It is easy to use, you can easily see your work progress from beginning until now with this software tool. I like it because of its simplicity in usage as well as having an excellent result when used for measurements purposes. Also there are many benefits that come along such things which i have never seen before while using other tools including 3d printing ones. Although simactive corrlator has some bugs but overall no complain at all since we managed them so far by contacting their support team or through live chat feature available on their website. We manage our project plans perfectly with it.
