AutoCAD 2D Tutorial - 165 - Chapter 19 Blocks and AttributesAutoCAD 2D Tutorial - 166 - Creating Local Blocks (BMAKE) 19.1 1. Choose Draw, Block, Make. or 2. Click the Make Block icon. or 3. Type BMAKE at the command prompt. Command: BMAKE or BLOCK 4. Type the name of the block. 5. Pick an insertion point. 6. Select objects to be included in the block definition. 7. Click OK. Note You cannot use DIRECT, LIGHT, AVE_RENDER, RM_SDB, SH_SPOT, and OVERHEAD as valid block names. Insertion pointAutoCAD 2D Tutorial - 167 - Inserting Blocks 19.2 1. Choose Insert, Insert Block or 2. Click the Insert icon from the INSERT toolbar. 3. Type INSERT at the command prompt. Command: INSERT 4. Choose the name to insert a local block and Browse...to insert a Wblock. 5. Choose the insertion point, scale, and rotation of the block. Block Inserted with a zero degree rotation angleBlock Inserted with a ninety degree rotation angleAutoCAD 2D Tutorial - 168 - Typing Insert (-INSERT) 1. Type - INSERT at the command prompt. Command: -INSERT 2. Type Block name to insert. Insert block name or (?) type name 3. Pick An insertion point. Insertion point: pick point 4. Press ENTER to keep the same x scale factor as the original block. X scale factor <1>Corner / XYZ: 5. Press ENTER to keep the same x scale factor as the original block. Y scale factor (default=X): 6. Press ENTER to keep a rotation angle of zero. Rotation angle <0>: or 7. Pick A rotation angle.AutoCAD 2D Tutorial - 169 - Control the Color and Linetype of Blocks 19.3 The objects in an inserted block can retain their original properties, can inherit properties from the layer on which they are inserted, or can inherit the properties set as current in the drawing. You have three choices for how the color, linetype, and lineweight properties of objects are treated when a block reference is inserted. - Objects in the block do not inherit color, linetype, and lineweight properties from the current settings. The properties of objects in the block do not change regardless of the current settings. - For this choice, it is recommended that you set the color, linetype, and lineweight properties individually for each object in the block definition: do not use BYBLOCK or BYLAYER color, linetype, and lineweight settings when creating these objects. - Objects in the block inherit color, linetype, and lineweight properties from the color, linetype, and lineweight assigned to the current layer only. - For this choice, before you create objects to be included in the block definition, set the current layer to 0, and set the current color, linetype, and lineweight to BYLAYER. - Objects inherit color, linetype, and lineweight properties from the current color, linetype, and lineweight that you have set explicitly, that is, that you have set to override the color, linetype, or lineweight assigned to the current layer. If you have not explicitly set them, then these properties are inherited from the color, linetype, and lineweight assigned to the current layer. - For this choice, before you create objects to be included in the block definition, set the current color or linetype to BYBLOCK.AutoCAD 2D Tutorial - 170 - Wblock Command 19.4 Writes objects to a new drawing file. 1. Type WBLOCK at the command prompt Command: WBLOCK 2. Type A drawing name (and location). 3. Type A block name if a local block already exists. Block name: name or 4. Press ENTER to create a block. 5.
