Introduction

The aim of this guide is to provide MicroStation and AutoCAD drawing authors with some general guidance on DGN and DWG file creation and technical tips for the quality of hot spotting in order to gain the best results when using the AVEVA Gateway for 2D Data. Drawings that conform to these guidelines will result in better quality hot spotted Gateway outputs and avoid a number of Gateway errors.

The extractors in the Gateway are able to read almost all the data in standard DGN and DWG files, including attributes of cells and reference blocks, to avoid any need to explode them. However, data associated with non-standard objects, such as entities created by proxy extensions to MicroStation and AutoCAD products may not be readable. Once extracted, tags are identified and graphics hotspotted by transformation Patterns 2D and Base Mapping configurations. These functions will be briefly described to provide context to the later sections.
