Clash Sectioning

Turn on Section Clash

Clash sectioning cuts the 3D view down to a box around the clash you select in Pulse Check, so the surrounding model doesn't get in the way.

1. 1

   Open Pulse Check

   See Pulse Check Clash Review if you haven't used it before.

2. 2

   Switch on Section Clash

   The switch is in the Display Settings panel on the right edge of the Results pane. If a clash is already selected, it's sectioned straight away.

3. 3

   Click through your results

   Each clash or group you select gets its own section. For a group, the box covers every clash in it.

Pulse Check remembers whether Section Clash is on the next time you open it.

Where the section goes

The section is a box with six sides, lined up with the model's axes:

• Sides: the clash's extent plus the side buffer in every direction.
• Bottom: the slab buffer below the level at or under the clash.
• Top: the slab buffer below the next level up.

The section never cuts into the clash itself. Where there's no level above or below, that face sits the side buffer away from the clash. Levels come from the Level Grid System chosen in the Clash Tests pane; with no levels at all, the top and bottom also use the side buffer.

Side and slab buffers

A level elevation usually sits at finished floor, so the structure hangs below it. The slab buffer stands in for that slab depth: about 1 ft for a typical slab, nearer 2.5 ft for a precast double-tee deck.

Both buffers are always entered in feet. BIMPulse converts them for metric models. Save the Navisworks file to keep the slab buffer.

Adjust the section with handles

While a section is active, a purple box outlines it, with a round handle in the middle of each face. Handles show through the model, so you can always reach them.

• Hover over a handle to highlight it, then drag it with the left mouse button to move that face.
• The right and middle mouse buttons still work as usual in Navisworks, so you can orbit and pan between drags.
• If a face won't move, you're looking at it edge-on. Rotate the view a little and try again.
• The box can't be dragged inside out.

Your adjustments last until you select another clash, change the side buffer, or turn Section Clash off and on again.

Clearing the section

BIMPulse remembers how your view was clipped before it started sectioning, and puts that back:

• Deselect the clash: your own clipping returns, and Section Clash stays on for the next selection.
• Turn Section Clash off or close Pulse Check: the section is removed and your own clipping returns.
• Save the file: your own clipping is put back before saving, so the section isn't saved into the file. Section Clash stays on, and your next selection is sectioned again.

Sections and saved viewpoints

• With Zoom Clash on, selecting a clash that has a saved viewpoint opens that viewpoint first, then applies the section on top.
• Save Viewpoint in the Results pane saves the current view, clipping included. If a section is active when you save, it's stored in that clash's viewpoint.

Limits

• A group whose clashes span several levels gets a box tall enough to cover all of them.
• One slab buffer applies to the whole file, so it can't match every slab type in a building.
• Two levels set close together give a very short section.
