Do you know, that… ?

Symmetrical but have a portion of considerable length. You want to show it in the view of interruption but with symmetry?

It's easy to see how you can get.

1. Method of dimensioning the break lines in the drawing.

You can insert dimensions defining the distance from the outer edge interrupt model. If the values ​​are equal – interruption will be symmetric. Unfortunately limitation is the lack of options to link these values ​​or use of the equation (one dimension equal to the second).

2. View interruption in the model created and activated in the drawing.

This method allows you to create three-dimensional model of interruption in the window. What is important, changing the offset value in the plane of the properties window operation – Retraction is done symetric! However, if you move in the graphics window for arrows – then you can individually control the distance notches.
