Using AutoCAD selection technique to improve drawing efficiency

AutoCAD in the selection of the editor has a lot of skills, we collect the summary here, I hope to help you.

In the selection of AutoCAD Editor, sometimes accidentally select an entity, at this point in the command does not end the need to cancel the command and restart, only to "select the target" after the prompt input remove carriage return, and then in the hint to select which multiple of the selected entity (of course not too much, otherwise difficult to choose!)) can be done.

When AutoCAD chooses to edit, input two letters like MN, you will find a large list of prompts in command line, including fence, WC, WF, etc., very convenient.

The user can select a target in AutoCAD with the mouse one by one to add the selected target to the selection set, in addition, AutoCAD also provides window (to type "W" Response to select object: or directly on the screen from right to left a rectangular box in response to select Object: Hint), crossing (to type "C" in response to select object: or to pull a rectangular box directly from left to right on the screen in response to the Select object: Prompt), Cpolygon (to type "CP" Response to select object:), Wpolygon (To type "WP" Response to select object:) to select a target in a variety of window ways.

where window and crossing are used for rectangular windows, and Wpolygon and Cpolygon are used for polygonal windows, in window and Wpolygon mode, entities are selected only if all parts of the entity are contained in the window. In the crossing and Cpolygon mode, the entity is selected as long as part of the entity is included in the window.

AutoCAD also provides a fence way (to type "F" Response to select object:) to select an entity, draw an unclosed polyline, and all the entities that intersect the polyline are selected.

When you choose a target, you sometimes accidentally select a target that you don't want to choose, and then the user can type R to respond to the "Select objects:" Prompt, then remove some of the selected targets from the selection set, type A, and then add the target to the select set. When the selected entity is close to another entity, hold down the CTRL key while the then click the left mouse button continuously, then the entity close to each other is displayed in high brightness until the selected entity is displayed in high brightness, then press the ENTER key (or the right mouse button) to select the entity.

AutoCAD can conditionally select entities, that is, ' filter response Select objects:. The 2000 version also provides a quickselect way to select the entity, function and filter similar, but the operation is simpler and convenient. AutoCAD provides the choice set of construction method is very strong, flexible and appropriate use can make the efficiency of cartography greatly improved.
