Alias UGS NX DirectConnect
is a stand-alone utility that allows the exchange of 3D model data
between Alias and UGS NX.
UGS NX Requirements
- UGS NX utilities supported now include
versions 16-20, NX, NX2, NX3, NX4, and NX5. (NX5 does not require
the NX Open runtime license.)
- An Alias software product.
Before you create the model
In the Construction
Settings window:
- The Rational geometry
flag can be toggled OFF.
Set tolerances as follows:
- Curve Fit Distance =
.01 mm (lower as necessary)
- Curve Fit Checkpoints =
10
- Max Gap Distance =
.01 mm (this value should remain the same as Curve
Fit Distance)
- Trim Curve Fit =.005
mm (lower as necessary)
Workflow
Before transferring geometry
between Alias and UGS NX, consider the purpose of the transfer
to plan an appropriate workflow.
Two common workflows
are:
- Geometry (describing mechanical components)
is transferred from UGS NX to Alias to be used as reference
data for concept design surfacing, then the Alias surface model
is transferred back to UGS NX.
- An Alias model is transferred to
UGS NX, and both Alias and UGS NX Databases are developed independently.
Later, the modified Alias model is transferred again to UGS
NX, replacing the Alias geometry from the first transfer. In
this scenario, all work done in UGS NX on the first Alias model
transfer will affect the new, modified geometry.
There are many variations
on these two examples. Whatever the transfer scenario, carefully
plan the transfer process, to ensure that the appropriate data is
written out and is useful.
