6.3.4. Center Constraint

This chapter should explain usage of the constraint Center. You can use it to position parts centered between other parts.

Using the Constraint

Open the file bg_uebung_center_constraint of owning user: uebung_bg. It contains a Frame (Kulisse), a cylinder and a block. The cylinder and block should now be positioned in the center of the square cut-outs in the frame using the Center constraint (refer figure "Positioning done").

First, click Assembly Constraints in the Assemblies Tab and Select the constraint Center . The function of the constraint can be altered using the subtype Dropdown (refer figure "Center Constraint").

If you want to position the axis of a part in the center between two surfaces, you have to use the Option 1 to 2.

To position the cylinder in the center of a cut-out, select the centerline of the cylinder and then two opposing surfaces of the first cut-out in this order. Repeat this process with the remaining surfaces of the cut-out. The cylinder should now be centered in the cut-out.

To position the block in the last cut-out, the Option 2 to 2 should be used. Select it and then select two opposing rectangular faces of the block and then two opposing faces of the cut-out in this order. Repeat this process for the remaining surfaces.

Now both parts should be centered in the cut-outs. Now you can use further constraints to fully constain both parts. (refer figure "Positioning done")
