Could someone brighter than me help here? I am trying to understand the copies attribute when making a DC. I have read the Knowledge Base about picket fences. What I want to do is similar but different enough not to just replicate the formulas used for fences.
I want to create a glazed screen that has upright frame sections (jambs and mullions) which, for simplicity, would be identical. I want to be able to use the Scale tool to set the overall width of the frame. Uprights need to be at a maximum of 600mm apart in my example and at regular centres. So, when you stretch the frame, the number of mullions would increase to suit. There would be uprights to begin and end and a variable number in between.
The Copies attribute correctly returns the number of uprights required but where I am coming unstuck is in making the replication work. At present, replicas are being made but on top of each other and in an odd location. So I suspect the formula that governs that is wrong. Can anyone spot the error?
BTW, this model only has uprights at present. Once I have mastered the uprights, I will add head, cill and glass. Of course, the number of glass panes and their size and disposition also needs to be controlled by the copies attribute.
