Scaling Length, Beam, Draft from a parent hull form

[Don Schultz]

I am brand new to DS Free. I do not know how to create or manipulate hull forms in DS Free. I have opened files from the “downloads” area of the website, but they are not quite what I need for a known length, draft, beam, and displacement. I can tolerate allowing the hull form coefficients to vary, within a range, but I’d like to “dial-in” my length, draft, beam, and displacement to parent hull forms and see if I like what shows up.

Is there a way to do what I have described in DS Free?

Thanks in advance!

Select “Scale” from the “Tools” tab and then enter your longitudinal, transverse and vertical scale vectors.

Thank you Marven. That works just as you described. I then used the “Hull Transformation” under the “Tools” tab to then adjust to the preferred displacement. This resulted in a modified hull form that was quite fully than I had anticipated, but the process to adjust the hull worked. Thanks again!
