Check Roll Up Diameter¶

It is now possible to calculate the roll up diameter of fabric when it is rolled round a tube.

There is a new parameter in Blind Details > Blind Types called ‘Check Roll Up Diameter’, which defaults to false.

If it is set to true, then a function checks the roll up diameter against the ‘Max Valance Diameter’ and if it is greater, displays a message that says ‘The roll up diameter is too large for this option choice [description of option].
The function will have to look at all the option choices and select the correct ‘Tube Radius’ (ie it will be the record where tube radius > 0) and also find the ‘Max Valance Diameter’ from other options chosen (ie the lowest but > 0).

This works in both imperial and metric.

The radius of the roll is calculated as:

R = √(L ×t/π + r2) where L is the length of the fabric, t is the fabric thickness and r is the radius of the tube.

The tube radius and fabric thickness fields are both held in the stock record, so we can perform this calculation.
There is also a field called ‘Max Valance Diameter’ which is where we need to hold the maximum allowable roll up diameter.

Order Processing > Orders > Detail Line Import

At the moment it is possible to import detail lines into an order.
However, the option defaults that get set for these may not be correct, since we created the functionality for roll up diameter, tube deflection and torque calculation.

There is a new parameter in Administration > Parameters > Order/Quotation Processing called 'Import Torque Etc Validation'.
When the ‘Import’ button is used in Orders, it will then employ a function that will run through all the detail lines on the order and check roll up diameter, tube deflection and torque (if the flags are switched on in the blind type record).
