• Addon for accurate CAD-style modeling. Create anchored guide points and edges, draw lines and primitive shapes in place, automatically create faces with closed geometry, precisely move, duplicate and rotate geometry around the scene, and cut meshes using extrude.
• Construction Lines is a tool for accurate CAD style modelling. Build snappable guide points and edges, draw lines and primitive shapes in place, automatically create faces in closed geometry, precisely move, duplicate and rotate geometry around a scene and cut-through meshes with extrude.
• Guide edges and points allow for a construction workflow where guides are set and models are then constructed within these guides. The guides won't interfere with model geometry and can be toggled off and on when required. Guide edges will disappear when working outside of Construction Lines and neither Guide Edges nor Guide Points will be rendered.
• Construction Lines allows for rectangles, circles, and arcs to be drawn in place from precise snap points on existing geometry or guides. These can be drawn from anywhere on a 3D model without the need for Blender's 3D cursor to define an Add location. Drawing shapes onto existing faces will automatically cut into the existing face.
• Construction Lines works seamlessly between Object and Edit modes in Blender.
