Point file.pts import truncating accuracy

All,

I'm trying to import a series of points, generated externally and formatted into a .pts file. I'm following the route of Point -> Offset Coordinate System -> Import.

I have a previous model where we've done this and the points are reported at full accuracy (7 or 8 decimal places). However, today when I import the points the values are being truncated (or rounded) to 3 decimal places, which is enough to create visible imperfects at the scale I'm working. If I manually edit a value with more decimal places they are truncated (or rounded) off again.

Is this related to model accuracy - which is currently absolute, 0.01 (mm) - or a config option somewhere?

Thanks!

Check that in your config.pro the following setting is set:

default_dim_num_digits yes

On Creo 2.0 M100, I tested that when I changed it to read:

default_dim_num_digits no

the system then started truncating the .pts imported dimensions to 3 decimal places (the value of default_dec_places setting)

Thanks Paul!

I haven't tested your solution but I'm prepared to believe that it works.

The first answer I got was via the email exploder:

“Not sure what release your using: If it’s Creo 2.0 try this config option: default_dec_places

Setting Range is (0 – 13)”

Sure enough, changing this from 3 to 6 caused .pts values to be imported at their full accuracy of (wait for it) 8 or 9 decimal places (depending on total number of digits – actually 10 sig fig). Go figure….

Not sure about that - my creo works as intended:

it rounds to the correct # of default_dec_places if default_dim_num_digits no

You know, there just might be a 3rd option that overrides the above two in unexpected ways
