This app contains over 200 blocks. All you need to draft Building Services like Electrical,Mechanical,HVAC,ELV,etc.
We use these extensively and you do not need anything else to finish a Building Services plan.
Included is also a file called "1 Blocks Booklet" which is a legend of the symbols you will find in this app.
