dgn to dwg conversion

Hi @tlabs

as @pratap mentioned, ideally you need to have a template file with all your block definitions. To create a template, you can

• read your source dgn-file(s) with Expand Named Cells checked to expand cells into elements and Preserve Named Cell Insert Points unchecked to avoid reading cell insert points as features;
• filter one instance of each cell (using igds_cell_name and igds_cell_insertion_x/y/z attribute values);
• aggregate all elements belonging to the same cell (using igds_cell_name as Group By attribute);
• name the aggregate (future block) by adding autocad_block_name attribute and setting its value to igds_cell_name;
• write the named aggregates into template dwg-file.

When you will be processing your source data, please uncheck Expand Named Cells in Bentley MicroStation Design Parameters (Reader parameters) dialog to read cells as points and use your template dwg-file for writing (see Writer parameters).

Please take a look at https://knowledge.safe.com/questions/25231/cells-to-blocks.html where @DaveAtSafe explains a more advanced block definition scenario.

The following article and example workspace may be useful when creating a template file: https://knowledge.safe.com/articles/1178/microstation-cells-to-autocad-blocks.html
