Add High/Low Points

Icon:

Introduction

Places COGO Points at string point locations in a model.

This command allows users to mark specific points (high points, low points, or all points) with blocks based on the sampling of selected codes from the model.

Usage Workflow

1. Select Model: Open the form and select a model (or "TotalModel") to view available codes.
2. Select Codes: Check the specific codes you wish to include from the list. Multiple codes can be selected and toggling on/off will apply to all highlighted rows.
3. Configure Point Style: Select the Point Style and an optional code set table.
4. Choose Point Types: specific if you want High Points, Low Points, or All Points included.
5. Set Tolerance: Enter the distance tolerance (default: 0.001) to detect low and high points.
6. Assign Code: Enter the code that will be assigned to the placed blocks.
7. Process: Click the "Process" button to generate the blocks.

Best Practices

Use a point code that will not be added to a surface unless required

The fastest way to delete all points within a poin group is to use the Point Groups command button on the form. Highlight all points, click Options > Delete

Use an appropriate tolerance relative to how flat your site is to limit detection of multiple low points.

Test with a single code first before processing complex models.
