Import styles in Civil 2010

To import all styles from one drawing or template to another in 2010, simple create a new point style. Select the marker tab, check Use AutoCAD BLOCK symbol for marker, right click in block area and select browse. Set dwt or dwg at the bottom and select source. Click ok and all styles are imported to the drawing. The only difference is this does not override existing styles that already exist in the drawing.

Rename Blocks and other stuff

before copying a block(s) with duplicate name use the "ren" command to rename all the blocks, if applicable you can use the "Rename to" to add a prefix on multiple blocks.
example:
existing block name "TREE1"
rename to "9-12-01_*"
this will create the new block name as "9-12-01_TREE1"

If the wildcard is used you can rename all the blocks and preserve the original name.
