QCAD.org Forum

back before I retired, using CAD, and even when I was using a drawing board, I always preferred to use a dot arrow head, I just liked its uncluttered look. A lot of engineers and architect drawings we were issued with used them as well. So, please may we have a dot arrow option please, pretty please

Why don't you create your own dotted arrows?
It's very simple:
1. Create an arrow (perhaps make a block of it)
2. Create a layer with desired color, width and type

I know that was possible in AutoCad, but I can't see a way to replace the arrow or tick in Qcad with a block. And I didn't mean a dotted arrow, I meant a circular filled dot as in the attached.

... looks like you are not the only one who is waiting for that:

Well there you go then it'd make a great Christmas present as well

I would also like to us a dot in some places, rather than an arrow.

Is this possible at this point?

Hi,
The issue is that arrowheads under QCAD are not defined by specific Block's.
In QCAD arrowheads are nothing more then filled triangles each drawn in situ.
(RTriangle::createArrow(...) ... https://github.com/qcad/qcad/blob/maste ... pp#L83-L96)
From the code we can also deduct that the enclosed tip angle is twice 0.165rad or about 18.91 degrees.
ISO would be 30 degrees.

There is an exception and that is when you use the Architectural tick for dimensions ... A short slanted line instead of an RTriangle.

And there is yet another exception and that are the arrows used with Datum symbols.
These last create and use a Block '_DatumFilled' at the end of a Leader entity.
But nowhere that is reflected in the Property Editor ... There are thus Leaders with standard arrows and Leaders with Datum type arrows.
(Also see: https://www.qcad.org/rsforum/viewtopic.php?f=89&t=10694 ... https://qcad.org/bugtracker/index.php?d ... sk_id=2547)

Dimensions have a read only 'Block Name' property but it is unsure if that is the solution and if that is supported ...
... Setting this block property by code did not result in another arrowhead ...
