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.
Bulk earthworks play a key part on many projects and determining the volumes can be a time consuming process. Released in Civil Site Design V23.10, the Subgrade Model Manager (SMM) was developed to assist users with creating subgrade surfaces of any model within the project.
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.
