Shape Dimension Conditions

Overview

Elda Chrome can force dimension constraints to be observed in the scheduling application to ensure that bar production meets certain criteria before a schedule can be sent to the factory for production.

An example may be that ligature hooks must be at least 5 times the bar diameter in length to meet industry standard requirements.

Before you begin

You will need access to the Products application. If this application does not appears in your list of available Elda Programs, you must request access through Bitberry support. 

Requesting access does not guarantee availability as this is a highly controlled administrative application.

Enabling a shape condition

Open the products application and select the Shape Tab:

For this example, select the TH Shape code then the Calculations and Conditions Sub-Tab:


 

We need to limit the E dimension (The hook). Select the E dimension from the drop down dimension list:

Enter a "Conditional" line within the detail grid:

• Conditional - The setting as a condition restriction only for the shape
  • The formula must be 2 sided and evaluate to a true or false value i.e. A=B or A>=B etc
• Calculation - The setting is an automatic calculation for the dimension
  • The formula must be single sided and the value will be set to the result i.e. 5*DIAM, B + C etc
• Initial Value - The dimension will be calculated when the shape is first created but can be overridden in future amendments by the user
  • The formula must be single sided and the value will be set to the result i.e. 5*DIAM, B + C etc
• Formula - How he dimension is evaluated/appraised
• Error Message - The message that will be presented to the user if the condition is not met on entering/factorying.

Shape dimension settings are saved immediately as the pencil icon disappears from the row header for the grid.

NOTE** Conditional values will not be evaluated unless the CheckScheduleBarConditions Company Parameter setting has been set to a "true" value

Shape Dimension Conditions in use:

With CheckScheduleBarConditions  set to false or not present:

Within the scheduler application create a schedule and set up a TH type bar Item:

Enter a hook value less than 5 times bar diameter and tab off the dimension value:

The value is permitted and the cursor moves to the next dimension sucessfully

With CheckScheduleBarConditions  set to true:

Within the scheduler application create a schedule and set up a TH type bar Item:

Enter a hook value less than 5 times bar diameter and tab off the dimension value:

The value is not permitted, focus stays on the dimension and an error message appears. The value must be corrected before focus will be permitted away from the offending dimension.

If the form is attempted to be close, save will not be an available option:

What about a bar item setup before the condition was imposed

If a bar item was created before conditions were imposed, it will be checked and prevented from being sent to factory until the dimension is altered to satisfy the condition.

Without opening the offending item in the shape calculator, if you attempt to factory the schedule the following request deny message will appear.

If the bar item is opened in the shape calculator (double clicking the row header in the above dialog will open the item in the Shape Calculator) and you attempt to save the item without correcting the error, the request will also be denied:

The constraints will also apply to schedules containing errors that have been:

• Copied and pasted from existing schedules
• Schedule bar details that have been imported via the Teckla/Excel import functions.

Can the conditions be overridden?

Usually, No. A permission is available to production staff only that can override the constraint. When attempting to schedule the invalid item the detail dialog will proved an override  option to allow the schedule to be factoried.
