Occasionally, while manually counting symbols, it can be helpful to isolate the symbol you’re currently working on.
When is isolating symbols helpful?
It’s generally helpful in the rare scenario where both the following apply:
- Your PDFs are actually images.
- The real world paper size of your PDFs is very small (e.g. A4).
PDFs that are actually images
Where your PDFs are actually images, Countfire doesn’t have enough information to allow automatic counting.
In these cases, manual counting tools are used to count symbols.
Very small real world paper sizes
Because the size of the manual counting “point” is fixed, when the real world paper sizes of your PDFs are very small (e.g. A4), this causes the manual counting point to appear larger than normal.
Depending on the design of your PDFs, the number of manual points can make the drawings very busy, and because these manual points are larger than normal, they can sometimes obscure unrelated symbols.
In the clip above, you can see the majority of the drawing has been manually counted, and while trying to count the remaining “Switch” symbols, it’s harder to clearly see where those symbols are.
How can I isolate symbols while manually counting?
- Load a drawing within Countfire.
- Navigate to the “Measure” tab (shortcut to cycle through tabs = W).
- Toggle all symbols off (Shortcut = T).
- Using the checkboxes to the left of the measurements you need to work on, selectively toggle those back on to display them on the drawing.
- Manually add points to count the relevant symbols.
In the clip above, you can see the drawing is initially very busy. Then, once the “Switch” measurement is isolated, it becomes much easier to count those specific items.
How to: Use demarcations.
