Thanks for sharing.
Ah, .DXF! One of my favorite and most hated formats. I helped design the extensive DXF upgrades for AutoCAD R14 while I was AutoCAD Program Manager at Autodesk. The nice thing is that it often works and the difficult thing is that DXF is not very human-readable.
Anyway, you made me look for an available, free online open source DXF viewer. I am having trouble locating one. ;-(
The best I could do was sharecad but it is not open source.
And Autodesk Viewer - built on Three.js like my viewers - is also not open source
As as is usual, produces interesting results.
Perhaps some day - in another thread - we could discuss the need for a Spider DXF Viewer.
I think you last two message begin to raise an important issue. There is a definite gaps in what this and the other Spider viewers can do and could do. With the Spider gbXML viewers, I have never included the display of “RectangularGeometry”. Personally, building tools for their display would be a nice challenge. But nobody has ever asked for this and this geometry appears never to have been used and any of the generally analysis programs (as far as has been reported to me). So I have never built such a viewer.
If you can think of a good reason - with reasonable degree of priority - for adding Simple geometry, then I will have a go. Never forget that I am but a humble architect and that the renderings are more important to me than the as-built. ;-))
