How to add dimensions for lofted parts

[Simon.Uniqa]

I have recreated a drawing from the screenshot http://prntscr.com/j8aj0z (the screenshot taken from SolidWorks drawing).

As I mentioned on the screenshot, I can't create a center line inside in the cone created by the loft tool.

Can somebody help me to add the dimensions?

Thanks in advance.

Create a sketch, 

Sketch > Project > Project Intersect - select Body, for type in the dialogue box,

the click on the lofted body, you will get the outline of the body into your sketch, draw lines across this sketch, and a centre line from the mid points of the red lines in the picture.

Might Help....

You might want to share your model.

Hi @Simon.Uniqa,

Are you trying to define a centerline in a sketch or in a drawing? If it's a sketch, @davebYYPCU's approach should work. If it's a drawing, you should be able to define the centerline by clicking the two lines you want to create a centerline between, assuming the section of the loft results in these edges being straight lines in the drawing:

Hope that helps; let us know if not.

Thanks,

Jake

I am having issues with this also. I have a lofted surface that I cannot dimension on my drawing. I had to actually go back into my model and make a sketch and then dimension that sketch. But it is not quite right, had to guess where to add point to dimension from, could not select arcs or lines

here is a link to my model

Can anyone help?

Hi

Probably should be a new thread, but as Patrick has already posted here...

I have a part that if I sweep I can dimension as illustrated, but cannot dimension if lofted...

example model

another part I battle to dimension:

a) a extruded rectangle with rounded edges - radii dimension 100%

b) a lofted sloping rectangle with rounded edges - radii dimension 0%

c) a swept sloping rectangle with filleted edges - radii dimension 0%

I have had some luck, by going bach to the design workspace, create a plane where i want my section view to be, then do a section analysis using that plane, the i make a sketch on that plane, and project my geometry to my sketch, finish, go to the drawing workspace, make my section view, show my sketch and the dimension the sketch. Then i can get my print to my customer.

Real pain in the ass, and it doesnt always work. Thats when i dxf my sketch out to our 1995 version of bobcad wich is a real easy software for drawing in 2d, 

I wish fusion could just make simular for thier drawing workspace

thanks! 🙂

(drawing environment)

body visibility off

sketch visibility on

dimension

body visibility on

also clarifies my workflow (include fillet in sketch etc)...

so with the part I was playing with, without the sketch the R50 & 17.5 (loft rails) were unobtainable, the R5 is a body fillet...
