those reference planes are genius!!

Very nice work! Thanks for the post.

Excellent post, thanks!

Nice job with SolidWorks. I'll have to give CAD another try. I'm worried that some day SnoCad-x may stop working because of Windows or java upgrades.

Love the flames on the skis! Is that cotton material? I made some like that, they really turned heads.

Yes, exact same fabric that you used on Section 8 - 3rd pair, posted Jan 11, 2010.

great job i had not thought of using planes to define those points on the sketch. i was just setting the points at tip, tail and waist to be horizontal in respect to the other side. it was working well but your way seems much more logical

I have my parameters down in 2d sketches...one sketch for shape, one for flex, one for curve shape...

How do you convert these 2D sketches into the 3D sketch like you have modeled Shif? Little help?

are u trying to make the sketch a 3d object or just extrude it so you have a ski.

i would recomend that u extrude your profile along the x axis then cut your side cut down through the extrusion

Composite curves.

For skis in solidworks I just do everything in 2D. Unless you want to make pretty 3D pictures of your skis, there's not much need for it. I have separate files with just 2D sketches for my mold, and the ski's planform. I just plot straight from that to the plotter 1:1.

i agree that you dont actually need the 3D pictures, i dont put skins on my models, but i do always make them extruded. and if i need the 2D pictures i just export to .dxf to send to cnc guy.

i really like being able to visualize the finished ski. but i am a very visual person

Yah, I know its not necessary. I'd just like to understand the program a little bit better. I do find that I get better using it each time I use it.

how did you sketch everything?
post screen shots of your property tree (or whatever it is called on the left) and your sketchs

so keep in mind that i am an accountant and not an engineer, but what the engineers i work with taught me was that you should always model the way you plan on building.

so with that in mind i sketch my profile i.e. camber, rocker, tip, tail then extrude that (boss extrude button on the features menu) out the distance of the widest part of the ski.

then i create the side cut radius, tip and tail on the x axis then do an extruded cut (its the button that looks like a cube with the center missing, in the feature menu) to get the final ski. i like this way the best.

if you are curious about how to sketch different entities let me know and i can post some screen video of how i do it

Here are my basics...

ALL SPECS ARE IN CM!!!!!

First I lay down axis lines in other sketches for references.

Next I start on the shape. I plot points for total length, waist width, nose width/length, and tail width/length. A 3 point arc connects the nose and tail to make the sidecut. The arc then gets a coincident relation to the FIXED waist point. Then I make splines for the nose and tail. I mirror all this around the X axis to form the complete shape.




Then I make my camber shape. I use the same reference points that I laid out in the previous sketch for total length and nose/tail length. I also add a MAX camber point and FIX that. I lay a 3 point arc similar to the sidecut, and coincident relation it to the MAX camber point. Splines are then drawn for nose/tail shapes.




My last step is to define the flex pattern. Again I use the same reference points and add some more in and FIX them. Then I simply connect the dots with lines for this step.

i like the idea of mirroring about the axis to keep symmetry, r you going to build your core then create an assembly to get final product. i would not recommend this it may be more difficult than necessary.

i dont see why u need the line dimmed 44. i personally stay away from using splines because they are hard to define, and to adjust later. i would add 2 center lines which are tangent to the side cut. that way you can adjust the distance underfoot later.

on your second screen shot to get the extrusion select the arc and splines then select offset enteties, and enter distance. then conect the two lines and exit sketch. then select the sketch, go to feature menu, click extrude.

let me know if that makes sense. have u done the tutorials that come with sw, they are super helpful

Forgot to identify it, but the 44 is the distance center to center for the insert pack. I also mirror around that line, since SW won't let me chose the X-axis to mirror about. The splines are hard to identify, but they seem pretty easy to adjust.

Using this method I can map out a board in about 3min!

Never tried the tutorials. If I have any questions I usually ask my big bro with the mechanical engineering degree. Lately hes been a little busy. I find its also better to get answers from like minded people.

Your method makes sense, thanks for the help!

Now I need to MAKE IT!
