Hi, I've been doing a lot of work on automating the creation of building instructions lately, and have been studying various LEGO Constructopedias. There are places where LEGO uses text to anotate things in their step images (like 180 degree (...) (22 years ago, 2-Dec-02, to lugnet.cad.dev)

(...) The one thing to watch out for here is that floating text will only look right when viewed from a particular angle. Don't forget that LDraw files contain 3D data which can be viewed from all directions. Text annotation seems to me more like a (...) (22 years ago, 2-Dec-02, to lugnet.cad.dev)

Quoting Don Heyse <dheyse@hotmail.spam...away.com>: (...) couldn't you say the text "box" is anchored in a point in space, and ALWAYS faces the camera? Or is there a situation where there's more than one camera at the same time? (I don't know much (...) (22 years ago, 2-Dec-02, to lugnet.cad.dev)

(...) As far as I know, you can't do that, but I suppose you could do it with a new META statement. (...) I think there might be some LDRAW programs out there with a notion of a floor or background image. Those are 2D objects that may or may not (...) (22 years ago, 2-Dec-02, to lugnet.cad.dev)

I was assuming that the user knows the view angle as well as any MLCad rotation steps that are in place when laying out the building instructions, but maybe this is too much work. If I do it as a post processing step, then the user is going to have (...) (22 years ago, 2-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)

(...) MLCAD indeed has a BACKGROUND meta commmand that places an image as a background. This image always faces the "camera", indepedently of the view angle. It will not work in al instances (it might get obscured by the model), but it is the only (...) (22 years ago, 3-Dec-02, to lugnet.cad.dev)

Hmm, you could use the IFPOV and ENDPOV statements: 0 IFPOV 0 text { ttf "arial.ttf" // check your fonts directory for the proper names 0 "place your text here" // well, place your text there 0 1, // thickness of text (text will be 3D, dunno what (...) (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)

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)
