model may be merged on multiple svg export

[roipoussiere]

Here is a code that render 2 figures and export them in separated svgs:

import cadquery as cq
from cadquery.cq import Workplane as WP
from cadquery.cq import Vector as V

cube1 = WP('YZ').move(1, 0).box(2, 2, 2)
cube2 = WP('XY').box(6, 3, 3)

def fig1():
    return cube2.union(WP('XY').transformed(rotate=V(45, 0, 0)).box(6, 3, 3))

def fig2():
    return cube2.union(WP('XY').transformed(rotate=V(0, 45, 0)).box(6, 3, 3))

def export(fig, fig_name):
    cq.exporters.export(cube1.add(fig), fig_name, opt = {'showHidden': False})

export(fig1(), 'fig1.svg')
export(fig2(), 'fig2.svg')

The fig1.svg file is rendered as expected:

But in fig2.svg, fig1 and fig2 are merge together, instead of jut fig2.

If I comment the fig1 export line, fig2 is exported as expected:

That has nothing to do with export and everything with add: https://github.com/CadQuery/cadquery/blob/c6c1956429a35ae30a67f62984c1f6f4b979690c/cadquery/cq.py#L458 add modifies current Wokrplane in-place.

Ok so is it related to #593 and will be fixed with #449?

449 will fixes disjoint overlapping solids,it has no relation to what add does and which side-effects it has.
