Brothersoft Editor: TouchCAD 3.6 is a combined 3D modeling and shape/image unfolding program focusing on the ability to generate complex 3D shapes and converting them into physically buildable models. The TouchCAD 3.6 modeling engine provides fast and advanced push-pull free form 3D modeling based on 3D-math curves. Features： New features for 2D drafting and documentation within the 3D environment. Shaded surface object in the drawing area whit individual settings for each object. Support for text in either 2D and 3D and with individual font and size settings. Support for 3D measurement lines, measurement chains and coordinate measurements in the 3D environment. Support for instructional arrows, dots or cross lines. New features in the rounded rectangles, ARC, Circle tools. Improved .STL file export. Improved DXF-AAMA support, used for exporting to cutters in the fabrics industry. Improved Control Point Resolution features with support for local modifications. Improved database processing within an integrated spreadsheet for processing object names, weight and center of gravity, Layer and color identity, 3D edge lengths, unfolded cutting lengths, labor and material costs. Support for material stretch compensation in the X and Y directions of the unfolded parts. Dramatically increased number of contextual menus, which dramatically reduce the number of tool changes. New contextual menus in the 3D environment for extracting control Rulers and cross curves, connecting objects with surface patches. New contextual menus in the Unfold for quicker panel nesting, finding lowest rotation of a given panel, aligning panels. New contextual menus in the Unfold for returning unfolded panels back to the 3D environment for after processing. New contextual menus in the Render mode for changing view and returning a rendering to the 3D working area as a background image. Background images are Now printable as an integrated part of a drawing. you can free download TouchCAD 3.6.2 now.
