BIMPROPAGATELINEAR is one of the five Propagate flavours. It can be used to copy detailed connections between two or more linear solids. Common examples are column-beam connections or column-slab connections. For a more in-depth explanation of the general principles of Propagate, read this article on Propagate.

Procedure: Propagating a column-beam connection
Consider the following situation of four columns and two beams. Two of the connections have been designed with an and plate and bolts trough the column flanges (1). One connection has been designed with a diagonal member for additional rotational stiffness (2). The last connection has not been designed yet (3).
We can now use Propagate Linear to copy one of the details to the other locations. In this example we will copy connection 2 to all four locations. We will launch BIMPROPAGATELINEAR.
You are prompted: Select linear or planar solids to connect. At least one should be linear.
Select the column and the beam that are connected by the diagonal member, and press Enter.
You are prompted: Select detail objects (solids, block refs or faces) to be included in the connection (optional).
Select the diagonal member and press Enter. A detail volume is created that completely encompasses the diagonal member and parts of the column and beam.
You are prompted: Propagate this 3D detail? [as Block/as Copy/No/Inflate first] <As block>:
You can choose to propagate this detail as a block to keep the file smaller and more manageable, or as a copy. Inflating the detail is not necessary in this case. For more information on inflating, read the article on Propagate. Choosing ‘No’ will exit the command. Press Enter to accept.
BIMPROPAGATELINEAR now scans the entire drawing for similar locations. When this is done, the view is zoomed out to show all possible locations. Every suggestion is highlighted and a widget is displayed:
You are prompted: Choose next action [Apply all/Cancel] <Apply all>:
A green check mark means that this suggestion will be applied when pressing Enter. A question mark means that it will not be applied due to one of several possible reasons. Hovering over the widget will reveal more information. In this case it says “Existing details detected. Suggestion will not be applied. Click to change.” We want to replace the bolted connection by this diagonal member, so we click both the blue widgets so they turn into green check marks.
If we now press Enter, all connections should be replaced by the diagonal member.
