Win32 and 64, English

To make the notches in intersecting parts (3D-solids) connect cross.

General Usage Instructions

You can choose the items before the CrossPiece command call. But if you want to call a program option, you must first deselect all objects and then call the CRS. You can select two or more solids simultaneously. The selection could accidentally get any foreign objects - it is not scary. The program will only work with Solid. In the process of selecting the items you see in the console 3 options:

  • Inverse - this option allows you to change the direction of pulling out of parts from the slot. To be specific, first recommended selecting 1 solid, enter this option and press enter. You will be prompted to choose the second solid.
  • Gap - the program will ask the size of the gap, which should be left between the items for free movement. The gap is recommended in cases when you are not sure that your production will receive the exact material thickness you drew. For example, suppliers of particle boards can afford the sheet thickness from 15.8 to 16.5mm. In this case, I recommend a 0.3mm gap. This gap will be placed on each side of the parts. Thus the groove is 0.6 mm wider than the parts. Those you can say you have entered number doubles.
  • Backlash - This option also creates a gap between the parts, but the gap will be made only at the ends of the cutouts. This will allow the details to be pushed into the cross deeper than they are located in the assembly. Usually, this gap is used to compensate for the diameter of the milling cutter, which parts are made on the CNC milling machine.


The program is designed for only a limited number of components and connection methods. The main surface of the parts should be flat; the ends of the parts should not overlap with each other. In some cases, the geometry of solids is so complex that further processing becomes impossible and Autodesk® AutoCAD® shows error eGeneralModelinglFail. This is not a fault of my program. You can try to redraw such a solid again.

When the parts are drawn a little out exactly program cannot understand the way of dismantling the cross-piece. In this case, you can see: that one part likely surrounds another. To help the program just move items in the direction of dismantling the cross-piece at least a little bit.

If more than 2 parts are joined by crosspieces, the program will try to make cutouts from the same side of the part to disassemble the crosses in one direction. But if this program does not succeed - the help program just moves items in the direction of dismantling cross-piece at least a little bit.

The program always sets History=Non for all solids.

Settings are stored in the Windows registry under the current user. 

Follow the messages on the console. There may be program messages.
