Create Visual Group with Selection.ajs

// 
// Author: Ed Tobin
// Purpose: Create Visual Group with Selection
// Requires: jArchi - https://www.archimatetool.com/blog/2018/07/02/jarchi/
// Date: 14 April 2023
//
// WARNING: drops visual relationships between selected objects

// configure defaults:
// the size of padding around the selected elements
// default name for the group
// default border style

padding = 30;
defname = "group";
defborder = BORDER.RECTANGLE; // BORDER.TABBED

minY = null;
minX = null;
maxY = null;
maxX = null;

var view = $(selection).first().view;


// Determine the corner coordinates around the selected elements

    lX = element.bounds.x;
    lY = element.bounds.y;
    mX = lX + element.bounds.width;

// calculate bounding box for group
boxX = minX - padding;
boxY = minY - padding;
boxWidth = (maxX - minX) + (2 * padding);

// create visual group on diagram
var bbGroup = view.createObject("diagram-model-group",

// Nest selection inside newly created group (diagram-model-group)
