Hi, i dont think, that blends will be a problem. But the vertical segment is. See the attached file. Vithttp://files.engineering.com/getfile.aspx?folder=ee960db5-831d-407c-9da2-b05741ae8f4d&file=taper.prt

This sounds much better :o) Thanks John Regards Vit

not good :o(

Hi, I wonder if you could help me. Imagine that you have a drawing with balloons according to the parts list. It will only show one balloon for every component type. Is it somehow possible to change the settings so, that it would show all the occurences of the current part? I am using NX 4.02...

Thanks JOhn, I havent used GRIP much :o) but I have managed to do what I wanted, you can check the spring model, if you want...you only have to set d1,d2 and spring length to get the spring...I found out, that when you create expression, you have to use 360 degrees instead of pi()...for...

I have created a model, that I thought should work, but it does not. I created expressions : t xt yt and then I created a sketch for zt coor. Then I inserted a law curve, but see what happend. Regards...

Hi, I am using NX 4 and I would like to create a model of spring with variable pitch. How would you proceed with this? Thanks Vit

Hudson, and could you help me with the equations? Vit

Hudson, thank you for the examples... Unfortunately, its not exactly what I wanted...I dont have a problem with using a curve to control the angle along the curve...the only thing is, if for example height of 100mm means 100degrees...but it seems to be...the problem what I had was, that I tried...

John, yes, you can edit it, but I wasnt able to add the scale definition once it had been created without...but no problem.. i have attached the file in nx 4 version...I tried to create expression to control the scale...by adding two equations t and ft...but the problem is, that the scale is...

Thanks John, can you do the scale when the swept feature has already been created?

OK, if you look to the attached file and edit the sketch, there are two driving dimensions...angle and length of the line...I would like to change these two dimensions along the curve with some function...as i said, in proe, you would just do t= 0..1 and l=l*t and alfa = sin t for example...

you still didnt catch, what I thought...I dont talk about the spine itself...lets imagine, that you have section created by line defined by angle and length...and you want to change the angle and also the length of the section line as it goes along the spine... Regards Vit

I dont know, if you understand it right...I thought to change the length exactly the way, you are changing the angle...for example length going from 50 to 100 along the curve... Thanks Vit

thank you John for the model... As already sad, can you also control the length?that would be very beneficial. Regards Vit

I wonder, if you can also control the other dimensions. Lets say length of the line? Thanks Vit

Hudson, to be honest... I dont know, how and when I should use the law method...Well, maybe I have found it...I tried to use swept and it seems to work :o) Thank you very much... Vit

Nx 4,02

Hi, i hope you can help me with the following problem. You would have a oil dipstick, which would be general 3D curve spine. And you would need to create twisted section on it. In proe, you would do it the way, that you would simply draw a line in the sketch and constrain it with angle. And...

to jcbcad: yes, that is what we do...we have castings and machining... machining is basicaly aseembly with linked casting body and then you change the reference set of the casting to empty... the problem is, that if you change the casting, you have to go back into the machining tree to the...
