I am wondering about what is the best way to go about developing a Fusion 360 model for a chair in which almost all of its components are not parallel to any of the 3d coordinate system axes?
The following is an illustration of an actual chair:
The rear legs are the easiest aspect since at least their outside face is vertical.
My efforts/ progress to date is illustrated:
As can be seen, I have selected the origin as being symmetrically between the sides at the rear of the chair corresponding to the height of the top of the short vertical flat parts at the front of those rear legs.
Those flat parts are vertical although those planes are an angle to the coordinate system when viewed from above.
The rest of the chair is characterised by everything being at a angle to everything else!
No spline curves are involved, apart from, perhaps, for the backrest.
The design is from an article in a book which provides front, side and top views, together with some detail views (which are also from the front, side and top perspective).
Two examples are provided:
Please appreciate that the actual sides of the seat (as seen in a top view) are not parallel to that side view.
The seat is shown as being horizontal but I should like to generalise the design such that the seat could be at a small angle to the horizontal.
My objective is a parametric design in which all points are determined by numbers in the parameters table.
The coordinates of each point are, in principle, available and can be deduced from provided measurements (lengths or angles).
In many cases the numbers are not provided, but could be deduced from canvasses.
Obviously, one approach would be to draw lines in 3d sketches based on deducing the start and end points for each line.
Those lines could then be projected on the Cartesian planes to check against the canvasses of the front, side, top and detail views.
Inevitably discrepancies would be found with the need to adjust the coordinates of the lines - so this process is likely to become very messy and time consuming!
I am wondering if there is any facility in Fusion 360 to reverse the process,
i.e., based on front, side and top views, can the required 3d lines be generated from some sort of "reverse projection"?
Alternatively, is there an app that could generate the 3d lines from a list of their coordinates?
I am aware of the app for generating 3d splines in such a way - is there a similar app for 3d straight lines?
However, I am doubtful that, even if such an app is available, it would provide a workable solution.
I used the 3d spline app in another design and found that whilst it does it great job of generating curves, it was troublesome to subsequently modify the points/ relate them to parameters which will change.
All ideas as to what is the best approach/ recommended workflow for generating a Fusion 360 model for such a chair will be welcomed and much appreciated!
