Format, contents and file naming convention at the milestone submittals shall be in accordance with [[Chapter_3_-_Standard_Naming_Conventions|Chapter 3]].  Also see [//{{SERVERNAME}}/images_design/8/8c/RID_Review_Checklist.xlsm RID Review Checklist.xlsm] which is outlined in [[Chapter_6_-_3D_Model_QA/QC#6.1_Design_Model_Quality_Control|Section 6.1]].

The Development Guide has moved to a Sharepoint site.  
  
−
These files must be turned in at all submittals. They can be referenced to the other files specified in this section for milestone submittals if necessary and merged into the final RID files as indicated in [[Chapter_5_-_RID_Process|Chapter 5]]. The files listed below not specifically defined in [[Chapter_3_-_Standard_Naming_Conventions|Chapter 3]], should use the Miscellaneous (Z) designation.

* Alignment File(s):
 
−
** Option 1: Can contain all the project alignments. Only one scale is allowed for this file. In the [[Chapter_2_-_Data_Requirements#2.2.2_MDOT_Road_Design_Software_Requirements|MDOT_02]] workspace all alignments must be created with Civil Geometry and utilize a geometry feature style that auto exports to the GPK. It is referenced to the corridor file(s) for use with modeling.
 
−
** Option 2: The RID required geometry can be annotated from the COGO horizontal alignment chains using the Design and Computation Manager (DDB). These can have multiple DGN models for various scales as needed for the plans during design. When using the [[Chapter_2_-_Data_Requirements#2.2.2_MDOT_Road_Design_Software_Requirements|MDOT_02]] workspace actual Civil Geometry alignments auto exported to COGO would be stored in the corridor files or referenced from another design alignment (base) DGN file which must be submitted with the corridor files.
 
−
 
 
−
* Corridor File(s) – ([[Chapter_2_-_Data_Requirements#2.2.2_MDOT_Road_Design_Software_Requirements|MDOT_02]] only) Contain one Roadway model. One corridor file is needed per roadway longer than 200’ in length. (Not including the Approach and as specified [//{{SERVERNAME}}/images_design/c/c1/Roadway_3D_Modeling_Recommendations.pdf Roadway 3D Modeling Recommendations.pdf])
 
−
 
 
−
* Superelevation File(s) – ([[Chapter_2_-_Data_Requirements#2.2.2_MDOT_Road_Design_Software_Requirements|MDOT_02]] only) Can contain all superelevation sections and lanes or can be broken out to match the corridor file limits. Typically referenced to the corridor file.
 
−
* Civil Cell File(s)- ([[Chapter_2_-_Data_Requirements#2.2.2_MDOT_Road_Design_Software_Requirements|MDOT_02]] only) Can contain all civil cells for an entire project, broken out by roadway, type or whatever is need to accommodate the project needs. Civil cells should not be placed in the Corridor files, the exception could be intersections when ditches are needed to flow around a quadrant and continue beyond the civil cell limits.
 
−
 
 
−
* Component File(s) – ([[Chapter_2_-_Data_Requirements#2.2.2_MDOT_Road_Design_Software_Requirements|MDOT_01]] only) Contain the 3D components from Roadway Designer for the entire project or broken out by roadway.
