Create spiral

JonnyTech
Is it possible to create a spiral in LibreCAD?
I have a circle and want to spiral down to its centre.
Any help or tips appreciated.

we actually have an experimental plugin "plot".

for example, you can supply equations like:

x = sin(t)
y = cos(t)

you may also choose line segments, polyline, or bezier curves.

for beziers, the current algorithm is not efficient, so try to avoid using something like 1,000 steps for bezier.

Installed (through apt-get with ppa:librecad-dev/librecad-daily)
Version: 2.1.0-alpha
Commit: 2.1.0
Compiler: GNU GCC 5.2.1
Compiled on: Apr  1 2016
Qt Version: 5.4.2
Boost Version: 1.58.0

but it does not have plot plugin.

It supposed to be daily compile, I guess.

Is it not so.

How often it is compiled?

Is PPS ( ppa:librecad-dev/librecad-daily ) is wrong?

It has 6 plugins:

Align
Read ascii points
ESRI shapefile
List entities
Same properties
Sample plugin

Plot is not there. As per about, LC is compiled on April 01, 2016; and
I don't think plot plugin is taken out as "April fool" ;-)

It looks like it's also missing "Read PIC file".
I can't explain that. They both appear in the menu on OS X and Windows.

Please read PPA in place of PPS above.

Can any other Linux user or developer confirm missing two plugins?

To answer your other question...
there have not been any changes to the code in 10 days,
which means there is nothing new to build or release for the daily ppa.

I've been helping my family lately;
and I'm working on other projects that have priority in my life.

I built the master branch on openSUSE with Qt 5.6 and all the plugins were in the menu.
