hello to all:confused:

I have a problem I can't fix. I created an evolving circle curve, then I created another one that starts from one point of the first. I can't join them. If I go in an example contained in a "cylind-wheeled" part for this "approximate copy" of two curves, I see a pink icon with two handkerchiefs and indicates "curve" as a type of future. but I tried to look in a thousand corners of the menu, but I can't find it! Can you help me please?
Thank you.
 
makes you copy of the two distinct curves: Not a single unit. I try to save some pictures to make you understand. what I am doing is soon said: I want to do a part gear with an evolving profile in metrics completely parametric for:
1) laser or water cutting profile (maybe end with milling or grinding but using the same profile
2) insert in a dynamically simulated assembly, the gears (also with circle arc) accurately managing relative and absolute positions.

I'll explain why. and I assure you that it is not a mechanical enjoyment exercise. It makes a very important sense.

I have to be able to insert module, tooth number, width and get finished gear and ready for cutting... .
 
Take a look, I created two curves, then I copied them.
I noticed that "approximate" only succeeds if the two curves are tangent among them.. .
Hi.

copy-paste a single curve (selected as geometry) and then in the feature open references and add in details the other with ctrl.
 
Thank you. perfect! I got an evolving gear for laser/water cutting completely parametric, even for internal teeth. really great proe!!

after 3 years, isn't that you might/wish/please share this file?
I am next to starting the pc from the window
 
maximum, I send them the model of a fully parametric evolving wheel.
I put the associated drw, even that is parameterized in the sense that the aligned section changes in case there is a number of teeth equal or odd to have a correct representation in section (the tooth is not dissected: but it is longer to say it to words than to see it).

It is made with wf 4, if you need older versions maybe in backups I have the model made with wf i

some very important clarifications if you want to pass the profile to a tool machine.

1) missing the feature of the connection radius at the foot of the tooth. I remember that I had put it and parameterized it, but with a high number of teeth failed regeneration. You can fix it, but at the time the thing for me was not vital

2) this is very important. in the model is created the evolving curve, and is exact in the sense that it is generated by the equation written in polar coordinates. but when I build the tooth feature I use a spline. this spline passes for three intersections of the evolving curve with the background, primitive, external diameters. to increase the accuracy (fundamental in its case) you can increase the number of diameters in order to obtain more points of support for the spline. you can parameterize everything and do it automatically.
ruota_dentata.webpguide parameters are module, tooth number, pressure angle, width.

ooops, I wrote them with netbook, the parameterized dwr I have on the work computer.

I'll post it.

Thank you very much
especially for giving me her, giving me importance tohahahahah
works wonderfully
