Posted August 1, 2015 I wanted to build as few supports a possible because extention are material hogs. I found the combo sheet on the bridge calcuator and put these together. These only apply to brick and marble. Wood and rope have different combinations. Am I correct that 5 tiles is the longest we can get between supports? one tile (E)ESE..SESASA (conversion to the 2,3,4 or 5 tile patterns) two tile (AA)AAS..ASAAAS..ASE (conversion to one tile E's) three tile (ADA)ADA..DAS..ASA..SADADA..DAS..ASE (convert to 1 tile)ADA..DAS..ASA..SAA (convert to 2 tile)ADA..DAS..ASA..SAB (convert to 4 or 5 tile) four tile pattern (ABBA)ABB..BBA..BAS..ASA..SABABB..BBA..BAS..ASE (convert to 1 tile)ABB..BBA..BAS..ASA..SAA (convert to 2 tile)ABB..BBA..BAS..ASA..SAB (convert to 5 tile) five tile pattern (ABCBA)ABC..BCB..CBA..BAS..SABRepeat the conversion patterns already listed above. Here are the possible combinations for brick. you put them together like building blocks and letters must match up.AASABBABCADAASAASEBBABCBCBADASESAESESADSESSABSAABAS Share this post Link to post Share on other sites
