Is there any way to redefine objects as 100% once you have made them proportionally as desired?
i.e take the "plane" default object and shape to a rectangle x:y ratio and then define that as x=100% and y=100% so that you could size other distorted objects to match its size and proportions?
Also anyway to scale a decal to the size of the surface its mapped too. Create a panel, size it to ratio 2:1 and then import and place a perfect 2:1 ratio graphic to its surface. All measurements seem to be related to the base model and not the scene, distorting decals and making objects match each other for size a random spate of guesswork.
Its an improvement on Felix, but lacks the simple repeated visualisation options of something like Boxshot 3 or 4D where you can, once you have a model, swap in similarly sized decal artwork and quickly re render.
Unfortunately there is no way to set a scaled objects dimensions as it's 100%. This is a great suggestion though! I'd recommend posting ideas on our Feedback Portal as that's where we do idea tracking, voting, and status updates. Adobe Dimension CC Feedback Portal
