Hi crew
I have a dilemma. I have a client that has given me dimensions of his room but it’s of an irregular shape. The floor is level, so is the ceiling but the walls all go off at different angles from each corner. There are 4 corners with one being the only 90 degrees.
I don’t mind so much eyeballing this but it’s proving really difficult to come close to his pictures. The lines want to stretch and pull against one another and there doesn’t seem to be a way to restrict them from stretching and rather hinge from each connecting point if that makes sense? It would make things so much easier if they would.
Is there a much easier method to getting something relatively close without me pulling my hair out?
Do you not have the dims (including, ideally, diagonals)?
The first thing you should consider is how the model will be used.
In existing buildings it is quite common that few things are exactly plumb or square. Carpenters and installers are accustomed to dealing with these flaws via shims, fillers, scribes, trimming, etc. If you are intending to show a plan for new cabinets or other furnishings, a model that is close is probably good enough.
Since you know that one corner is 90 degrees, you could draw the two walls from that corner and then swing arcs from their ends to find the fourth corner. To avoid imprecision due to SketchUp’s representation of circles and arcs using segments, you can either increase the number of segments until the error is acceptably small or you can use an extension that finds circle intersections exactly, such as my own Circle Intersect, or TIG’s True Tangents (both available on SketchUcation).

With 4 sides, you need the four length and one angle or 3 side and 2 angles.
You wrote that you have one 90° angle. You only need to measure the 4 sides and you are good to go.
Draw the 2 edges that define the 90° angle and, with the other 2 sides known, you can triangulate the corner opposite of the 90° one.
