I’m using the Bank Holiday to make some terrain and have hit a snag with the rules. I want to make huge hills - but how big can I go? (...and by big I mean long.)
Each area terrain feature must “fit into a rectangle of which the length plus the width totals no more than 9 BW”. Great! Figure 1b feature C. Great! So my hill can be 7 BW long by 2 BW wide........errrr! No!
Now measure the length (maximum dimension) of that hill and it is 7.3 BW long (corner to corner) and it’s width (perpendicular to) is 2.15 BW. So I have a totally legal hill whose length plus width totals 9.45 BW......so is it illegal or not?
Now look it’s actual length 7.3BW which exceeds twice it’s width of 4.3 BW so breaks the “The length exceeds twice it’s width” rule. Hence, Figure 1b feature C, which is supposed to illustrate the rules actually breaks them.
Undeterred I now look at Figure 1b feature A. Corner to corner length 6.5 BW and perpendicular width 4.1BW. (OK I do assume sharp edges here) Again totally legal and illegal at the same time but at least this one is meets the width rule.
Doing some maths it would appear that the biggest I can actually go and remain unambiguously legal is just over 6BW x just under 3BW And even then I have to take off any sharp corners to ensure that the corner to corner dimensions are reduced to keep within the width rule.
I think so paddy649. But one can never be sure with these rules!
I rember doing a similar calculation some time ago and 6x3BW with some adjustment was what I came up with at the time. I bit the bullet and made them a tiny bit smaller just in case anyone was carrying a laser ruler.
Paddy, there is an error with Diagram 1b. This is corrected in the FAQ:- "Diagram 1b. The last sentence of the 2nd paragraph should read… “All other area terrain features must not exceed a length to width ration of 2:1.”
Thanks. So Figure 1b feature C is incorrect then is it?
Remember that the dialogue accompanying Figure 1b ‘should’ say:- “Terrain feature C is a gully, its length to width proportions must exceed 3:1. All other terrain features must (not) exceed a length to width ratio of 2:1. The minimum width of any feature is 1 BW; thus the min length of a gully is 3 BW.”
Therefore:- Max sizes = 7 x 1½ BW for a Gully, 6 x 3 BW for other Area Features and BUA’s. Min sizes = 3 x 1 BW for a Gully, 3 x 1½ BW for other Area Features and BUA’s. (But one Area Feature, other than a Gully, may be as small as 1 x 1 BW). Circular Area Features are from 3 x 3 BW if small and up to 4½ x 4½ BW if large.
Now technically a gully could be 7 x 2 BW, or even 8 x 1 BW... ...but then it wouldn’t fit in a quarter when playing on a small 15 BW x 15 BW table. So for practical reasons, with a 1 BW gap between it and a table-edge, 7 x 1½ BW is the max, and even then the gully will only fit in a small table quarter if it is placed diagonally. (But it could be as long as 8 x 1 BW on a larger 20 BW x 20 BW table, or on a BBDBA table)
