Introduction

QElectroTech is an open-source electrical schematic design software created by Laurent Trinques

First of all, my thanks to Laurent for such an amazing piece of software, and to everyone who has contributed to this project. Here you have the software in case you feel like giving it a try. It’s not more powerful than Eplan, but it rivals it like a true champion!

How to generate an automatic table?

First of all, we need to know how to generate automatic tables in QElectroTech. For this, there are two cases: if we want to add automation based on project data or on elements in the schematic: Project > Add a summary and Project > Add a nomenclature.

Once inside, we will be able to make custom SQL queries:

Page Index

To automate the page index, we will do it from ‘Add a summary,’ and I recommend the following SQL:

				
					SELECT
    pos,
    title,
    author,
    date,
    indexrev
FROM
    project_summary_view
ORDER BY
    pos,
    title,
    author,
    date,
    indexrev;

With this query, we will automatically obtain the following table:

List of elements

To automate the list of elements, we will do it from ‘Add a nomenclature,’ and I recommend the following SQL:

				
					SELECT
    label,
    diagram_position,
    position,
    designation
FROM
    element_nomenclature_view
WHERE
    (
        element_type = 'terminal'
        OR element_type = 'thumbnail'
        OR element_type = 'simple'
        OR element_sub_type = 'commutator'
        OR element_sub_type = 'coil'
        OR element_sub_type = 'protection'
    )
    AND designation IS NOT NULL
    AND designation <> ''
    AND label IS NOT NULL
    AND label <> ''
ORDER BY
    diagram_position;

With this query, we will automatically obtain the following table:

As an alternative, instead of using position and diagram position, we can use the page so that it’s easier to read.

The SQL query would look like this:

				
					SELECT
    label,
    title,
    diagram_position,
    position,
    designation
FROM
    element_nomenclature_view
WHERE
    (
        element_type = 'terminal'
        OR element_type = 'thumbnail'
        OR element_type = 'simple'
        OR element_sub_type = 'commutator'
        OR element_sub_type = 'coil'
        OR element_sub_type = 'protection'
    )
    AND designation IS NOT NULL
    AND designation <> ''
    AND label IS NOT NULL
    AND label <> ''
ORDER BY
    diagram_position;

With this query, we will automatically obtain the following table:

Summary of elements

To automate the summary of elements, we will do it from ‘Add a nomenclature,’ and I recommend the following SQL:

				
					SELECT 
    designation,
    COUNT(*) AS Total
FROM 
    element_nomenclature_view
WHERE 
    designation IS NOT NULL
GROUP BY 
    designation;

With this query, we will obtain an automatic table of all the references we have placed in the elements under the concept ‘Article number.’

With this, we will get a pretty good list to give to our purchasing colleague, saving them a few hours of counting and, most importantly, reducing human error ^^.

I hope I’ve saved you many hours of engineering work, since a good engineer doesn’t charge by the hour but by knowledge.
