Start a new drawing using the BSI.dwg template.
Ensure the sheet size is correct by right clicking on Sheet 1 and selecting Edit Sheet. The size should be A3.
The default border is ugly and has too much going on. Delete it from the sheet by finding it in the modelling tree, right clicking on it and deleting it.
In the modelling tree, right click on Borders and Define New Border.
Draw a new rectangle border.
Dimension the rectangle 10mm from the page corners.
Finish the sketch and save the border as plain_10mm_border.
Use the border by right clicking on it in the modelling tree and selecting insert.
All drawings should be created using Third Angle Projection. We need to add a Third Angle Projection symbol to our drawing.
In the model tree, right click on Sketch Symbols and select Define New Symbol.
Draw the below Third Angle Projection symbol and save it as third_angle_projection_symbol.
To get the correct line type for the centre line, first draw the lines and then right click on them, select properties and then change line type to Chain line
To reuse this in other drawings, you can save it to your Sketch Symbols library. Right click on it and select Save to symbol library. Create a new library if you need to.
Use the symbol in your drawing where needed by right clicking on it and selecting Insert.
To change the size of it, you can double click on the symbol and change the Scale value - 0.75 will make it smaller, 1.25 will make it bigger.
The default title blocks are terrible. Create a new title block by right clicking Title Blocks in the model tree and Define New Title Block.
Draw a title block similar to the one below.
The text size used here is 3.5mm
British Standard conventions and line types should be used on all drawings.

Inventor defaults to First Angle Projection. We need to edit the style for the drawing before going further.
Go to Manage, then Styles Editor.
Then Default Standard (BSI) > View Preferences
Select Third Angle
Set your view labels (ELEVATION, END ELEVATION, PLAN) to be below the view.
In the Display box, remove the bit that says (<SCALE>)
You now need to export your template and save it somewhere you can reuse.
Go to File > Save As > Save Copy as Template
Save your drawing template in the Metric templates folder.
Give it a sensible name so you can easily find it again when you need it.
