Select by Height

Uses

  • Easy selection of geometry based on height or level above the ground; e.g. selection prior to using move or extrude on walls, floors, etc., ...;
  • Checking elements of your model to ensure they are positioned at the same height; e.g. walls, floors and window reveals.

Overview

Select all geometry that matches the height of a pre-selected vertex, edge or polygon. A more advanced version (Select by Height with Options) allows for the selecting of geometry within a range of heights, as well as, selecting all geometry above or below the height of a selected vertex/edge/polygon.

Workflow: Basic

  1. Select one or more mesh item layers
  2. Select a single vertex, edge or polygon
  3. Click “Select by Height”

Options

Use Item Transforms
When selected, heights are calculated and compared in World Space. In most cases you will likely want to leave this option enabled.
Range +
Set the height range above the pre-selected vertex/edge/polygon.
Range -
Set the height range below the pre-selected vertex/edge/polygon.
Height and All Above
Select all geometry that is equal to or above the height of the pre-selected vertex/edge/polygon.
Height and All Above
Select all geometry that is equal to or below the height of the pre-selected vertex/edge/polygon.

Notes

  • Selecting large amounts of geometry can take time in modo as the selections are added to the undo stack. For this reason, when large amounts of geometry have been matched by this command a progress monitor will appear during the selection process. This will enable you to abort the selection process at regular intervals.
  • If your scene contains no item transforms and you are going to select a large amount of geometry, then you can get a small performance increase by switching off the Use Item Transforms option.
