Drawing - Tim Hof

Drawing is extreamly simalar to lofting but on a way smaller sacle,

we were given three bits of paper stappeled together titled, 7.3M yacht assignment.

this paper told us the lines we needed to draw, the equiwiptment needed, presentaion standard needed and also completion date. there was also on the thrid page, after the second on which it explained the standards was a table of offsets,

we were all told by Murf that these measurmentas were all correct, but i was still unsure of this as the loftings were uncorrect, but he trned out to be correct this one time.

there was one line given which was the LWL. the first steps were to add the sheerlines and deck edges on the proflie and half breath views. these were very easy as you just lookd at the table of offsets and located the station points on the drawing also and just measured off the offsets to transfure to the drawing. on the offset sheet, the letter U stands for Up from the LWL and D stands for Down below the LWL. all the points needed were on the table of offsets but a few were not, this ment we had to transfure measurementes from the station lines to the other drawings, this was quite sucsessful and easy to do.

this was a good section of the course as i enjoy drawing and it was similar to lofting but in a smaller scale which mean you could concentrate easier on areas which need work like lines which were matching up correctly.

there was a table to work out the displacement for the displacment at every station and also the hull center of lateral resistance which in the end worked out the longditude center of boyancy. this was done by seperating the hull from the LWL downwards in Auto CAD. then, sue the polyline tool to seperate the curved line to be able to select the hole shape. then once the hole shape was finally selected, you can group the object by right clicking then clicking yes, or skip this step like I did and just go into the top selection bar to tools, then inqiure then into area then enter then enter, then down in the bottom left corner it says area: then a number, then copy this number and put it into the simpsons diagram in the excell document for every station point. then making sire I have changed the station spacing from .95 to 0.73 which is the distance from station to station. then the document will calculate using the simpsons thery to work out the measurments needed to work out the correct objectives for the longditude center of boyancy.

this was hard to figre out at first but then once you had the added advantage of the use of AutoCAD it was extreamly easy as you needed to know the basic skill of selecting an object and fnding the area, then it was just punching in the numbers and that was that.

The transom development was just like the lofting. the lines were all projected off the transom angle and matched up with a flexy curve to create the transom.
