Hmm, Nate/Fred/kerog what platform are you using?
Nate/Fred are you able to try on 2015.03-2?
I'm wondering if it is Linux specific. (I'm Windows)

Please post Help/Library-info.

Admin - PM me if you need anything, or if I've done something stupid...

Unless specifically shown otherwise above, my contribution is in the Public Domain; to the extent possible under law, I have waived all copyright and related or neighbouring rights to this work. Obviously inclusion of works of previous authors is not included in the above.

The TPP is no simple “trade agreement.”  Fight it! http://www.ourfairdeal.org/  time is running out!

What are you trying to accomplish with the minkowski anyway?

Here's a "bigger hammer" approach to generating the shape.  You might also
want to use str() to generate text1-text3.

<pre> trayHeight = 1.4*25.4; maxCutHeight = 0.4*25.4; baseThickness = 2; wallThickness = 2; cornerRad = 2; text1 = "1.4\""; text2 = "Subtract 0.0\""; text3 = "For 0 to 0.4\""; textThickness = .6; textHeight = 4; topLength=5; riserHeight = trayHeight-baseThickness; baseLength = 2*riserHeight; baseH=(baseLength/2+wallThickness)/sqrt(3); baseL=(baseLength/2); baseH=(baseLength/2+wallThickness)/sqrt(3); baseL=(baseLength/2); topH=(topLength/2+wallThickness)/sqrt(3); topL=(topLength/2); rWall=wallThickness/sqrt(3); rot=[ [cos(120),sin(120),0], [-sin(120), cos(120),0], [0,0,1] ]; polyhedron( points=[ [-baseL,-baseH,0],[baseL,-baseH,0], [-baseL,-baseH,0]*rot,[baseL,-baseH,0]*rot, [-baseL,-baseH,0]*rot*rot,[baseL,-baseH,0]*rot*rot, [-baseL,-baseH,baseThickness],[baseL,-baseH,baseThickness], [-baseL,-baseH,baseThickness]*rot,[baseL,-baseH,baseThickness]*rot, [-baseL,-baseH,baseThickness]*rot*rot,[baseL,-baseH,baseThickness]*rot*rot, [0,-rWall,baseThickness],[rWall*cos(30),rWall*sin(30),baseThickness],[rWall*cos(150),rWall*sin(150),baseThickness], //15-20 [-topL,-topH,riserHeight],[topL,-topH,riserHeight], [-topL,-topH,riserHeight]*rot,[topL,-topH,riserHeight]*rot, [-topL,-topH,riserHeight]*rot*rot,[topL,-topH,riserHeight]*rot*rot, //21-23 [0,-rWall,riserHeight],[rWall*cos(30),rWall*sin(30),riserHeight],[rWall*cos(150),rWall*sin(150),riserHeight], ], faces=[ [0,1,2,3,4,5], [1,0,6,7],[2,1,7,8],[3,2,8,9],[4,3,9,10],[5,4,10,11],[0,5,11,6], [7,6,12],[9,8,13],[11,10,14], [12,6,15,21],[7,12,21,16],[13,8,17,22],[9,13,22,18],[14,10,19,23],[11,14,23,20], [6,11,20,15],[8,7,16,17],[10,9,18,19], [20,23,19,18,22,17,16,21,15] ] ); </pre>

2018.04.01 (win) has CGAL 4.10 (v's Nate's 4.9). (& OpenCSG 1.4.2 v's 1.4.0)

/GL Renderer: Mesa DRI Intel(R) Ivybridge Mobile x86/MMX/SSE2
GL Vendor: Intel Open Source Technology Center /

Intel has always been problematic, for preview. Nate you may want to try
Goldfeather, it should fix the garbled preview. OpenCSG 1.4.2 (without
Goldfeather) has helped in many Linux preview problems recently.

Not related to CGAL error tho.

tp/Marius I'm approaching my depth limit for Linux (and ca't reproduce on
Windows), I suspect kerog's info will be Intel & OpenCSG 1.4.0 & CGAL 4.9.
Where to next?

Admin - PM me if you need anything, or if I've done something stupid...

Then tp/Marius you'll need to jump in here please.

@kerog: What you found is a bug: When rendering, we use some cached geometry
that was generated during the preview phase and this triggers a CGAL
calculation error. I don't think we have a GitHub issue registered for this
one yet, but feel free to open one. The key is that doing F6 directly works,
but doing F5, then F6 it stops working.

A workaround: Do a "Design->Flush Caches" before rendering.

@anyone else: Please open a new thread for other issues so we can better
track what's going on.

@kerog, I do suggest you try the latest  snapshot
http://www.openscad.org/downloads.html#snapshots  .
The newer OpenCSG fixes a number of problems of late.
May or may not fix the F5-F6 issue.
