Watch Design
-
Hi,
I'm interested to know if anyone has used Sketchup to design a watch or any part of a watch. I have not been able to find much information on using sketchup on very small (40mm or less) parts. Any help would be appreciated. I'm attempting to create a watch dial at the moment with a 19mm diameter which has the hour numbers cut out of it.
thanks,
Alex

Simple solution, build it 10x bigger and once done reduce it 10x.

SketchUp does have limits on how small edges and faces can be.
The smallest Face that can be created is about 1mm square. When creating a 19mm object, you are likely to create some small geometry where no face is possible.
The answer, as Solo mentioned, is to model at a larger scale. Even though SketchUp will not create some small faces, faces created at a larger size do not disappear when scaled down.

You seem to work in metric. The easiest solution would be to set your units to centimetres and "pretend" to be working in millimetres to avoid the problems the gentlemen mention above and still "think" in millimetres. (Although I think metres would even be better as such an intricate model as a watch can cause problems at even 10x scale).
Now at the end of your work, you can easily scale your model down by 10 (or 1000 if in metres) as Jim suggests.

As has been said...
An easy way is to model with your Model Info units in 'meters'
[with the 'm' suffix set 'off'].
Just pretend you are in 'mm' as you model.
Then no faces etc will ever be too small.
At the end you scale the model by 0.001 [in 2 steps of 0.1 and then 0.01 as Jean suggests
] and change your units to 'millimeters' and it's done

Hi folks.
And, since SU will not accept a scale factor of 0.001, you need to do it in two steps, 0.1 and then 0.01 or the reverse.
Just ideas.
