Thanks for the link, very nice buildings indeed... Australia has a pretty good architecture usually. On my favorite arch site ( http://www.archdaily.com
) you'll find a lot of good examples. Today, you can almost talk of an "australian style"...
Really? I had no idea. I guess if you live here you kind of get used to it and don't notice.
I have a first draft of a layout for a different sort of house. I call it a "hanging lily pad" because the idea is that you have a central column and all the framework for the house hangs from this central column. Therefore the frame is largely loaded in tension. Where as my "Lily Pad" idea was a platform on top of the central column supported from underneath a bit like the base of an up turned wine glass. The supporting frame of the platform on which the house would be built would be primarily loaded in compression.
Being circular and polygonal, these are, I think, an interesting test case for FreeCAD. I used a sketch to calculate the centre line and length of one of the upper C-beams. I used two sketches for the cross section and angle cut of the beam. Actually this is not truly correct because the cross sections are now not at a right angle to the path so the beam's cross section is actually distorted a little bit.
I repeatedly used Polar Draft Arrays after making the first of most beams.
I have some bugs
1)I used view measure distance from one outer top tip of the perimeter frames array to another of its outer top tips, it worked but when I deleted it it crashed FreeCAD. I have been getting FreeCAD to crash on delete of a "view measure" intermittently for quite a few days now.
2)My horizontal beam and perimeter frames will not fuse. I tried making the horizontal beams longer so that they intersected the outer frames by 10mm at each end, but it still wont make a successful fuse.
3)Sketch 10 insists on being on the xy plain even though I try to attach it to another face of the wall like the Arch window "door".
4) I highlighted and copy paste the three sketches, the sweep from those three sketches and the polar array of the sweep from the group "c_section_light_steel_beam" all at once and moved them into group "c-beams2". The idea was to then modify the path sketch and move the two end sketches so that the sweep and array would then represent the next c-beam 450mm to the right of the outer origin beam. The sketch mod and moves work fine but the copied sweep did not move as it still seems to be described by the original sketches and not the copies. That is a behaviour issue, either correct or not and therefore is possibly not a bug but just a learning curve. But here is the bug, now when I try to delete the copied array FreeCAD crashes. I can delete the copied sweep but not the array. I have copied the fcstd file (I am now working on the_lily_pad_hanger_3.FCStd) so that I could test a work around but still keep the FreeCAD crashing file to help bug squashing. The successful work around is to first change the array from a polar array to a ortho array, then it allowed me to delete it. Here is the file that will crash when you delete array004001 in the last group "c-beams2"
