Controlling and changing Grid Line display

Victor Martinez , BIM Manager from HOK NYC said “While working on a recent project, the need to show column grid lines differently between composite plans and finish plans was requested. In order to accomplish this, the following method was used.”

In this first image, the composite plan is showing the grid lines with the project default settings:

Select a grid line and view it’s properties.

From the Type properties window, there are a few options to adjust how column grid lines are being generated. You are able to change the center and end segments here as well as the symbols being used. For this example, change the center segment to none:

clip_image003

Your plan will now look like this:

clip_image004

After changing the center segment, select a grid line and use the blue grips to drag each end segment to the center which will turn the grid lines back into a continuous centerline in the composite plan view.

Do this for each grid line in the view:

clip_image005

After dragging each grid line in the one view, the grids will now display differently in this view as compared to the rest of the other views:

clip_image006

You can then select the grid lines in the view you changed them in and propagate extents to the remaining corresponding views:

clip_image008

Once you Propagate Extents, you will now have the ability to control gridlines differently in multiple views:

Rotating Callouts

This tip comes from Victor Martinez of the HOK New York Office.

A callout has been placed in a view that appears to run parallel with the angle of a wing of a building, but you aren’t sure. A decision has been made to rotate the callout back to a default 0 degrees. Since there is no way of getting the angle or the rotation of the callout from its instance properties, how can it be rotated accurately back to a default 0 degrees?

By placing a scope box (blue dashed line in below image) in the view you can name the scope box and then assign the callout to the scope box so the callout assumes the angle/placement of the scope box (assuming the default value of a scope box is 0 degrees of course):

Callout Instance Properties:

The result is the callout assumes the scopebox angle:

The scopebox can then be deleted without affecting the callout. Now the callout can be rotated accurately if desired.
