Hmm... The flag 6 x 4 (#43) is actually 6 x 3 1/3. Flag 6 x 4 (#43P01) is 6 x 4. Strange. I do not own any of these two parts, but I think part 43 is either mesured wrong or the description is wrong. Or part 43P01 is wrong... Jaco "Jonathan Wilson" (...) (22 years ago, 12-Dec-02, to lugnet.cad.dev)

Can someone explain why the "flag 6 x 4" and the "flat 6 x 4 with jolly roger pattern" are different sizes? Is this an error? (22 years ago, 12-Dec-02, to lugnet.cad.dev)

(...) My opinion is that this isn't a significant enough problem to worry about. Further more, I consider this is a renderer limitation and not a problem with the part itself. Therefore, feel free to ignore this if it suits your purposes. -Orion (22 years ago, 12-Dec-02, to lugnet.cad.dev)

Niels, I'm not sure what to do about arrows that are hidden because the view angle hides it. Do you have any ideas? It seems to me that it is just like any other part that is hidden from view. You can't see it. Do you have ideas how to work around (...) (22 years ago, 3-Dec-02, to lugnet.cad.dev)

Thanks Jeroen, I guess there are multiple issues here. My original thoughts were primarily restricted to my LPub centric perspective, where we create step by step building instructions with a fixed view angle, and use rotation steps to virtually (...) (22 years ago, 3-Dec-02, to lugnet.cad.dev)

It is not only about adding text to a 3D world or a 2D render of it, but also about arrows. Arrows are (can be) used to point to a specific part or a group of parts. What about when this (these) part(s) are not visible in a different camera (...) (22 years ago, 3-Dec-02, to lugnet.cad.dev)
