I like that it is easy to use with many options available, as well as being able to add your own custom components if needed! It has been difficult at times trying find things in certain areas of software (such as how easily you can change component dimensions).
There are some features/components missing from this version compared to previous versions which could be helpful but overall we have very little issues working within Elcad using our PTC products such as Pro Engineer or Power Plant Designer Software Suite - so far nothing major!! We do not work directly with any other companies aside form power plants manufacturers when dealing wtih cad files / drawings etc..
