How to Disable Snap to Lines in Syncfusion Angular Diagram for Precise Object Placement

The Syncfusion® Angular Diagram component features Snap to Lines functionality that helps in aligning diagram objects with gridlines during drag-and-drop actions. By default, this snapping behavior is available by injecting the SnappingService providers into your components. However, you can disable it to gain more precise control over the positioning of nodes and connectors, all while keeping the gridlines visible.

To enable smoother movement of diagram objects, you can adjust the snap settings in your diagram configuration by removing the SnapToLines constraint from the SnapConstraints. Here’s how you can do it:

import { DiagramModule, SnapConstraints, SnapSettingsModel, SnappingService } from '@syncfusion/ej2-angular-diagrams';

@Component({
  imports: [DiagramModule],
  providers: [SnappingService],
  selector: 'app-root',
  template: `<ejs-diagram width="100%" height="600px" [snapSettings]="snapSettings"> </ejs-diagram>`,
  standalone: true,
})

export class AppComponent {
  public snapSettings: SnapSettingsModel = {
    constraints: SnapConstraints.All & ~(
      SnapConstraints.SnapToHorizontalLines |
      SnapConstraints.SnapToVerticalLines |
      SnapConstraints.SnapToLines
    ),
  };
}

By adjusting these settings, users experience more flexible and precise interactions with nodes and connectors while maintaining gridlines.
