Joinery software

Joinery software supports the carpenter (master) in planning the joinery . This is the basis for the processing of wood for a building z. B. a roof truss . Usable joinery software, which has been developed since the early 1980s, has largely replaced the conventional methods of determining joinery dimensions, the 1: 1 elevation on the drawing board , the true-to-scale elevation (usually 1:10) and the arithmetical joinery (using a calculator and formulary). The beam planning can be carried out more precisely and faster with beam programs.

The different beam processing software programs are based on

• 3-D CAD cores
• 2-D CAD or
• Computing programs

each taking into account the special requirements of the carpenter .

First, a floor plan is entered with the default roof pitch , roof overhang and eaves height . These inputs are facilitated by various aids (e.g. special input dialogs, graphic explanations, etc.). The first intermediate result is a roof design . The individual roof surfaces are more or less automatically equipped with structural timbers ( rafters , hip or valley rafters , purlins , posts, fillet clips, ceiling beams, wall timbers and much more). In contrast to free CAD, the timbers are tied to the roof surface (so you do not have to specify a reference point) and distributed evenly over the surface. In addition, the ends are already cut at the right angle, so that a three-dimensional roof model is easily created on the screen.

After the model is ready, dimensioned floor plans and sectional plans are generated from it. All the timbers entered are summarized in a timber list, which is sorted in length and sent to the sawmill with optimized waste .

A higher level of the joinery software already enables the machine cutting of all wood on computer-controlled joinery systems.
