Hello & welcome,
Today I’ll present another set of usefull tools incorporated into a plugin called Edge Tools but in detail I will present only two of them.
You can download the plugin registering at SketchUcation from here.
First tool allow you to split faces into multiple peaces with parallel lines.
You can use the array commands with that tool.
The second tool I also use a lot erases stray edges.
This are great useful tools which can help you to do things much quicker.
Have a good lack with them.
