- To define trapezium loads, all local coordinate systems of the plates must point either inward or outward. We recommend that you direct all the local coordinate systems inward<\/strong>.
The orientation of upper an lower reinforcement is related to the ori\u00ebntation of the local coordinate system. If you change its orientation for the base plate, you’ll be looking at the upper reinforcement for all plates while for the base plate you’re looking at the bottom reinforcement. That’s very confusing.<\/li>\n<\/ul>\n\n\n\n![\"\"](\"https:\/\/support.buildsoft.eu\/wp-content\/uploads\/2017\/10\/Waterdrukken2.png\")
