Warning: Before creating the survey control file, confirm that all steps have been followed in Create survey control file from field survey to ensure that only primary control information is included.
  1. Open drawing file < Project_ID >\base\SurvCtrl.dwg

    1. Export to LandXML dialog box
      1. Click on the Uncheck All button
      2. Place a check mark in the box next to Point Groups
      3. LandXML version: 1.2

Civil 3D exports 3D breaklines when exporting surfaces to LandXML. This makes existing LandXML surface files significantly larger. Only the existing surface triangles are needed to define the existing surface when imported in other software programs. All the proposed design breaklines provided to the contractor are only to be in the breakline.dwg file.

The following workflow produces LandXML files for existing and proposed surfaces that contain only point and face data.

Create a temporary DWG file

  1. Application menu icon > New
    1. Select C:\WisDOT\Stnd\C3D20XX\Templates\Begin-dwg\design-start.dwt
    2. Open
    3. You do NOT need to save this file.
  2. Data reference all required surfaces for the Construction Data Packet. See WisDOT-C3D-ConstDataPack-Meta.docx for Construction Data Packet requirements.

Export the LandXML file

  1. Output tab > Export panel > Export to LandXML
    1. Export to LandXML dialog box
      1. Click on the Uncheck All button
      2. Select the existing surface by placing a check mark in the box next to the surface's name
      3. LandXML version: 1.2
      4. OK
  2. Browse to < Project_ID >\const\CD-BaseData
  3. File name = <Construction_ID>-Srfc-Ex.xml
  4. Save

  5. Repeat steps 1-4 for each design surface utilizing the naming conventions below.

Source Surface File Surface Exported LandXML file
Project ID\BaseData\Surf-Ex.dwg Exist Project ID\const\CD-BaseData\ Construction_ID-Srfc-Ex.xml
Project ID\Design\Surfaces\ Surf-Rfnt-All-Datum.dwg Rfnt-All-Datum Project ID\const\CD-Design\CD-Surface\Construction_ID-Datum-Srfc-Const-Stg.xml
Project ID\Design\Surfaces\ Surf-Rfnt-All-Top.dwg Rfnt-All-Top Project ID\const\CD-Design\CD-Surface\Construction_ID-Top-Srfc-Const-Stg.xml
Project ID\Design\Surfaces\ RuralDwy.dwg Rfnt-All-RuralDwy Project ID\const\CD-Design\CD-Surface\Construction_ID-Top-Srfc-RuralDwy.xml

This file includes all mainline and side road reference line and design profile data for the LET project.

When all project alignments and profiles are in one file

  1. Open drawing file < Project_ID >\dsgn\aliprof\AliProfXX.dwg
  2. Output tab > Export panel > Export to LandXML
    1. Export to LandXML dialog box
      1. Click on the Uncheck All button
      2. Select all the mainline reference alignments and design profiles by placing a check mark in the box(es) next to the name
      3. LandXML version: 1.2
      4. OK
  3. Browse to < Project_ID >\const\CD-Design\CD-AliProf
  4. File name = < Construction_ID >-AliProf-RL.xml
  5. Save

When project alignments and profiles are in multiple files

Create a temporary DWG file

  1. Application menu icon > New
    1. Select C:\WisDOT\Stnd\C3D20XX\Templates\Begin-dwg\design-start.dwt
    2. Open
    3. You do NOT need to save this file.
  2. Data reference all required alignments and profiles for the Construction Data Packet. See WisDOT-C3D-ConstDataPack-Meta.docx for Construction Data Packet requirements.

Export the LandXML file

  1. Output tab > Export panel > Export to LandXML
    1. Export to LandXML dialog box
      1. Select all the alignments and profiles by placing a check mark in the box next to the Alignment heading
      2. LandXML version: 1.2
      3. OK
  2. Browse to < Project_ID >\const\CD-Design\CD-AliProf
  3. File name = < Construction_ID >-AliProf-RL.xml
  4. Save

Requirement: File includes the mainline and side road edge line alignments and design profiles used in the design of the project that are also included in the LET plan. Design alignments that do not have a corresponding profile should also be included.

Profile examples: curb return profiles, intersection islands
  1. Open drawing file < Project_ID >\dsgn\edgeline\Pavt.dwg
  2. Data reference any design edgeline profiles that are included in the LET plan
    1. Data shortcuts may need to be created in the source dwg if this has not already been done.
  3. Output tab > Export panel > Export to LandXML
    1. Export to LandXML dialog box
      1. Click on the Uncheck All button
      2. Select all the edge line alignments and design profiles by placing a check mark in the box(es) next to the edge line alignment's name and profile name.
      3. LandXML version: 1.2
      4. OK
  4. Browse to < Project_ID >\const\CD-Design\CD-AliProf
  5. File name = < Construction_ID >-AliProf-Pavt.xml

This category includes points provided in plan detail sheet tables.

Examples include intersection and curb ramp details.

Other design points shown in the plan that are not in a table may be provided as well but are not required. Projects completed in Civil 3D 2019 and earlier are excluded from this requirement.

Tip: Multiple files may be exported in order to separate design point data by location.

Option 1 - Exporting drainage structure data when used as design layout points

To use this option, design point information was created using dynamic pipe network drainage structures. See the Curb ramp detail sheet workflow for more details.

Refer to the training documentation Data for Construction - Structures To Point LandXML to export point data.

Option 2 - Exporting COGO points

To use this option, design point information was created using static COGO points.

    1. Export to LandXML dialog box
      1. Click on the Uncheck All button
      2. Select the applicable point group(s) by placing a check mark in the box next to the point group's name
