    If you design the lid within an assembly containing the box you can simply offset the geometry to create the nesting feature. This assumes the box geometry uses the same entities for all the various...

    I don't use that version but I'm thinking to turn off the animation -- at least as a test. I always turn that kind of effect off.

    SWx can be quirky sometimes. The solution to the quirkiness is sometimes less than elegant but there's almost always a solution. It's not just splines, it can happen to almost any operation. Chamfers...

    I do much the same as do others. It 'works' for us. If you have specific information about why you feel SWx splines "do not work" (a very broad statement!) how about letting the rest of us in on it....

    I wish I knew. There are splines then there are splines. I don't know the math but some types are considered better than others for reasons I'm unlikely to ever understand. Maybe your current CAD...

    I'm not sure they would consider this a problem. Drawings are typically not meant to be templates. There are a lot of potential inaccuracies introduced when you print something which is why drawings...

    If your airfoil was plotted using the straight ordinates you have created an airfoil with a chord of 100(units). If the units are inches and you want a 60" chord you would scale the model to 60%....

    I'm not sure I understand. Did you use the published ordinates for the 23012? Using those you need to multiply by the chord of the wing. The chord (X in the tables below) in the published ordinates...

    I drew the spline directly in a drawing (not a sketch) and printed it to PDF-EXchange.

    If the spline was exported it may have been converted to polylines. There's a setting to control which type of entities are exported in a drawing, I think the option is to use Solidworks entities...

    Not a bad experiment, please let us know what happens.

    IMHO you have no prayer of getting the holes to line up. If the parts were produced in a factory with hard tooling then you could do much better but no matter what the CAD models tell you the small...

    If you have questions just ask.

    For a start just open a regular (2D) sketch and draw two lines and fillet between them. Then use those to draw a bent tube.

    For my lower longeron I used a 3D...

    The formed longerons are (or should be) a series of straight sections with small radius bends at the clusters where the longeron changes direction. Your sketches defining the longeron's path will be...

    The dimension feature you mentioned is handy when you're rotating about that construction line. It gives you diameter instead of radius. I don't remember when it was introduced but I can't recall...

    Yep, it's convoluted and only works in limited circumstances but it did what Ron asked for. :| I think his point was to learn about alternatives -- even if they suck a little.....

    I had to try the midpoint constraints because I was sure they would work;

    8461

    Works for me, if you change the size of the rectangle to hole stays centered.
  19. I hope not, I've been doing it that way for...

    I hope not, I've been doing it that way for decades. :P

    Actually there's a more convoluted way that avoids the construction line. Make the center of the hole horizontal to the midpoint of one side...

    I wasn't able to open your file Ron but I played with it a little bit using your image to create similar geometry. I had a couple of theories, one was the lack of tangency between the two elements of...

    What happens if the path and the guide curve are each a single entity? What I'm suggesting is, as a test, make the second part of both a construction line and see if it behaves as you would expect.

    The bolts and other hardware items in the design library have all the configurations for the available sizes already created. The files for these parts can get quite large depending on how many...

    Nope. :D You can ignore a lot of what SWx brings and create dumb(er) solids but I don't see any reason to do that. I like being able to create similar parts editing a few dimensions instead of...
