ECHO 360 and Module Quizzes - ANSWER-ECHO 360 and Module Quizzes An assembly cannot be nested inside an existing assembly; only parts can - ANSWER-False I bring a part into an assembly in SolidWorks, and click the OK check mark at the top right. This will.. - ANSWER-leave the part in a floating state; align component with the assembly origin I bring a cube into an assembly and mate-coincident one of its edges to a fixed edge. It now has how many DOF's - ANSWER-2 Every part brought...

Total runout (runout tolerance)[two arrows] - ANSWER-3D control for rotating parts relative to a datum axis. (cylindrical surface = controls circularity, straightness, taper, concentricity, and surface profile; flat surface = controls wobble, perpendicularity, and flatness) Basic dimensions (those with a box around them)... - ANSWER-are theoretically exact and locate the perfect position of features from clearly identified datums The feature control frame - ANSWER-contains the geometric ch...

True? - ANSWER-No; there are major differences The term "IPS" in SolidWorks refers to... - ANSWER-measurement units To create an extrusion, I must first draw a sketch on a surface. True? - ANSWER-Yes, but the surface must be flat What are the fundamental types of sketch constraints? - ANSWER-Geometrical and dimensional To clock a hexagonal feature so that it rests horizo...

descriptive geometry - ANSWER-A 2D graphical construction technique used for geometric analysis of 3D objects Optimization - ANSWER-Modification of shapes, sizes, and other variables to achieve the best performance based on predefined criteria Why are most cave drawings and hieroglyphics not considered to be engineering drawings? - ANSWER-Becuase they were mostly documentation of lifestyle, not instructions on how to build something In what ways did the design of military fortifications...
