A friend of mine kindly drew out to EM scale track plan of Eardisley station in Autocad. When I imported the dxf file into Templot it was the right scale but something weird happend to the file when it was imported as can be seen in the Eardisley JPG when in fact it should looked like 3.JPG. It has also placed it a long way away from the track template 1.JPG and produce some separate shapes located in the bottom right hand corner 2.JPG. Any idea what might be causing this to happen. 3704_011607_460000000.jpg  1.JPG3704_011609_360000000.png  2.JPG 3704_011610_150000000.png  3.JPG 3704_011610_530000000.png  Eardisley.JPG |

Hi Thomas, Welcome to Templot Club.  Please could you post your DXF file (.dxf) as an attachment? It's difficult to see what's happening from your screenshots. The attachment button is below the post editor panel. cheers, Martin. |

Hi Martin Templot BG. dxf was the one that I imported into Templot and gave the odd results. I also tried cropping the dxf file that gave me Station4 dxf and when I loaded that one into Templot that was fine but it still added the exta bits at the bottom right hand corner. |

Hi Martin Templot would not allow me to attach more than one dxf file so here is the other one. Thanks. |

Hi Thomas, Thanks for posting the files. That was a strange DXF. Someone had got their decimal points out of position -- I doubt that you wanted it 50 metres and 25 metres from the grid origin? I moved it to 5 metres and 2.5 metres: 2_012349_200000000.png  Also the track gauge was drawn at 20mm instead of 18.2mm for EM. Generally when creating a DXF for Templot it is better to draw only the track centre-lines. The items in the bottom corner were labelled as "cassettes", but didn't suffer the decimal point error so stayed where they were. I removed them -- easily recreated in Templot if needed. At the right-hand end there was a severe dog-leg in the curve, causing Templot to draw the arc in the wrong direction. I have replaced it with a smooth transition curve. Below is the BGS3 file to open directly in the background shapes. Also the modified DXF file if you need it. All that having been said, this isn't really the best way to use Templot. There are over 9,000 imported background shapes, making screen response very slow when working over them. And being a CAD design, it has a "set-track" geometrical look. Most Templot users would use a map as a guide for track planning. Templot can capture historic maps from the internet and display them at the correct scale as a background guide. If you are modelling Eardisley to scale, a 25"/mile map can be captured from the NLS web site: 2_020018_530000000.png  It is easy to shrink the map lengthwise if needed, and there is also a function to wrap a map onto a curve to fit a railway room. Here is the URL for the map: http://maps.nls.uk/geo/explore/#zoom=18&lat=52.13170&lon=-3.00704&layers=168&b=1 The function to import it is at background > maps menu item. Here is the BGS3 file below (it will be very slow to load with so many shapes), DXF to follow. cheers, Martin. |

Hi Martin You have been most helpful indeed and the service you provide is excellent. Although I paid for a copy of Templot many years ago I thought it proper to make a donation towards your generosity in providing this excellent software to modellers like myself. Keep up the good work. Tom |
