If you picked the вЂConvert to blockвЂ™ option under вЂObjectsвЂ™ your original geometry will have also have been converted to a block. The block is now defined in the current drawing and can be inserted at any time. Add a little extra information, if you want.Pick the entities you wish to include in your block.To define a block for the current drawingД¬reate the entities you want to use in the block definition. Note: I donвЂ™t recommend this technique if you want to reuse your blocks or share them with others! The вЂBLOCKвЂ™ command Right click and choose вЂCutвЂ™ (Windows shortcut Ctrl + X), right click again and choose вЂPaste as BlockвЂ™ (Ctrl + Shift + V). Select the entities you want to turn into a block. You have a few different options for creating blocks If you want any of your entities in the block to be independently changeable, put your entities on any Layer and make sure that the properties of the objects are set to вЂBYBLOCKвЂ™. If you want any of your entities in the block to Inherit their properties from the current layer, put your entities on Layer 0 and make sure that the properties of the objects are set to вЂBYLAYERвЂ™. If you want any of your entities in the block to retain their original properties, put your entities on any layer apart from Layer 0 and make sure that any of the properties of the objects that you want to retain are not set to вЂBYBLOCKвЂ™ or вЂBYLAYERвЂ™. Each block needs a unique name, an insertion point and usually contains some entities. Planning your blockД«efore you create your Block you should consider the following points. You have the option to decide whether the block will always look the same, no matter what layer it is on, or whether it is possible to change each instance of the block to have different properties, or whether the block should inherit the properties of the layer it is currently on. The block definition will retain the information about the original layer, colour, and line type properties of the entities that are contained within your block. You can move your block to any layer you wish. Your block will always be inserted on the current layer. Attribute information can be extracted to a table or excel spreadsheet to form a schedule or a bill of materials. The Attribute definition is contained within each block, but the information that the attribute holds can be different for each instance of that block. An attribute is a label or tag that contains information. Block AttributesД«locks can also contain Attributes. Each entity could be on any layer and could have different colour, line weight and line type properties. Lines, arcs, circles, text or even other blocks. If you edit a block you are editing the block definition and all instances of that block will change.ДЄ block definition can contain any number and any kind of entities i.e. You can access the block definition via any instance of that block. The block definition is stored in the magical ether of your drawing file. A copy of a block is know as an вЂinstanceвЂ™ of a block definition. A block вЂ DefinitionвЂ™ and a block вЂ InstanceвЂ™. Unlike groups you cannot change the geometry in one block without changing all the copies of that block.* Block Definitions and InstancesДЄutoCADВ Blocks have two parts. Unlike AutoCADвЂ™s Groups If you change the geometry that is contained within a block all copies of that block will also update. AutoCAD blocks are a way of collecting geometry together into one object which you can use repeatedly in your drawings.
