btrueblood thank you for the effort. I did the trim already and the actual impeller resembles drawing more than my 3D model but I am trying and tweaking it bit by bit with center of helix position etc. Unfortunately this is all playing and not really exact science as it should be :D
Almost all old drawings I came across, I was able to model the parts. Few I couldnt, had additional info called out somewhere in notes/PL (like Wil said). This one doesnt have any additional info anywhere, thats why I was sure it is fully defined and can be "easily" 3d modeled.
@ Ed 1.Yes, 2.No...
Like Ed said I presumed its a thread callout and modeled it like helix with a 6in pitch. Position of a helix centerline is .440in dimension. This gives the closest result to the drawing but as you can see in image, the curvature of leading edge is not the same and point on leading edge tip...
Can someone explain how are these blades defined? I am trying to model them in Catia but I am not sure what "lead" 6.000 RH" actually means and and where is the centre of helix twist.
Never seen this kind of dwg before (old dwg) so not sure if everything is defined here or there is some missing...
Hello everyone,
How can i pattern nodules (small pads) on a curved surface. Creating one nodule is not a problem but if i go with user pattern (i have points where pads need to be) all nodule top flat surfaces end up parallel and i need each one to be normal to the curved surface where points...
Fernando,
thanks for the help,
i did what you wrote only problem is it counts in all pilot holes i have on the surface but still, i can work with this.
Thank you...
I did the Tangent Continuity extraction but it still doesnt measure my full edge, just till the next radius,
can you explain what u meant by "then use Measure Item(with perimeter set on)." ?
Hello everyone,
Is there a "quick" way of measuring complete edge of a complex part? (or any workaround)
I have unfolded sheet metal part and need to know outer edge length so i can determine how much time we need for machining...
Thanks.
Ok thanks for answering,
I have no experience with power copy or knowledge patterns/template
so i guess i need to read up on that subject and find some tutorials etc...
Thanks again.
Ok but tbh I simpled up my problem a bit,
what would u do if u had to make surface stamp instead of rectangular cutout
(funny thing is, stamps shape would change exactly like your rectangular cutout in image) ?
Thanks
Hi everyone
Can someone tell me if its possible to create pattern with variable OBJECT. What i mean is this:
Lets say we have thin wall cylinder and somewhere on the wall is small rectangle cutout. What I need to do is circular pattern that cutout around the cylinder but I need rectangle to...
