# Virtual Intersections
You can create virtual intersections where the extension lines of disjoint elements intersect for easy positioning during subsequent processing.
How to create：
Method 1: Pre-pick element creation 1)Select two lines by holding down ctrl or by box picking, etc 2)Click the "Draw Points" command or the "Virtual Intersection" command to generate virtual intersections.
Method 2 of 2: Create using the Virtual intersection command 1)Click the Virtual Intersection command in the Draw Points drop-down box 2)Select two lines 3)Click the OK or Apply button to generate virtual intersections.
Method 3 of 3: Create when dimensioning 1)Use the commands for dimensioning with size constraints 2)Normal dimensioning 3)Right click on element A where virtual intersections can be created 4)Click Find Intersections 5)Click another element B to generate A virtual intersection of A and B. 6)Continue annotating
Elements that create virtual intersections：
Sketch lines, model edges, support to select the same/different types of lines to create virtual intersections
- Straight lines, curves can be created on the extension line virtual intersection points.
- When the selected line has multiple intersections, create the virtual intersections closest to the mouse click.
In the sketch, it is supported to pick up elements outside the sketch to create virtual intersections.
The use of virtual intersection points：
Analog sketch drawing points.
Supports adding dimensions, geometric constraints.
Measurements can be made.
Can be picked up in the feature dialog box, such as stretch boss feature picking points as directions, etc.
Special case:
- Cannot be picked up as a profile in the lofting boss feature.
- Sketch array and scale primitives The elements to be array/scaled do not support virtual intersections, scaled primitives' scale points support virtual intersections.
Virtual intersections Style：The display style of virtual intersections can be modified in "System Settings - Document Properties - Virtual intersections".
