How are relationships between two or more objects established and defined? How is a hierarchy created for these relationships, so that compound systems of linked objects move in a logical, user-defined manner? To use human anatomy as an example, the main trunk of the body would be defined as Parent, while each extremity such as limbs and head, would be defined as Child to that Parent, and would move if it moved, in a relative position as to maintain its connection point to the Parent. Each limb would be a Parent to its Child segments, and so on.  
Is there a provision for such a feature set in Shapr3D?  
Thank you.

I don’t see a real hierarchy of parts, I don’t see how to take 3D “components” and really move them in relation to other components other than by eye, I don’t see a way to edit a sketch and have the model projected/extruded from that sketch change without deleting the entire extrusion/etc… Is there a v…

> Love the speed of app development, thank you! Please could you spend a bit of dev time to improve the file hierarchy and organisational side of the GUI, as after a couple of years driving the pro version, I have a sprawling collection of header images that cannot be organised into folders, date order, alphabetical order, or any other order and if I open a file to see what it is, it immediately jumps to the top of the list, placing it forever out of chronological order. Also, could you enable f…

This has to do primarily with animating a design. How the parts of a system maintain their relative position over a timeline. Does this functionality exist within Shapr?

Hi,  
We don’t have dynamic constraints at the moment. You can align parts together, but if one of them is moved away, the others will not follow.

Is it on the roadmap? When you say ’ at the moment’, does that mean its not a priority at all? This would be very useful to me, I’ve requested it a few times over the, well, years now…

Hey @jb7,  
I cannot tell you any exact dates or details except that we are already working on the topic.
