Inverting parts symbols

#1 Post by carlmart » 14 Jan 2020, 13:31

It's been some time since I don't use DipTrace, and I don't remember how you did (or if you could do it) invert a part symbol.

That is, I know I can use R to rotate the part, but that is not enough.

The part is a transistor, and I need the emitter to be upwards, collector downwards and base to the left.

How do I get there? I'm sure there must be a way. Even Spice allows doing that.

OK. Got that.

Now how you pick the part and move just that part, not the connections?

Before re-orienting the component, right-click on it (not its pins) and select "Disconnect Wires" in the pop-up menu. After the component has been re-oriented, reconnect the wires.

OK. Another one, probably the last one.

How did you do to move a whole schematic or pcb job?

I remember you selected them as a group, but then I can't get them to move.

1) Make sure all objects are unlocked before trying to move them by first selecting everything (Ctrl + A), then right-clicking on one of the selected/highlighted components (not its pins) and finally selecting "Unlock Selected" in the pop-up menu. (If everything is already unlocked the only lock/unlock choice that will appear in the menu will be to lock things. Ignore that one.)
2) With all objects still selected/highlighted, either move everything by left-dragging one of the selected/highlighted components (the rest will follow the leader), or set the grid to a value equal to the desired distance and use the arrow keys. (Note: You will need to re-select all objects after changing the grid value.) Keep in mind that the time it takes the program to execute each move step is directly related to the number of objects selected/highlighted along with your computer's processing power/speed.

Is there a way to separate a given transistor pads, just a little bit, so I can use thicker traces or just keep pads well apart?

It's easy to separate transistor pins a little when assembling by hand.

Now have a look at the image. Is it possible to "trim" trace junctions when going from tick to thinner ones, like what the red lines show?

Or use some other trace shape that would do that automatically? Let's hope my question is clear.

Is it possible to "trim" trace junctions...
No. As far as I know, the only way to smooth over undesirable transitions in the current version of DipTrace (3.3.1.3) would be to spend some extra time covering them with custom-shaped copper pours assigned to the same net. DipTrace has a "neck-down" feature (Route > Route Setup... > click on the [Settings] tab) that I think is enabled by default, but it won't eliminate those undesirable transitions.

p.s. You can add more trace nodes by hovering over the desired location on the trace and pressing the "n" hotkey. After that, just left-grab either the new node or one of the newly-formed segments and drag it somewhere else. Having the transition line up the pin entry might be a little more pleasing to the eye. Here's a comparison...

Today I was commenting with a friend that I miss my old DOS pcb design program, called Easytrax, where I could do whatever I wanted, with absolute control and precision. More than with any modern program.

You didn't tell me if it's possible to increase the distance between transistors pads. I guess it's not, and that I would have to design a new part myself.
