1. Open Civil 3D (applicable for 2020 and newer)
   1. Application Menu > New > survey-start.dwt
   2. Application menu > Save As >Enter file name
      1. Standard naming for Existing Mapping topography is M(flightname)-<C3D version>.dwg
      2. Standard naming for topographic files used in plans production is Topo-ex.dwg. This can be a combination of mapping and survey objects, just mapping objects, or just survey objects, depending on project needs.
      3. Civil 3D File Naming Standard: FDM 15-5 Attachment 3.3 CADDS AutoCAD Civil 3D File and Layout Naming Standard

2. WisDOT Survey Tab > Mapping Panel > Insert Mapping File

   1. Select the DWG that was exported from Microstation > Open

   2. The chosen file is inserted into the drawing.
   3. Repeat the command if more files need to be inserted.

The Insert Mapping File tool works to ensure that all blocks and text objects contained in the dwg are properly migrated from the Microstation exported DWG. The remaining topics below are provided as guides if there are things that need to be corrected. In cases where objects need to be corrected, please notify support.cae@dot.wi.gov so the Insert Mapping File tool can be reviewed.

Info: At times, certain blocks that are migrated from DGN to Civil 3D DWG may not convert correctly. This is apparent when reviewing the insert block dialog. Blocks that contain names with "_##" in them are blocks that need to be updated. They also show up as color in the insert block dialog.

1. Add all correct block definitions to the drawing: WisDOT #### Tab > Manage Panel > Add Components > All Components
   1. Repeat this step later on if it appears that a target block to be inserted is missing.
2. Review the Insert Block Dialog Box to find blocks that need to be replaced.
   1. Command Line: InsertEnter
   2. The Insert Dialog Box will open. Scroll through the Current Drawing Tab to find any blocks that need to be replaced, as shown in the image above.
   3. Typically, blocks that end with _## will need replacement.
   4. Best practice is to keep the Block Dialog open while updating blocks. Use the Block Dialog as a reference as to which blocks need to be updated. Once the old blocks are purged from the drawing using Purge command PU or the DOTClean Action Recorder Script, the Block Dialog will update and not show the old blocks. This is recommended to be completed after all blocks are updated.
   5. To see locations of "bad" blocks, use Quick Select to select all instances of the blocks that meet the search criteria applied.
      1. Right Click > Quick Select
      2. Apply to: Entire Drawing
      3. Object Type: Block Reference
      4. Properties: Name
      5. Operator: * Wildcard Match

      6. Value: BlockName_*

         

3. The block replacement command requires the selection of the new block. Begin by placing the target new block that will be replacing the outdated blocks. This can be done anywhere in modelspace.

   1. Only select blocks that appear white and do not have the _## suffix.

      

4. WisDOT #### Tab > Manage Panel > DWG > Replace Blocks
   1. Select the blocks to be replaced
      1. Option 1: Type the Name of the block

         1. At the Command Line type AC_* (Block name without the number suffixes plus a wildcard > XX_*) It is recommend to always include the "_*"when typing the name of a block (ie AC_*), unless you know exactly the name of the block that is needing to be replaced, whereas the complete block name could be entered (ie AC_1).

            

         2. Enter
      2. Option 2: Select a block to be replaced in model space.

         1. After entering the DOTBLKREPLACE command, pick the option Select block to use name

            

         2. Navigate to and select a block to be replaced
            1. The tool will look at the block name and create a filter based on that name. For instance, if the block name is INLT_61, it will automatically select all blocks that meet the wildcard name of INLT_*
   2. Select the block that is the target replacement
      1. Selection must be done in modelspace

      2. This could be a block that is placed using the Insert Dialog Box in step 2, or a block that has already been placed in model space.

         

   3. The blocks will be replaced while maintaining all original properties

      

5. Repeat steps 3 and 4 for all remaining blocks.
   1. Use the Insert Block Dialog Box to determine which blocks to replace.
6. Clean and purge all unused blocks from the drawing.
   1. Command Line: PurgeEnter

      1. In the Purge Dialog Box, ensure all checkboxes are selected.

         
         

   2. Purge All
   3. All unused _## blocks should be removed.
7. Review the Block Palette for any blocks that may contain _## in the name and should be replaced.
