What is Unit Agnosticism? Simply said, it is when your symbols and circuits do not rely on a particular measurement unit. Why is it important? Because if you draw a symbol in inches, then you could not use it on a page set to any other measurement unit as it will not scale nor align correctly with the grid. In other words, you would need to draw a symbol or a circuit in inches and redo the same thing if you wanted to use it on a page set to millimeters. Let's have a closer look:
When you first open a new drawing in Electra, the default measurement unit will be in inches (internally Visio uses this unit as well). This is all good as Electra's symbols are designed for this unit and when placed on a drawing, the connection points are always aligned properly with the grid to enable easy, straight and direct connection to wires.
Despite this, increasingly, we find that many users may need to draw circuits in other units like mm, cm or even meters. It used to be, when Electra's symbols were placed on any metric system grid, our symbols will be out of alignment with the grid, and therefore, making it difficult to connect wires that are straight and easily aligned to grid.
With the launching of unit agnostic symbols on Electra E6, this is all a thing of the past. For the first time in an electrical CAD software, your symbols will scale, size and align properly irregardless of whether you drop them on a page with inches, mm, cm or meters as measurement units.
All this is transparent to the user, and happens automagically without the need for a user to do anything. When a symbol is dropped on a page, Electra automatically detects the page units and adjust accordingly.
The best thing is, all user created symbols, including those created before this release will also be automatically scaled and aligned to grid, all transparently, without the need for users to do a single thing. Even when you duplicate a symbol from a page with one unit to another with a different unit, and back, Electra will automatically scale and align everything to ensure that your symbols will be on grid irrespective of your page units. Naturally, when you manually resize your symbol by dragging on the handles, Electra will detect this resizing and retain their sizes to skip automatic resizing.
While we are at it, why stop at symbols? Entire circuits can be automatically resized too. Therefore, when you make a circuit on a page in inches, they will automatically resize and align on a grid with millimeters when copied over, all transparently. Prefab circuits dropped from stencils, user created prefab circuits created before this release, circuits copied from a different page unit will all automatically be resized and aligned to grid transparently.
In simple words, Electra users can now create symbols and circuits and rest assured that all of them will scale well and align on grid, irrespective of whether they choose to create these circuits on a page with inches, mm, cm or meters. That's great, but what if, for some reasons, you don't want to resize automatically? No problem, you can set Electra to resize or not resize through a simple option in Document Options (Automatic resizing turned on by default):
One last thing, when you do choose to draw your circuits in metric systems (mm, cm, meters), our recommendation is that you set your scaling to 1:1.5 or 1:1.25, so that your symbols and circuits is displayed at about optimum size for circuit creation.
