Import the Split Bend with STEP Version of "VTube-LASER Demo CAD Model 2"
|
Import STEP File
Step 1 - Install at least version 1.79 of VTube-STEP or VTube-LASER
The STEP version of the Demo Model 2 file is included with this installation. Also, the collect split bend feature is only available in this version or newer.
Step 2 - Clear VTube and Import STEP File
Clear VTube using the Clear Project icon. Change to the Import/Export menu and press Import STEP. The file to import is installed in the \My Documents\VTube\Models folder by default. The filename is "VTube-LASER Demo CAD Model 2.stp".
Make the Tube Transparent
This is not a required step. However, when the the tube is transparent you can see if you have collected either the inner or outer diameter. Selecting both the OD and the ID in various straights will help VTube to extract the OD and the wall thickness at the same time. (The selection process happens in the "Collection The Tube" process shown in the next section.)
Step 1 - Load the Entity Control
Press the Entity button on the right:
Step 2 - Select the imported tube
In View mode, select the tube with a Window using the mouse and creating a window around the image.
Step 3 - Set the Transparency to 0.750
In the Entity Control window Imported Model tab, set the transparency to .750 and press Set.
The tube will now appear like this:
Collect the Tube Straights
Use these steps to collect the tube straights.
Step 1 - Load the Collect Control
Close the Entity Control window if it is open. Then open the Collect Control window.
Step 2 - Be Sure Viewport is in View Mode
To perform a Collection, it is necessary to place the Viewport in View mode. For example, if the viewport is in Orbit mode, then by right click on the viewport to set it back to View mode.
Step 3 - Setup and Start the Collection
In the "Centerline from Cylinder" tab, check both checkboxes, be sure the straight value is "1", then press the large "Add a Cylinder..." button.
Step 4 - Select the Straights 1 Through 4
Begin selecting straights. Select straight 1, then 2, then 3, then 4 like this:
Step 5 - Skip Straight 5 to Select 6
Skip straight 5 by setting the straight number to 6 in the Collect control.
Step 6 - Select Straights 6 and 7
Select the rest of the straights.
Step 7 - Change Viewport Mode to View
Right click on the viewport because there are no more straights to select:
After right click:
Step 7 - Setup to Select Split Bend Surface
Change tabs in the Collect Control to Split Bend Surface:
Set the straight number to "5" because we are going to select a split bend surface that will build a straight 5.
Step 8 - Select The Bend
Select any part of the bend torus that will give contain points at the extrados apex and the intrados apex:
In this case, we only need to select one part of the torus to get to both the inside and outside apexes.
Step 9 - Calculate The Centerline
Close the Collect Control window, then open the Calculate window and press the "Generate Tube Model" button:
Display Parametric Model
The new MASTER model will display on the screen - along with the split bend geometry:
This is the model that should display:
This is the data that should display:
Compress Bender Data for Reporting and Use in VTube-LASER
Step 1 - Compress the Bend Data By Switching Split Bend ON
The data shown above displays the 4th and 5th bend as two adjacent 90-degree bends in the LRA data. VTube can compress these two bends into a combined bend to show 180 degrees - which is what the bender will want to see. Enter the Tube Data menu, press Bend Setup tab, then press the Split Bend Setup button:
This is the Split Bend Setup menu. It is available in both STEP mode and LASER mode for the MASTER data:
Change the Split Bend settings so that the 5th straight splits a bend like this:
When you close this window, the bender data will compress like this:
Step 2 - Switch to LASER Mode
Press the LASER button in the upper right corner of the screen.
Step 3 - Display the MASTER Tube in LASER
Display the master tube on the screen following these steps:
Step 4 - Orbit the MASTER Tube
If necessary, orbit the tube to a good viewing orientation:
The master tube is ready for measuring.
