We are often asked how to quickly add multiple blocks into a drawing.
There are a range of tools to share information between drawings, including inserting a drawing as a block (and exploding) or using Autodesk Design Centre (type ADC at the command line). Both of these have benefits and drawbacks if all you want are blocks:
-When you insert a drawing you get everything: layers, blocks, linetypes, Civil 3D styles, text styles, dimension styles, etc. If you only want the blocks, this is a potential problem in getting rid of the extras.
-When you use ADC you can finely control what you move into your current drawing – you can see any open drawing, or select a drawing to use for resource data, then you can select what items from the drawing you want: blocks, dimstyles, layers, layouts, linetypes, text styles, etc. With just about all of these elements you can select multiples, but not blocks. For blocks, you have to drag and drop them individually into the drawing.
An easily forgotten tool is the multiple command, which provides a very efficient method to insert multiple blocks. This command allows for repeated execution of the same command. For inserting blocks:
-Type multiple at the command line, then type insert (command to insert blocks).
-Select the reference drawing containing all the blocks you want.
Every block is inserted into your current drawing, with the same scale and same insertion position. Delete them from the drawing and they’ll still be in the drawing library so you can Insert them from the current drawing whenever you need.
The multiple command can be used to restart any command that normally ‘stops’ at the end of a process, such as the Rectangle command.
