Lining up the outside flange of columns and keeping them in line ..

When modelling portal frames for example and you want the flanges of the columns to line up regardless of the column size or if the column size changes.
The trick is to use a reference plane and lock the flange of the column to this reference plane.

Let me try and explain.

Put in a reference plane, say, 160 off of grid ( the trick is to PIN the reference plane in place ) and then place your column and align and lock the flange to the reference plane.

Now if you change the size of the column the flange will stay aligned and locked to the reference plane.

We now have a Slimflor Beam Family ...

Which can be found in \MasterDocs\CAD\Revit\Waterman Library\Families\Steel and is called W_FRA_SFB.rfa

While we are on the subject of Section Marks ....

To get a "jogged" Section Mark. Selecting the Section Mark makes the Split Segment button wake up.Pick Split Segment then select the Section Mark. you can then drag one part of the Section Mark around.

Revit Stucture !!! You sure ??

Yes. All done in Revit Structure.
Thanks to Nick Stokes for sharing.

Section Marks can at times be quite over powering ...

One way to trim them down a bit so that they don't cover up to much of your drawing.

Just click on the break in the middle of the section mark. You can then also grab the drag points to make the section marks lines even smaller.
