The Copy Column Line allows the engineer to copy the design from one column line to other column lines. This can be done on a single, fence, or all basis. In order for the design of one column line to be copied onto another column line, the two column lines must start and end at the same stories.

This command has two parts. When Copy Column Line is issued, the arrow cursor turns into the target cursor so that the engineer can select the column whose design is to be copied. After the “copy from” column line has been selected, the “copy to” column line or column lines are selected. If Copy Column Line > Single was issued, the cursor remains a target and the next column line clicked on will have the design copied to it. If Copy Column Line > Fence was issued, the cursor will change to the rectangle cursor so that a fence selection can be made. All column lines completely encompassed by the rectangle will have the design copied onto it. If Copy Column Line > All was issued, the cursor will return to the arrow and all column lines will have the design copied onto them.

If at any time a column line that has been frozen is selected as a "copy to" column line, an error message will be given stating that the command cannot be completed. In order to copy a design onto a frozen column, the design must be cleared first.
