Could someone give me a bit of help please as I am having a senior moment in trying to add a background shape My club is in the process of building a new layout Belmont on the old Stanmore to Harrow Weald Line. When loading the previous plan I ended up with a miniscule plan which somehow I managed to enlarge. I would line to get the latest hand drawn plan in at the correct size please I open Background shapes, then go to add a shape. I chose scanned model trackplan and this is where I am making a mistake. Its on a sheet of A4 297 mm x 210 mm The 2 boards total 8' long and are 1/9th scale. 255 mm long x 48 mm Please what do I enter in X dimensionY dimensionNo idea of the DPI so entered 150 in both as suggested and 9  for the scale now its come out at about 50 % too wide and what looks like 25% to long Also please how easy is it to move the shape to line it up with the bottom left corner and how to do it please
edit
One thought is to cut the plan from the paper and rescan, would that help in positioning it with the bottom left corner ?

Hi John,

To have the corner of the picture shape on the grid origin in the bottom left corner, set X and Y to zero (0). You will usually want the corner of the baseboards on the grid origin, which means you need to shift the shape afterwards (see 6. below).

Your dimensions are a bit confusing. If you have drawn boards 8ft long as 255mm, the drawing scale is 1 : 9.56

If entering 150dpi has produced incorrect results, obviously that was not the setting on your scanner. You should be able to set the dpi to whatever you want on the scanner preview dialog. I suggest 300dpi is a good setting to use.

If all that is too confusing, it may be easier to scale the image manually. Do this:

1. set the grid lines to 1ft spacing. That's trackpad > trackpad grid options > 1ft spacings menu item.

2. don't forget this. Click  trackpad > trackpad grid options > grid in front of shapes menu item.

3. don't forget this. Click geometry > notch > reset notch on grid origin menu item.*

4. add the picture shape and select the green bar option other map, drawing or diagram.

5. set  X=0,  Y=0,  picture width = your best guess, say 2400 mm.

6. click action > mouse actions: shapes > shift shape menu item.

7. using the mouse, move the image so that the corner of the baseboards (not the corner of the paper) is over the bottom left grid origin lines.

8. it may be a good idea to zoom in while doing this for greater accuracy.

9. zoom out again so that you can see all of the image.

10. click action > mouse actions: shapes > scale shape menu item.

11. using the mouse, adjust the size of the image until it matches the 1ft grid lines.

12. it may be a good idea to zoom in on the top right corner while doing this for greater accuracy.

When you have it right, don't forget to save your background shapes file (.BGS file) before quitting the Templot session.

If all that is too difficult, please attach your scanned image here and I will scale it for you. :)

(*more experienced users may not realise that by default image scaling takes place referenced (locked) to the notch location, which you can move to other locations over the image if you wish. This is useful if you have some existing templates on the trackpad, or multiple overlapped picture shapes. There are other options on the background shapes dialog to lock scaling to the grid -- i.e. to the bottom left corner, or to the spacing-ring instead.)

regards,

Martin.

Thank you very much and when you know how its quite easy, should be out painting the soffits and will do now but here is a quick download, the bridge end is not quite decided on as we have had to make a few compromises. This is a rough and I will need to tidy it up a bit, but that's later
We plan to make a half size card mock up, just to have an idea of what goes where and has it a balanced look.
At the Stanmore end we plan to make a representation of the narrow gauge railway used by the contractors building the housing
The club has had to move premises and are planning to make a quickie layout based about the 30's LMS period. (I hope they will let the odd LNWR loco on) It will be built to 00-sf using the Exactoscale plastic track parts and fastrack bases. The reasoning behind this is the strength given with these components and detail that can be achieved. As it will not have a permanent home and hopefully will go on the exhibition circuit.
We have quite a bit of detail but would like more on both the station buildings and signal box

Hi
This is a separate but vaguely related question. I have with success got a scanned track sketch as my background shape, but when my brain begins to fry I turn Templot off for a rest! When I turn it on again the track comes back, but the background image doesn't. It also doesn't appear in the shapes box until I click on recent files. So I can get it back, but I'd rather it just sat there from the start. Is that possible?

Hi,

Re-save your background shapes with the file name start .

Templot will then load it automatically on startup. :)

regards,

Martin.
