Finding Layer Area

How would I go about determining the area of a given layer?

I need to make a dynamic cure formula, but I can't figure out how. Obviously the smaller the area the longer the cure time, but where / how do I figure out the area of a given slice? Or how do I figure out the cure time to area ratio or what have you.

Any advice?

Re: Finding Layer Area

Found it, it's the Area command in Rhino after turning a given slice into planar surfaces.

Still working on figuring out the rest.

Re: Finding Layer Area

We already have total area per layer and largest area per layer as variable on gcode box.

I meant how to find the total area of a layer so that I could work out a formula for dynamic cure time. I was looking to see what the largest versus smallest slice size was in a given model. I can't figure out exactly how the dynamic cure notation works.

I need a formula that is basically:

 ( [cure time] = [standard cure time] / [total layer surface area] ) 

But also doesn't allow the cure time to be any less than the standard cure time. I used the new mask creation feature to normalize the UV exposure across my whole build plate, but now my new standard cure time doesn't work as expected.

The standard cure time in my set up will cure a large layer just fine, but won't do jack crap for smaller (read jewelry prongs or bridgework) features. In fact, it's not enough to get layers to adhere correctly or to even form.

So.... suggestions?

Re: Finding Layer Area

Maybe {15/[[TotalSolidArea]]} ?
