Solid Modeling: Top-Down Pillow Block Description Build a half symmetry solid model of this pillow block. When you’re done, save the database to p- block.db. Counterbore 1.0R, 0.1875 deep Base 6 x 3 x 1 Web, 0.15 thick All dimensions in inches 1.75 Four 0.75D holes, 0.75 offset from corner Bushing, 0.85R Bracket 1.5R, 0.75 thick Solid Modeling: Top-Down Pillow Block 1. Enter ANSYS in the working directory specified by your instructor using “p-block” as the jobname. 2. Switch to isometric view: Click on the Isometric View Icon in the Model Control Toolbar Or issue: /VIEW,1,1,1,1 3. Create the base of the pillow block: Main Menu > Preprocessor > Modeling > Create > Volumes > Block > By Dimensions X1 = 0, X2 = 3, Y1 = 0, Y2 = 1, Z1 = 0, Z2 = 3, then [OK] Or issue: /PREP7 BLOCK,0,3,0,1,0,3
