You will not find any true curves during working with this software which simplifies our work in it whereas Fusion 360 works with curves-based modeling or it can understand as NURBS-based where NURBS stands for non-uniform rational B-spline but if we think by technical point of view then it is not NURBS-based actually it uses T-splines.

SketchUp is based on polygonal modeling that means it connects vertices by lines from edges and from surface it connects edges to edges.The common thing between both of the software is you can have free trail for understand their user interface and features.

Fusion is free for educational purpose only for limited time period and for having it commercial use you have to pay $395 for one month subscription, $2,590 ($215.83 can pay monthly) for one year subscription and for three year subscription you have to pay $6995($194.31 can pay monthly).

SketchUp is freemium software so it is free for commercial use with basic features but for advance features software you have to pay $119 yearly (SketchUp Shop), $229 yearly (SketchUp Pro), $575 yearly (SketchUp Pro Classic) and $1199 yearly (SketchUp Studio).

As we know both of the software are developed by different organizations for same type of work but there are some features that makes them special in their working.
