Most designers would no doubt agree that the most excruciating phase of any project is when one is facing a sheet of paper with nothing yet on it: nothing to develop, nothing to modify, nothing to disagree with. Extending this first stage unduly is obviously to be avoided. It is thus desirable to decide upon a preliminary structure as soon as possible, using whatever means may be available. Doing so is particularly important in structural design because analysis begins from a proposed structure having a known geometry.
