Jumpy doors and stuck faucets
-
Hi folks, new project, new problems. My cabinet doors have plenty of clearance and yet they hang up a little and won't close. The thing I find most interesting is this: if you go to the top view with the layers top & rails turned off, zoom way in on the top left hinge. When the program starts, the doors actually move a little. Very annoying and maybe why my doors stick. If I remove all collision from the rails and stiles they seem fine, but even then the door seems to work it's way loose from the hinge.
Also I cannot figure out why my faucets won't turn.
I have a couple of sections set up to look at, or you could use "xray" mode to see the clearances.
Thanks,
RickPS Just got the faucets. I don't understand physics but changing the density to 2 on the faucets made them work.

The model is too small, that's why the faucets do not work as it should.
I enlarged the model to 200%, twice the size.
Then as I put new ones on "Physics Joints", "Hinge / Servos".
So now it works model properly. -
Hi again Rick,
Hpnisse did a good job with the faucets, but the problem with the door "extruding" itself away from the frame still remains. This is happening because the front facia panels of the door have been grouped with the structural elements at the back of the door. When you click on the door you can see the blue "bounding box" and this is the shape the physics engine sees which is different to what you see. I have fixed this in the attached file by setting all the parts surrounding the door to "ignore" and putting a white centre post for the door to shut against, that is set back so that it is clear of the door bounding box. You can select Edit/Unhide/All to put the yellowish centre post facia back in. The doors should be working perfectly now. When constructing cabinets try to make them as if they are made out of rectangular planks and make each plank a group before joining them in one large group. Any trims or unusual shapes should be set to "ignore" and "no collision" and grouped with the rest.
Cheers,
Kev.
P.S. Please see the other hardware speed thread. Thanks for your contribution!

Hi Rick,
I don't think I explained the bit about how to construct the cabinet doors using rectangular planks very well. It is probably better explained with an example. In this latest attachement, I have taken your original model and by constructing the right door in a different way it now works without having to rescale the model or change collision settings. The stiles and rails of the right hand hand door have been subdivided into simple rectangular shapes that have been individually grouped, which makes the physical shape more like the visual shape. When you run the simulation you will the black debug outlines of the doors. Have a look at the difference between the left and right doors. I have hidden the rest of the cabinet so you can see the doors clearly, but you can restore the model by enabling the "Carcase" layer. Right click on the doors and select SketchyPhysics/debug from the menu to turn off the black debug outline.

You really know your stuff Kev!! Thanks again
