【 Weak current College 】 AutoCAD blocks used in the figure must be of

Skilled in tiles characteristic and use figure block drawing, is each aspires to become an essential tool for AutoCAD expert. Although the composition of the tile of the object has its own layer, color, line style and line width, and other characteristics, but is inserted into the graph, chart block the object of the original layer, color, line style and line width characteristics often change. General books and journals in AutoCAD related only to the definition of the tile, insert and save content, but on the tiles into its constituent objects before and after General characteristics change of content is very less. Summary of changes, for the proper use of tiles, improving computer drawing and design makes sense of efficiency. This article discusses the tiles consists of General characteristics of an object is limited to the figure blocks object layer, color, style, and line width.

Discuss map blocks object layer, color, line style and line width changes related to layer features include layers and layer status. Layer settings in the Layer Properties Manager on the layer, layer styles and layer line width setting. Layer status refers to the layer of open and closed, the layer of unfrozen and frozen, layers of unlock and lock status and layer printable and non-print status, etc.


First, figure block inheritance object layer

In Figure block insertion, figure block 0 layer object changes to the Insert layer of the tile, figure block non-0 objects on layer intact. That is, the tile layer on the Central Plains non-0 if the object is inserted graphics file has the same name as the layer with the same name on its own layer, inserted graphics file layer settings unchanged. If the inserted graphic file is not associated with the same name as a layer, AutoCAD first inserted graphics file of the same name in new tiles, and inheritance graph block non-0 layer object resides layer settings, and then put the figure block non-0 objects on the same name as on their own layer. In short, if 0 layer is not plugged into the layer, the figure block 0 objects on the layer, the layer that is placed back into the layer of the tile; figure block non-0 objects on a layer, the layer remains unchanged, so we say non-0 layer object layers have inheritance. If 0 is inserted into the figure of the object is located in the block layer remains unchanged.

Figure block insert, if you close the Insert layer of the tile, will make the figure block and insert layer objects on layers with the same name are invisible, if you insert a layer is not 0, it will also make figure block level 0 is not visible on the object. Because that figure block 0 objects on the tile has been replaced by inserting layer, but figure block other layers (neither insert layer also non-0) on the object is still visible. However, note that if you freeze the insertion of the tile layer, regardless of the tiles in the object on which a layer, the whole figure blocks are not visible, not only figure block and insert layer objects on layers with the same name and figure block 0 objects on the diagram are not visible in a block of non-object on the Insert layer is not visible. If 0 is a non-insert layer, close or freeze level 0, the Central Plains to the tiles in level 0 visibility of the object has no effect. If you close or frozen layers are neither figure block insertion layer is not 0, causes the figure block objects on the layer is not visible.

Figure block insertion, you can always change the Insert layer of the tile, select a drawing object in the "Properties" on the toolbar, click the "layer status" drop-down list box drop-down button, and then click the layer. As noted above, if you freeze map block insert layer. Then in the layer into the whole figure block will not be visible, you can use this method to validate a layer is a layer of the tile in inserts.

If you insert a layer of the tile is neither 0 nor figure block objects in the layer which, when removed all objects on the layer (including inserted chart block), you can remove this layer. However, the object is located in the block layer, whether it is not a figure block insertion layer, even if the layer has no object, it cannot be deleted.

If the figure is split block after inserting (Explode), then the tile is located in the before insert in level 0, the tile insert and change the tiles into the layer object, and then insert from the tile layer back to 0. In short, the tile decomposition, tiles in different layers of objects resides layers "to his fellow" and revert to the tile insert before the object is located.

Second, the tile composition object color, line style and line width of inheritance

In order to facilitate the discussion, the first several terms agreed.

Bylayer settings is in drawing the current color, the current line style or the current line width is set to Bylayer. If the current color (the current line style or the current line width) use Bylayer setting, the color of the drawing object (line or line width) and the layer color (layer style or layer line width), so the setting is also referred to as Bylayer layer settings.

Byblock settings is in drawing the current color, the current line style or the current line width is set to Byblock. If the current color settings using Byblock, painted object's color to white (White); if the current line style settings using Byblock, drawing object style as the solid (Continuous); if the current line width using the Byblock setting, the width of the drawing object to the default line width (Default), the default line width for 0.25mm, default line width can also be reset, Byblock sets also known as set with block.

Explicitly setting is in the current drawing color, the current line style or the current line width is set to Bylayer, neither explicitly nor Byblock.

Bylayer block refers to the color, style, and line width is used to set the drawn graph Bylayer; Byblock block refers to the color, style, and line width is used to set the drawn graph Byblock; Non-by block refers to the color, style, and line width is used to explicitly set the drawn graph block.

After inserting the Bylayer blocks, tiles in the object's color, line style and line width andFigure block after inserting each layer's object is located, that is, set the layer color, layer styles and layer line width, instead of with the tile after inserting the layer objects on the current setting, i.e. the current color, the current line style and line the current line width. That is, before the block insertion Bylayer, if you are inserting graphics file has the same name as the layer of the tile, block after inserting, Bylayer tiles corresponding layer object's color, line style and line width will follow is inserted graphics file of the same name in the tile layer settings. At this point, if the tile layer sets and inserted graphic files with the same name as the tile layer settings are different, in the tile insert before and after the tiles color, line style and line width changes significantly. If you are inserting graphics file does not have the same name as the layer of the tile, block after inserting, Bylayer tiles corresponding layer object's color, line style and line width remains unchanged. Bylayer block decomposition, tile all object's color, line style and line width remains unchanged. Bylayer block after inserting, figure blocks object's color, line style and line width three conditional change.

After inserting the Byblock block, all objects in the block diagram of color, line style and line width with the current settings of the insertion layer (the current color, line style and line width). Although the figure block inserted figure block objects generally not in the same layer, but figure block all objects but have the same colors, same style, and the same line width. Byblock block decomposition, tile all objects into Byblock color (white), all objects of type become Byblock type (solid line), but the line width of all object remains in the tile line width when inserting. Byblock block after inserting, figure blocks object's color, line style and line width are unconditionally.

After inserting the Non-by block, all objects in the block diagram of color, line style and line width remains unchanged. Non-by decomposition before and after the tile all object's color, line style and line width remains unchanged. Non-by block tile after inserting, figure blocks object's color, line style and width are unchanged.

If you draw an object in a block, its color, style or line width used are not the same kind of settings, if the color, style or line width using Bylayer setting tile inserted that corresponds to the color, style or line width of the object where the layer of color, style or line width. If the color, style or line width using Byblock setting tile inserted that corresponds to the color, style or line width will be inserted into the current color of the layer, the current line style or the current line width. If the color, style or line width using Non-by setting tile inserted that corresponds to the color, style or line width will maintain the object when drawing color, style or line width unchanged.

In Figure block insert, if on the tile of the color, style or line width is not satisfied with, of course, you can put the figure block decomposition for adjustment, but if you do not break down the tile and direct adjustment blocks of color, style or line width, Byblock Bylayer block, block, block need to distinguish between Non-by.

After inserting the Bylayer blocks, tiles in the object's color, line style and line width, not by "object" toolbar "color" drop-down list box, the "style" drop-down list box and the "LineWidth" drop-down list box to change directly, but you can "Layer Properties Manager" to change the layer's color, style, or to indirectly change the line width. Click on the "objects" toolbar "layer" button, you can open "Layer Properties Manager" window.

After inserting the Byblock block, the block of the object graph of the color, style, and line width, accessible through the "object" toolbar "color" drop-down list box, the "style" drop-down list box and the "LineWidth" drop-down list box to change directly.

After inserting the Non-by blocks, tile without decomposition, tiles in the object's color, line style and line width is not likely to change, either through the "object" toolbar "color" drop-down list box, the "style" drop-down list box and the "LineWidth" drop-down list box, or directly in the Layer Properties Manager "by changing the layer color, style or line width indirectly changed.

If you draw an object in a block, its color, style or line width used are not the same kind of settings, if the color, style or line width setting using Bylayer, tile inserted that corresponds to the color, style or line width can indirectly change; if the color, style or line width using Byblock setting tile inserted that corresponds to the color, style or line width can be changed; if the color, style or line width using Non-by setting tile inserted that corresponds to the color, style or line width can no longer change.


Third, when drawing the tile suggestions

According to the above on the tile composition object layers, color, line style and line width change analysis, draw the following conclusions.

To make the tiles into the object after the tile layer with the Insert layer of the tile, tile the object's color, line style and line width with tile insert layers in a layer set to Bylayer 0 layer with color, line style and Bylayer Bylayer line width system block, i.e. 0 layer block insert on Bylaye, its tiles each object resides layer will transform to insert layer of the tile, tile the object's color, line style and line width will figure block insert layers in the layer settings.

To make the tiles into the object after the tile layer with the Insert layer of the tile, tile the object's color, line style and line width with the tiles into the layer of the current settings, use the level 0 Byblock color, Byblock line style and line width system block Byblock, i.e. 0 layer Byblock block insertion, the figure block the object layer which will change as the Insert layer of the tile, tile the object's color, line style and line width will insert a layer with layer blocks the current setting of a.

To make the tiles into the object after the tile layer, color, line style and width are unchanged, in non-0 on a layer with an explicit color, explicit style and explicit line width system block.

In order to better organize and manage graphics, generally a layer using a color, so hope Gallery in the tile all objects are anchored to the insertion of the tile layer, tile all object's color to a layer with the layer color or the current color, tile all objects of type and line width does not change, then, should be 0 layer with the color or colors Byblock Bylayer, explicit line style and line width with explicit to draw segments.
