A new feature of Civil Site Design V26 is the Best Fit Alignment command. This command is available to AutoCAD and BricsCAD users and allows you to create an alignment based on Cogo Point or polyline data.
When the command is run, the Best Fit algorithm analyses the Cogo Points in the specified Point Group or the vertices of the selected Polyline and fits a series of tangents and curves to create a new Alignment that describes these inputs. The user is able to change the radii, curve detection and tolerance of the algorithm to refine the fit to the original data.
How it Works
This command allows you to build a Best Fit Alignment using Cogo points or existing polylines. The command is available from the ribbon:
Alignments >> Design >> Best Fit Alignment
Before generating a Best Fit Alignment from Cogo points, create a point group of the points to use for the alignment creation.

Once the Point Group for the alignment has been defined, run the Best Fit Alignment command and complete the follow:
- Give the alignment a name.
- Choose the Best Fit method: Cogo Points or Polyline.
- Choose the desired Point Group or Polyline.
- Slide the bars left and right to adjust the curve detection and tolerance of the Best Fit algorithm until the optimal fit is achieved.
- Change the minimum and maximum curve radii as needed.
- Select Create/Update Alignment.
Once the Best Fit Alignment has been created, use the Edit Alignment command for further modifications.
In this webinar we demonstrate the best practice for using Model Builder and unpack all the functionality to operate it successfully, using a road and parking bay design.
In Civil Site Design V24.10, the Design Data Form has undergone some ergonomic improvements and seen the addition of a new Design Variation – Offset by Polyline.
In Civil Site Design V24.10, the Model Builder Edit/Trim by Selection & Group forms received an update which can have a significant impact on selecting sections for trimming models.
The DRAINS exchange for Civil Site Design has been established for over 10 years and has provided users with a solution of drafting in the CAD environment, analysing in DRAINS and generating design long sections with the HGL in Civil Site Design. This popular functionality has been a staple for drainage engineers looking to speed up the process of designing and drafting between the applications.
