Changing Properties Using the Changing Properties Using the Properties Palette Properties Palette Properties of 3D objects can be modifi ed using the Properties palette, which is thoroughly discussed in AutoCAD and Its Applications-Basics. Learning Objectives After completing this chapter, you will be able to: ✓ Change properties on solids. wblock: A block definition saved as a separate drawing file.173 Copyright Goodheart-Willcox Co., Inc.
block definition: Information about a block stored within the drawing file.
block: An object, such as a symbol, saved and stored in a drawing for future use. If you draw block objects on a layer other than layer 0, place all the objects on layer 0 before creating the block. Draw the objects for all blocks on the 0 layer and then assign the appropriate layer to each block when you insert the block. If you origi- nally create block objects on the 0 layer, the block inherits the properties of any layer you assign to the block. The 0 layer is the preferred layer on which to draw block objects. To do this, you must understand how layers and object properties apply to blocks. Selecting a Layer Identify the appropriate layer on which to create block elements before drawing the objects. Draw the objects once and then save them as a block for multiple use. Fasteners, punches, subassemblies, fi xtures, and appliances are examples of items to consider converting to blocks. Review each drawing and project to identify items you can use more than once. Constructing Blocks Con s tructing Block s A block can consist of any object or group of objects, including annotation, or can be an entire drawing. You also have the option to scale, rotate, and adjust blocks to meet specifi c drawing requirements. You can insert blocks as often as needed and share blocks between drawings. The WBLOCK command saves a wblock as a separate drawing fi le. The BLOCK command stores a block within a drawing as a block defi nition. The ability to create and use blocks is a major benefi t of drawing with AutoCAD. ✓ Edit a block and update the block in a drawing. Learning Objectives After completing this chapter, you will be able to: ✓ Create and save blocks. 729 Copyright Goodheart-Willcox Co., Inc.
