The Select Similar tool gives users the ability to automatically select objects with similar traits. There are two main ways to activate this tool: select an object and right click, or typing selectsimilar on the command line. The right click method will bring up the right click shortcut menu. Move down the list until you find the select similar option and pick it. According to the filter settings, every object that is similar (in the file) will automatically be selected. This tool can help you select all of the hatch patterns in a few clicks. If you type the command in you will then pick your object to use as a filter, press enter, and away you go. Selecting more than one object will better define what objects you are going to pick, and don’t forget the filters (see figure 1.) You can filter objects according to Color, Layer, Linetype, Linetype Scale, Lineweight, Plot Style, Object Style, and Name. Toggle on or off any combination of these settings that you want to use. The default settings come with Layer and Name as on, all others are off. That means that if I select a hatch object, then all hatch objects on that layer will be selected. If I pick two hatch patterns, each on different layers, then every hatch on both layers will be selected. The more objects you select, the more criteria you add to the filter. But if you pick different object types, a hatch and a region, that are different layers, they won’t overlap. That means that the hatch patterns will have to be on the hatch’s layer and regions have to be on the regions layer.
Most of the filters are self-explanatory. Color selects objects based on their color. If they are set to bylayer, then only bylayer objects will be selected. Object style applies to obejcts that have styles, like text or dimensions. To gain access to the filter list, type SELECTSIMILAR on the command line. You then have the option to select your filter object, or to type SE to get to the settings. A window will open up where you can pick the filters you want to use.
Figure 1: The Select Similar Settings window allows you to set the automatic selection filters that you want to use.
Selection Cycling
Many times in AutoCAD we need to pick through objects that are literally stacked on top of each other. This can make getting the right object difficult. Pressing the SHIFT+SPACE keys on the keyboard will highlight and toggle through the objects near your crosshairs, but now AutoCAD 2011 has an automatic cycling feature. When you pick an object and there are others on it or under it, a list of those objects appears. Scroll through the list until you find the one you need. You can toggle this tool on and off through the status bar. Right click on the Selection Cycling icon on the status bar to get to its settings. Change the location of the Selection Cycling Window, and other formatting features.
Figure 2: Here is the Selection Cycling window showing us what objects there are to choose from.
Object Creation
Another new drafting tool is the Add Selected tool. This new tool allows you to create new objects based on a selected object that is already in your file. To start the command, select an object, then right click. In the right click menu, pick the Add Selected option. If you pick a line, then the line command starts. If you pick a circle, the circle command starts. The new object will also take on the characteristics of the selected object. It will be drawn on the same layer, with the same color and linetype settings as the selected object regardless of the current settings in your drawing. If you are working on a layer called EXISTING SIDEWALK and you see that you need a quick line on the NEW ROOF layer, pick a line on that layer and AutoCAD will temporarily make the NEW ROOF layer active and start the line command for you. When the command is finished, your settings go back to the way they were. This command can help you get small things done even more quickly.
Action Recorder
The Action Recorder was introduced in AutoCAD 2009. It is a great tool that allows you to create macros to help you get a series of steps done, again and again. AutoCAD 2011 now allows you to add or remove user messages for view change operations. It also displays a list of the most recent macros you have used above a separation bar while showing all available macros below. This is handy if you use certain macros often. It’s a small thing, but it is useful. It works similarly to the file lists in the application menu.
Transparency
AutoCAD added a new object property called Transparency. It is a setting that allows you to make an object or objects translucent, or see through. It can be assigned to objects or layers just like color and linetype are. The new property has been added to the Layer Manager and its value can be assigned to layers and controlled through Viewport transparency, just like View Port Color or linetypes are assigned.
The default value for an object is Zero, for no transparency. The value spans from zero to 90. You cannot make an object 100% transparent, only up to 90% transparent. Each value for the setting is a percent. Zero percent means it has no see through (or transparency) traits at all.
Figure 3: the layer manager can control the transparency settings of your objects. Transparency can also be set per object.
Conclusion
There are many valuable new tools and updates in AutoCAD 2011. We have only gotten through about a third of them. There are many new documentation tools that have been added as well as several high end 3D Modeling tools. We will continue this look at the new features over the next few articles.
