Looking for a tool similar to a preview shown in an Ubisoft title.

I am very new to UE4 and the forum, so thank you in advance for your patience.
I am looking for a building editor similar to what has been shown in some videos for the Division.
Something where the building can be scaled and snapped to points.
My google searches have not been too helpful. Any help is appreciated. SnowDrop Engine overview with time stamp.

We have something similar on the Marketplace…

Bascially if you have the knowledge “UE4 blueprints” you can develope such a system by your own.

Thank you, that looks very interesting. I will take a look.
