very thin parts

[Gailwrath]

I am having issues extruding very thin parts. I am working on laying out flexable cables. I try to extrude to a thickness of 5 microns and the system comes back with something like dim to small must be .017mm min. Is there a trick to modeling very thin parts. Config option change ? please help.

check your accuracy

Setup


Accuracy


Relative or Absolute


The default is .0012 relative. You can set it to .0001 relative without concern. All molded parts should be set to at least this level of accuracy. Absolute can be set to much smaller numbers, but if the part is dimensionally 'large', this can create problems: I don't recall the details.

Gailwrath,

you can also do this:

config option:

accuracy_lower_bound [value] -I am using 0.000003

these are helpful too:

enable_absolute_accuracy yes,no -allows you to choose between relative and absolute

default_abs_accuracy [value]

cheers,

M

I would be cautious about setting the default accuracy too tight, as a higheraccuracy model will result in a larger file size. If this is cascaded across lots of models, the added overhead on core memorycould slow your system. Machined parts (generally speaking) don't needhigh accuracy, but molded parts and large thin parts may need high accuracy. Other parts that may need high accuracy are surfaced parts of any kind.
