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 Attributesīlocks 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.Ī 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 ‘instance’ of a block definition. A block ‘ Definition’ and a block ‘ Instance’. Unlike groups you cannot change the geometry in one block without changing all the copies of that block.* Block Definitions and InstancesĪutoCAD Blocks have two parts. Unlike AutoCAD’s Groups If you change the geometry that is contained within a block all copies of that block will also update. However, it will disappear after you REGEN the drawing.AutoCAD blocks are a way of collecting geometry together into one object which you can use repeatedly in your drawings. After you finish the hatch command, it will still appear. The annoying thing about it is: it doesn’t disappear immediately. If an area has gap, during hatch creation AutoCAD will give you warning and show you the gap. However, if you want to turn it off, you can click the button below. In AutoCAD 2013 I found that it is turned off by default. However, like the other tools, you probably don’t like it. You can choose the object you want by selecting from the list. And if you click it, you will see a list of overlapping objects. If you move your pointer above overlapping objects, then you will see the symbol.
Selection cycling is a fancier way to do it. Later, we can cycle by holding and pressing. In very old version, we can cycle between object by holding and click the mouse button.
Selection cycling is a feature introduced in AutoCAD 2011. You might create constraints automatically if you turned on infer constraints.Ĭlick the button below if you turned it on by accident. If you see the symbols like above, then your objects have geometric constraints. Geometric constraints might be useful, but not everybody use it yet. However, if you want to hide it anyway, you can set GEOMARKERVISIBILITY to 0.īy the way, the symbol would appear like below if you set visual styles to 2D wireframe. It will not show up when you render the model. However, there’s nothing you should be worry about. I usually set this when I want to render using natural sun light. It will appear only if you defined the geographic location. I don’t remember in which version this symbol is added. If you turned it on accidentally, you can turn it off by clicking annotation monitor at status bar, drafting tools group. And of course, if you don’t turn on annotation monitor. You shouldn’t see the warning if you don’t create 2D drawings from 3D model in AutoCAD.

However, automatically turns on (sets ANNOMONITOR to 2), when a model documentation edit or update event occurs. By default, the variable value is -2.Īnnotation monitor off. When you click the exclamation mark, it will ask you to reassociate or delete the dimension.Īnnotation monitor is controlled by ANNOMONITOR system variable. Annotation monitor will give you warning when AutoCAD can’t maintain your dimension associative. This is the latest feature that shows symbols on AutoCAD drawings. There are several questions that I found frequently asked. It becomes common we find strange symbols and sometimes it doesn’t work as we expected. And sometimes we skip several versions until we use the latest one. Not everyone have time to find out new features in their new AutoCAD software.
