates at (100,0). Objects are drawn precisely to the intended size or dimension. Orthogonal (2D) views are drawn manually and intended for producing technical drawings (also known as blueprints). The traditional way of CAD drafting inherits from the old drawing board. To explain how the Sketcher works, it may be useful to compare it to the "traditional" way of drafting. A constraint solver calculates the constrained-extent of 2D geometry and allows interactive exploration of the degrees-of-freedom of the sketch.Ī fully constrained sketch Basics of constraint sketching The Sketcher workbench features "constraints", allowing 2D shapes to follow precise geometrical definitions in terms of length, angles, and relationships (horizontality, verticality, perpendicularity, etc.). Moreover, together with the PartDesign Workbench operations, the Sketcher also forms the basis of the feature editing methodology of creating solids. Together with boolean operations defined in the Part Workbench, the Sketcher forms the basis of the constructive solid geometry (CSG) method of building solids. Generally, a 2D drawing is considered the starting point for most CAD models, as a 2D sketch can be "extruded" to create a 3D shape further 2D sketches can be used to create other features like pockets, ridges, or extrusions on top of the previously built 3D shapes. Font: Here you can change fonts, size, font color, text layout, and apply bold, italic or underline.The FreeCAD Sketcher Workbench is used to create 2D geometries intended for use in the PartDesign Workbench, Arch Workbench, and other workbenches.Change colors: Change the color of any shape content using this tool.Border colors: Change the color of any shape borders you might have applied using this tool.Line: Change line thicknesses applied using Preview’s tools here.Adjust Color includes adjustment sliders for exposure, contrast, highlights, shadows, saturation, color temperature, tint, sepia, and sharpness. If working with images the Adjust Color tool is available in this position. ![]()
