Tiemen's addons

Profile Rails Extruder is a Blender addon that extrudes a flat face profile into 3D space along a rail. Unlike Blender's curve bevel, the profile shape stays unchanged by the rail's direction rather than tapering.

Cross Section Maker is a Blender add-on that creates a cross-section from a mesh. The cross-section can be projected to the XY plane so it exports cleanly as a DXF file for use in CAD software.

Hole Maker is a Blender add-on for cutting holes in a mesh with an exact diameter, depth and position. You pick a vertex as the hole's center and press 'Make Hole(s)' in Edit Mode.

Mirror/Chop is a Blender add-on for modifying meshes in edit mode. It mirrors a mesh across any plane and splits geometry by choosing a plane or three points, chopping the mesh at that plane.

Axis Addon for Blender creates alignment axes in edit mode to help position objects, especially around axis and round holes. It builds axes through planes or three points and adjusts the 3D cursor accordingly.

Mesh Stuff is a Blender addon that works in edit mode to simplify modeling tasks. It bundles four tools — Distribute, Rotate, Plane to Plane, and Mirror — plus guide lines, all available from the side panel.

Object To Point Rail is a Blender addon that distributes mesh objects along a rail built from selected edges. The rail sets both the location and direction of each object, without modifiers.

Disassembler And Nesting is a Blender addon that flattens and sorts the components of a model, such as a cabinet, into the XY plane to help turn a Blender design into a physical object.
