Patterning is a key feature for any serious membrane structure software. Quality of seams, patterns offsets and compensation make the difference when it comes to build the structure. With our 20 year expericence in this field we are second to none, our patterns are accurate and reliable. ixCube 4-10 tensile fabric patterns have been improved over ixForten 4000 for almost perfect results in any complex scenario. Exact edge matching, exact angle flattening are always under control to the user and the quality of the results can be checked by just looking at the huge amount of built structure spread around the world. When it comes to purchase a software for membrane strcutures the first question should be How did the software learn to make pattern's ?  Yes because tensile fabric patterning is one of those fields where math fails and only experience drives to correct results. Automatic patterns are a NON-SENSE don't get fooled when somebody tells you that patterns can be done in 10 minutes. Patterns are what people will see and what customers are paying for, they cannot be generated by a stupid algorithm that has no knowledge of perception, Yes perception since patterns shape the space and the aestetics of the final result. TAKE care of them. ixCube 4-10 makes them in the right way.
