ABSTRACT:
A universal parallel ruler is disclosed. The head of the ruler includes preset stoppers which are adjustably positioned according the three axes of the three-dimensional drawing. There are three stoppers. One is stationary, and two are adjustable. The scale can be selectively set to the basic three axes by locking engagement with the preset stoppers. The stationary stopper corresponds to the vertical axis Y whereas the adjustable stoppers may be angularly set and correspond to the remaining (X and Y) axes. A locking piece may be engaged with or disengaged from the preset stoppers so that the scales may be engaged with the preset stoppers after the stoppers have been angularly set as desired. Also, the three preset stoppers may be fixably or adjustably mounted on the ruler's protractor so that the three axes of the three-dimensional drawing may be independently set.
