how do I keep my drawer knob centered on my parametric model when width changes?
The drawer face is a rectangle that changes width, but how do you keep it on the center?
Wow, everything was going pretty hard for me,
it turns out, it seems if you put a thing on the midpoint it stays there. Color me surprised, but thankful. I was making a bounding rectangle, turning it into a construction rectangle, then using it to check size changes.
Finally, I made the rectangle away from the first items to begin the model, so my bounding rect would avoid picking up unhelpful dimensions.
Also, I was having trouble with extrusions not coming along for the ride, and using the object ‘fix’ solves this.
Most of the examples are useless for introduction to shapr-metrics, I hereby rename it, because it’s awsome.
I was starting to hate parametrics, but it’s all gone now. I’m only using the iPad, and that adds a slight difficulty for selecting and accidental touches. It all smooths out with some paractice. Shapr-Metrics! Get Some.
It boggles my mind that text isn’t simpler to use, I would make it possible to simply put text where ever you wish, with out any adjustment handles, or all those annoying circles. Why can’t you just make a text object and put it in the items list, off and on, like everything else. Handy notes are just so…well handy.
I don’t know your exact design but one way to do this is to make sure the drawer face was extruded from a sketch. Align the knob to the drawer face (you can adjust the position later without it losing the center alignment). Now if you move the sketch or change the dimensions of the drawer face, the knob will move accordingly.
Note that you have to use the sketch to change dimensions and move, not the drawer face item… and yes, it’s going to be a pain. Selecting the sketch in the item list will go into sketch mode. If you exit sketch mode, the sketch will be selected and you’ll see the gizmo to move the sketch. Moving the sketch will move drawer face and the knob.
Larger models with a lot of dependencies are currently very difficult to manage. This is partly due to the relationship management (implicitly and explicitly), item/sketch manipulation, and general ui concerns.
There’s another way that involves projects between different sketches but there are some bugs present that make this difficult.
Just read your self response… you’ll learn to hate the parametric implementation again… trust me. It is very hard to create a fully parametric model but hopefully this will improve in successive versions.
