A Connect object is useful for building a connecting bridge between two separate objects. Each object must have an open face or hole that specifies where the two objects are to be connected.

To use this object, delete a face on two Editable Mesh objects and then position the holes across from each other. Select one of the objects, and choose the Create Compound Connect menu command. Then, click the Pick Operand button, and select the second object. The Connect object builds the additional faces required to connect the two holes.

Filling object holes

If multiple holes exist between the objects, the Connect object attempts to patch them all. You can also use the button several times to connect a single object to multiple objects.

Caution 

The Connect object doesn't work well with NURBS objects.

The Parameters rollout includes a list of all the operands or objects involved in the connection. You can delete any of these with the Delete Operand button. The Extract Operand button lets you separate the Operand object from the Connect object.

In the Interpolation section, the Segments value is the number of segments used to create the bridge section, and the Tension value is the amount of curvature to use in an attempt to smooth the connected bridge.

The Bridge Smoothing option smoothes the faces of the bridge, and the Ends option smoothes where the bridge and the original objects connect.

Tutorial: Creating a park bench

The Connect object is best used between two symmetrical copies of an object that need to be attached, as with a table or bridge. For this tutorial, we use the Connect object to create a park bench between two end pieces.

Note 

Although the Connect compound object works fine, it requires both holes to have the same number of vertices. A more robust solution is the Editable Poly's Bridge feature.

To connect two ends of a park bench, follow these steps:

  1. Open the  Park bench.max file from the Chap 18 directory on the DVD.

    This file includes symmetrical ends of the park bench. One end was created by extruding a spline shape and using the ShapeMerge tool to cut matching holes on the inner facing surfaces. The Mirror tool was then used to create and rotate the symmetrical clone.

  2. Select one end of the park bench, and select the Create Compound Connect menu command.

  3. In the Pick Operand rollout, click the Pick Operand button, select the Move option, and click on the opposite side of the park bench.

    The two end pieces connect.

  4. In the Parameters rollout, select the Smoothing: Bridge option to smooth the seat of the bench.

Figure 18.15 shows the resulting park bench.
