Create new Tin based on highest or lowest of several Tins

Post by Roger Walker »

Firstly, new user and forum member here.
From the UK and new to 12D although not to this type of software.
I am using the practice version whilst waiting to start work in NZ.

Just a quick question - is there a macro or built in command to create a TIN from multiple TINS based on a highest/lowest criteria?

I realise this is possible by creating intersection strings and fencing. I was wondering if it has been automated in 12D at all?

Thanks and hope to become involved in this forum more once I have a dongle.

Welcome to the 12d forum and community.

In 12d Model, there's an object called a SuperTin, which is effectively a merging of multiple tins. However, this merging is done based on the order of tins, which you can set/change, rather than the highest/lowest. This tends to make more sense in most practical cases- design overrides existing, for example, regardless of whether design is in cut or fill (higher/lower).

There is also an option- Grid of Min/Max Tins- which creates a grid of points at a user-defined spacing with the z-value of those points taken as the minimum/maximum of several given surfaces (tins). You would then need to triangulate those resulting grid points to get a tin surface, but that's easy enough to do (and you could always combine both steps in a chain).

Caveat: some of the above may not be available in the Practise Version, but are definitely available in the full version.

A new built-in panel "Grid of Min Max of Tins" was added to v12; it runs a bit faster than the old macro panel.

Cheers,
