Select 2 or more solid and call the command DadoJoint (DDJ). When selecting multiple of solids, the program will check the contacts of each of the solid faces with faces of the other solids. It may take a long time. So do not select just too many solids. Any objects, except Solids will be discarded. If nothing is selected before calling the command - program will ask you to choose the parts.

Then the program will ask you to specify the dado depth. This request can be disabled in the options, but then you will not be able to configure the program from the command line.

Enter the dado depth or 0. Note that the command line at this point displays options for switching styles and for configuring the command.

Then everything happens automatically:

• The program finds contact regions and discards small ones. Contacts with the same face areas of both parts are also discarded, since in this case it is not clear how to make a dado.

• The region can be offset inward to create a stop pad along the perimeter of the joined beam. The stop will be the same on all sides. If you need to make stops on a sheet metal part only on two sides, and not on 4 (without reducing the thickness of the part), then you need to use the Tab-Slot command with one tab and start pads.

• The contact region is extruded into a solid. Usually, pulling is done strictly perpendicular to the contact plane. This means that a break will appear on the faces of parts approaching the contact plane at an angle. In most cases, this helps to make a dado that can be cut without tilting the cutter. But you can try to enable the "Extrude along the beam" option and the program will try to determine the direction of the part. If it is possible to determine the direction, then the tenon and dado will be extruded along it.

• This solid is added to the part with a smaller contact face area and subtracted from the part with a larger face.

• If necessary, the solid is increased by the amount of the gap and backlash before subtraction. Also, the subtracted solid can be extended to the edges of the part in which the dado needs to be made.

If there are many contacts, then the order of subtraction will be random and it is possible that one of the dadoes will spoil the other. Check the resulting dadoes and, if necessary, redo one by one.

The program settings are saved in the Windows registry, in the current user section.

Follow the messages on the command line. There may be program messages.

• The program works only in 3D, only with solids.

• The contact surfaces should be flat, they should be based on the Region, and not the Surface. Therefore, the contacts of imported solids may not be found.

• Sometimes there are crossing the dadoes and tenons from each other. As a result, erroneous connections may be obtained. It is recommended to check the results of the program and redo the connections again one at a time, consciously choosing the order.

• Settings "Dado across the entire part" will only work if the contact region is a rectangle. If there are holes in the joined details at the junction, the elongation will not work. The dado can be elongated in a maximum of two. If the joint is much shorter than the details, then the dado will end earlier than the edges of the part.

• When joining at an angle with extruding along a round beam, if a stop pad is also set, the tenon will turn out not round, but oval.
