A Model of Islamic Rectilinear
Fig.5. "Occidental". Design.
By forcing a little the formal rules stated above we arrive to a somewhat different type of rige, slightly changed.
In Fig. 5. we see an example developed with PUERTRA, which shows a different flavour, not longer oriental-
islamic, but what could be called Western (we call it Occidental). In it a rule -R10: frames do not
bend at crossing points- has been not followed. The example shows the possibilities of the program,
together with the apparent goodness of the rige model. In Appendix 1
some more examples are included, also designed and printed by PUERTRA.
