In modo you are able to make use of the work plane as a guide to align objects with some degree of accuracy, but as André Löscher notes, the Snaps and Precision menu in modo can offer a much better workflow.
Using Modos Snaps and Precision Tools to align the edges of two cubes in 3D spaceAndré Löscher
Using the working plane requires a few steps to use them for the purpose of alignment, while the Snaps and Precision menu will end up saving quite a bit of time. The Snaps and Precision tools are faster because you can use the objects themselves for 3D alignment in relationship to each other. André walks through some of the features in modo’s Snaps and Precision Tools and demonstrates how to use them and their options.
