Hi

Could you help me, how would I add the following attached data to Bricsys V13 to create an airfoil?

    I've just looked at the attachment and the data has not come out as previously formatted. It should be in two columns

    MH 32  8.7%

    1.00000000  0.00000000

    0.99671850  0.00034782

    0.98706463  0.00149967

    etc

    I'll try and attach again!

    Hi Simon,

    Simple way to do this is by converting your data into a ._SCRIPT. A script is basically a list of commands as you would type them in at the command prompt. Your data is already close to the format required by a script, so you could use a text editor to do a search and replace to provide the correct format. For more complex data you can utilise a spreadsheet to get it to the correct format for a script. Having done this you would copy and paste into a text file, then save with the .scr extension.

    To run a script you can either use the ._SCRIPT command, or drag and drop it on your drawing from windows explorer.

    I would put the points into a script too. Or if it's only a one-off, perhaps they could be cut and pasted at the command line (with the spaces replaced with commas. A script will probably accept a new line as a break between points, the command line might want a line space in place of each carriage return).

    I think using them to draw a polyline, since the spline command will ask for a start and finish angle - getting those right is the hardest part of physically drawing any such curve.

    You can p-edit the flats into a curve after it's drawn.
