heal.abstract	Orthogonal arrays are used as screening designs to identify active main effects, after which the properties of the subdesign for estimating these effects and possibly their interactions become important. Such a subdesign is known as a "projection design". In this article, we have identified all the geometric non isomorphic projection designs of an OA ( 27, 13, 3, 2), an OA (18, 7, 3, 2) and an OA (36, 13, 3, 2) into k = 3, 4, and 5 factors when they are used for screening out active quantitative experimental factors, with regard to the prior selection of the middle level of factors. We use the popular D-efficiency criterion to evaluate the ability of each design found in estimating the parameters of a second order model.	en
