When placing piers，it can be only selected a supportline one by one.
If the number of piers placed at the same time is too large, this is a very inefficient operation.
Optimization is expected.Thanks！
You should be able to select multiple support lines to place multiple piers at once
I means the method of selection is inefficient.
For example,there are several methods of element selection，such as by "Individual“,"Block”,"Shape","Line".
But there is only one method of selecting supportlines when placing piers,just like by "Individual“.
You can only select one supportline for one mouse action.
We hope it can be selected by "Block” or "Shape" or "Line" or other efficient ways.
