... really". I remember before the sketchboard was introduced, suggesting that buildings and other structures could be represented as shoved bonus timbers. It was laughed at as a serious suggestion, but it actually worked very well. And for items such as a cattle dock or engine shed, it had the advantage that they moved with the track if it was modified or repositioned. Using dummy templates for curved baseboard edges is an established method, and there is even an option to display them in the same style as the background shapes: 2_130853_390000000.png which can get confusing if you forget that they are not actually in the BGS file. p.s. Templot works to 80-bit (10-byte) extended precision for the track design. That's how straight track can be represented as a radius of 62 miles (in the model) and still work in the curve calculations. The sketchboard engine uses 32-bit precision. cheers, Martin. posted: 14 Feb 2018 22:28 from: Tony W Tony W wrote: Hi Martin. The background shapes may ...
