TRUE or FALSE
2. The amount that any one dimension can vary is referred to as the tolerance.
TRUE OR FALSE
3. While the MMC of a feature is important, for certain design calculations, it is important to also understand the LMC.

What is the number one thing needed to ensure a perfect sketch? To know how big a feature is and where it is located, the dimensions on a drawing come in what 2 types? 4. What are the 3 main views used on an orthographic drawing? What 3D shape usually has 1 view and occasionally 2 views on an orthographic drawing? 6. Almost all drawings are made from what 2 pieces of geometry? Draw a hidden line and explain what it is used for: Draw both types of center lines and explain what they are used for LIST and EXPLAIN the use of 3 sketching/manual drawing tools: 1. Name the 4 methods of measuring with a dial caliper. What is meant when it is stated that a dimension has a tolerance of ± .010? 12. Why is an isometric drawing added to an orthographic drawing? 13. Define SCALE as it pertains to a sketch or drawing: Define proportion as it pertains to a sketch or drawing:arrow_forward
- A datum when used in manufacturing is primarily used for? Define the functional relationship to another feature on a part, or they have a functional relationship in an assembly. They are the origin from which many Geometric tolerances are measured. Datums are used to describe how one part must fit or align to a mating part. A datum should be placed on the smallest surface of the part to be sure that the mating part would fit. Datums assure that parts will always fit together.arrow_forwardhow do i make this in creo parametric using grouping and pattern featuresarrow_forwardDraw the isometric view of the following objects.
