I have a Maximite schematic I created a few years back for a Wood-Fired Boiler. I saved a copy, renamed it Electric Boiler, and am modifying it so I will have a revised schematic for my new electric boiler.

I want to modify the LM335 temp sensor components (and wiring) and replace them with DS18B20 sensors. I can�t seem to modify the on-screen LM335 component. I have several LM335 component temp sensors visible in my new copied/revised schematic. I can�t find the LM335 component in any of the libraries though. What I want to do is copy that component's graphic design, tweak it and rename it DS18B20. No matter what I try to do, it always remains a LM335. Since I can�t find it in any library I can�t very well go to the library, copy and rename the component something else like DS18B20 which I could then edit using Tool Options. How does one find a component that does not appear to be in any TinyCad library but appears on screen in a schematic? AND, Tinycad crashes just about every time I try to accomplish an edit of the LM335. How do I change the name of a component when I can't find it in any library? What the heck am I doing wrong? I thought it might be the TinyCad version 2.90.00 so I found an older version 2.80.08, same issue.

Okay, I officially gave up and created a new library and new symbols. Never could find where the symbols that appeared in the schematic were stored. Since I could not find them I couldn't edit them or copy and change them. But it is all good now. Work-arounds are sometimes a good solution!

A buddy used TinyCAD and had to make a few edits to a project with notepad.

TinyCad .DSN files are XML structured Ascii text. Be careful not to break
the structure. Work on a copy. The libraries are stored in SQLite and are
not easy to edit. He edited the library and then export all symbols to XML.

Its been a few years. So I am not sure if the information still valid.

Here's hoping this can be helpful.
