Thnak you very much. I found what I was doing wrong. I did my valve now it is fully constrained. I know it was very simple and stupid, but I got it I have not noticed that I have to constrain this point on the spline. I will try to fix the rest of my parts now. If I need help( and for sure I need) I will ask more.
Another little tip - if you change this line to center line (upper right corner of screen) you can avoid calculations.
I always try to avoid calculations if the geometry will solve the problem.
I'm also going to nit-pick clearances between cylindrical shafts and the holes they are supposed to go into.
There must be clearance in the real world for the parts to move - might as well design them that way.
I am lost with dimensions again. I attached file where 2 dimansions are still needed but I dont know how to find them. I tried many but without success. Is there any easy way to determine which are missing
Also the one in the picture. 1 dimension is missing, but which one? I tried tangent constrain so it alligned inner circle to outer one but it is still missing constrain.
I have made it fully constrained but I had to add one vertical line, not only dimension. For me it looks strange but if it must be done this way I will leave it
Do you really need to use splines? Much simpler to us multiple radii.
Project the axis and use mirror constraints to make both sides the same.
Do this at the start of the sketch, It will be much easier to constrain.
Start with your functional elements, the diameter at the top and the radius at the bottom and get them constrained first.
Then build the outside around that.
Finally I made sth like this. I put it into assembly, enabled contact set and constrained it. I dont know how to set the cylinder verticaly to ground, and how to move the crank to move piston up and down. How do you set for example having rod placed exacly in the middle od the crank. Aso I dont know how to set crank to do rotating movement, not moving from left to right and up and down.
I will try to show you how to do the assembly tomorrow if someone else doesn't jump in here.
I know you are following a tutorial, but I thought you might want to see an easier technique to model one of your parts.
Closely examine the sketch part and the solid part files attached.
