how to use ecuations in sketcher mode ?

[damiaptr]

hi there!

does anyone know how can I make in sketcher mode a profil generated by ecuations? I know that I can do a curve from that ecuation before and with use edge option I can get that profil, but in this particular case I have to sketch this profil using ecuations in sketcher mode...

I actually don't know another way of doing it. I've always created datum curves and used the use edge option. is there any way you could work around it?

i don't know but may be helpful to you

sketch>relations



after sketching your sketch you can control the dim through relations(equations)

this may help...

stop looking for the ecuations command and start looking for the equations pick.

Take a look at the article by Ed Muirhead on 6/11/2002

Create features based on graphs or equations

It gives the information step by step.

can't use graphs, 'cause in order to schetch the graph traj. I should be able to schetch the trajectory using an ecuation, so... it's a vicious circle.

Using relations in schetcher mode helps, but this way I can control only few points from the profil, others points ain't exactly determined.

I would recomend that sketcher relations not be used. It is better to complete the solid feature and create part relations.



This will allow a user downstream to see how the part is created and driven in one place (at the part level) rather than in many places buried in features.

Try using the datum curve icon.



Under the menu manager select from equation

Then select coordinate system, the type (cartesian etc), then type the equation in. (picture 2)

u can go to sketch mode and use relation in the relation edit file option u can give your equation and get the desired profile.

dear magi,

I know I can do that ... , but I'm more interesed about how can I sketch a profil generated, lets say, by sin(x) function. Using curves I can generate this profil and every point from this curve is a result of this ecuation, but in sketcher mode using relations I can constrain only few points from this curve/spline...
