Summary0032452: Data Exchange - IGES reader returns invalid shapes if xstep.cascade.unit property is changed from default
DescriptionIGES reader returns invalid shapes when xstep.cascade.unit is changed from MM to M.

Attached file (1 sphere.IGS) and next DRAW script can be used to reproduce issue.

This issue narrowed to IGESToBRep_IGESBoundary::Check method that called in IGESToBRep_TopoCurve::TransferCurveOnFace.
If units are MM check will return error and shape is healed afterwards, if units are M check will return OK and shape will be imported as is (invalid).
Steps To Reproduce
pload XDE OCAF VISUALIZATION
# This can be ignored, since MM is default property value in this case
param xstep.cascade.unit MM
igesread "1 sphere.IGS" t
# Select 2(All roots) -> 1(One shape for all)
checkshape t
# Result shape is valid

param xstep.cascade.unit M
igesread "1 sphere.IGS" f
# Select 2(All roots) -> 1(One shape for all)
checkshape f
# Result shape is invalid
TagsNo tags attached.
Test case numberNot needed

If the value of xstep.cascade.unit parameter is changed by the user, then read.maxprecision.val parameter must also be changed depending on selected unit.
In this case, if xstep.cascade.unit parameter is changed from MM to M, then read.maxprecision.val parameter should be multiplied by 0.001.

Patch is ready for review
