#TechTipTuesday-- Basic Surface Creation

Posted by John McCullough on Tue, Jul 25, 2017

Don't know where to start with building surfaces? This video from the Kubotek University library provides an example of creation of some nice looking surfaces from existing 3D profile curves.

Video TRANSCRIPT:

We will be using surfacing functions to create the basic shape for the blue area in this model

We are going to use these curves to create our surfaces

Starting with the green curves then the blue. The red lines will be used as cutting curves.

Select Create, Surfaces, Edge Curves

Enter the Curve Fit Tolerance and then OK

Select the 4 curves you want to use for the surface boundary

When you select the 4th curve the surface will appear

Select Create, Surfaces, Curve Mesh

Enter the Curve Fit and then OK

Select the curves for the first direction

Select Accept to start the next direction selection

Select the curves or edges for the second direction

Select Accept when done with second direction to create surface

Select Create, Surfaces, Curve Mesh

Enter the Curve Fit and then OK

Select the curves for the first direction then select Accept

Select the curves for the second direction then select Accept to create

Select Create, Advanced Surfaces, Cover

Select Tangent then OK

Select the edge to be tangent to, then Accept

Select Non-tangent then OK

Select the curve(s) then Accept

Let’s use a Guide Curve. Select Curve then OK

Select the curve(s) then Accept

Select Done then OK in the next dialog

Now let’s trim one of the surfaces. You can use solid trimming functions to trim surfaces

Select Modify, Solid Traim/Break, Curve

Make sure Trim is selected then select OK

Select the curve(s) to trim to, then select Accept

Select the surface to trim and which side to keep

*Curves have been turned off to make viewing selections easier*

Select Advanced Surfaces, Bridge

Enter the Curve Fit Tolerance then OK

Select first surface and the edge

Select second surface and the edge

Select tangent directions. You can flip directions in the conversation bar

Select Accept when done with tangent directions

A preview of the bridge (blend) appears

You can use these buttons to fine tune the blend between the surfaces

Select Done to create the surface

#TechTipTuesday-- CAD Translation Validation for Quality Systems Compliance

Posted by John McCullough on Tue, Jul 11, 2017

 

When precise communication of 3D part data is critical, Kubotek has the tool. Leading aerospace suppliers are using Kubotek Validation Tool to test all CAD translations. Check out how in this overview video.

 CAD Translation Validation for Quality Systems Compliance

 

 

 

 

Video TRANSCRIPT:

  

The Kubotek Validation tool is the premier tool for validating translations

Geometric comparison options define the validation parameters

Authority and derivative data sets are specified for documentation

Results are listed for Master and Copy documents

Red light indicates differences

Differences can be reviewed graphically

The final output of the process is a quality document that can be used for quality system compliance

Certification block for tamper detection

Traceability for Master and Copy files

Traceability for options used

Summary of results

Special case scenarios for validation include handling parts in different orientations

The Kubotek Validation Tool includes an orientation wizard designed specifically for this scenario

Simple parameter selection ensures proper orientation prior to comparison

The result is synchronized orientation of parts

Another special case scenario that is adeptly handled by the Kubotek Validation tool is validation using points

Compare options have been specifically designed to handle the scenario which usually occurs when validating translations into inspection software

Green Light indicates no differences
