<p>Hi all,</p>
<p></p>
<p>I have been attempting something similar to what Taz has done.</p>
<p></p>
<p>I would be interested in what Taz and others have achieved in terms of gap tolerances between each panel as well as the approaches to minimising this gap. What is achievable???</p>
<p></p>
<p>I am wondering if I am currently too ambitious with my tolerances - I am currently using 60 unique tri panels from 1500 on doubly curved surfaces and getting a maximum vertex deviation of 80mm which is…</p>

<p></p>
<p>I am wondering if I am currently too ambitious with my tolerances - I am currently using 60 unique tri panels from 1500 on doubly curved surfaces and getting a maximum vertex deviation of 80mm which is approx. 2.5% of the panel edge length, the average deviation is much lower at about 10mm but it is the maximum which obviously defines whether the solution is viable in terms of construction.</p>
<p></p>
<p>From my attempts at this problem I find that a loop of simply re-clustering with relaxation is not sufficient for my purposes. My approach has been to introduce the "worst" panels as seeds to clustering at each iteration.</p>
<p></p>
<p>Looking forward to your responses!</p>
<p></p>
