I have no idea how to start the construction of a 3D-model as the design below.
When trying with Lofted Boss it did not construct.
Any ideas welcome.
Just sketch your guide curves the way that they are shown on the drawing. And use a boundary boss
Please see Can someone help me with my school assignment?, even if you aren't a student.
You're going to want to look at the Boundary Boss/Base tool.
With how badly the drawing is done I wouldn't be surprised if this were a school assignment.
I tried doing it quickly and my dimensions don't add up
It doesn't specify on the drawing tha there's tangent relations between the curves.
True but not having tangent relations makes those curves not defined and the drawing misses symbols to refer as center lines for the part.
As I said, the drawing is badly constructed and left for people to interpret it the wrong way on purpose.

+1 I agree. These drawings that dont add up, "left to someone to interpret" make my blood boil. What worse is when..... nvm
What a bunch of negative nellys
You are right....the number don't add up. I just realized in my model, I am missing the radius 100 dimension. Comes out to 103.xx
It's intentionally badly constructed and oddly dimensioned to make people assume things.
This is the closest I get, notice the 18 dimension is at 18.502 and the r10 is really badly placed as it is not defined as being tangent, just like the others.
Outer profile curves can all be tangent except for the indicated intersection and the model is fully defined.
That curve IS tangent actually, if you look the center point of the radius, it is 10 from the bottom of the handle
Why yes it is...doesn't say the vertical on the far right is only 10mm long though.
Doh, just checked and the 18 dimn falls over. Yeah, it's a junk drawing.
And that is exactly why I say the drawing is poorly constructed on purpose and badly defined to cause these confusions
You're also missing a few key dimensions.
Put the 18 dimensions and see if you can get it to fit. Also put the 45 dimension
Okay, I am defeated
Never used a boundary box before. What is the difference with lofted boss?
Tibout Maes ... Just FYI
Whats the difference between a loft and a boundary boss
I tried a few things and this is the closest I could get. The 100, 18, 6, 46 and R120 are the five dimensions that I couldn't get all in once without it turning black. I figured that the 100 & R120 were more important than the others so the other dimensions were left driven. Also assuming that the tip of the R120 is vertical to the centerpoint
Update: Was able to add the missing dimensions. But the cost would be the horizontal relations on the bottom left corner:
Yeah that makes sense Jackie, those are the places I would have chosen reference dims. Maybe that all this is, some of those incorrect dims are meant to be a (ref.). Maybe something in molding or clean up changes the final product and what we are seeing here are reference dims.
btw,.. if you add a center path (the avg of the top/btm, a Loft works very nice..(image)
