## create special symbol

Dear all,
I am trying to build the symbol I am attaching (an antenna ). I guess I can do it combining the triangle with the lcrescent symbol.

But I get a moon superimposed to a triangle and I do not really how to move it. I tried many options.

Can anybody help me? I do not understand how this really works.

This was my best and clear try.

Hello Maria,

would you mind attaching a screenshot of your current symbol? This makes it easier to see how far you've got already and where you might need some help.

All the best,
Kristof

Yes,
Here is what I get when I try to plot it.

Hello Maria,

thank you for the screenshot. Now I see your problem. For tilting your antenna dish you need `R` (see the docs under 28.2.3 Macro commands) to rotate your symbol canvas. Then some fancy offsets in x- and y-direction to position the dish over the top of the base and you are all set.

I hope this helps a bit to understand a bit more of the very powerful custom symbol mechanics. Please see my take on your symbol below:

```# Antenna Symbol - 0|0 is in the middle of the triangle base line
#X            Y            size  a1             a2             rot  sym outline        fill
0            0.125        0.5                                      t   -W0.02,black   -Gred
30   R
0.54898992   0.85984632                                            M   -W0.02,black   -Gred
0.72         0.39         1     110            250                 A
1.31661251   0.39         1.8   211.46996069   148.53003931        A
```

Basically I plot a triangle shifted a bit up so the symbol origin (0|0) is in the middle of the triangles base line and construct the dish similar to `lcrescent` (I didn't like the look of `lcrescent` so I build my own). Then I inserted the `R` above the dish to rotate the canvas 30° counter-clockwise. Finally it took some trial & error to displace the dish until it looked descent.

Let me know what you think.

All the best,
Kristof

Dear Kristof,
thanks for your time. When I plot it, I do not see the same way you show in the picture, but it is the antenna I want.
I understood a little bit thanks to your help and made a little "update".

Thanks a lot! a best regards
Maria Eugenia

Hello Maria,

glad you liked it. Just out of curiosity - when you plot my symbol, what do you get? What is different to my screenshot (besides the grey background I suppose)?

All the best,
Kristof

Dear Kristof,
I see the same image as that you have sent. It was my mistake. I introduced a -G option and then I saw everything in red.
Thanks!
