Title Slide

Welcome to the spoken tutorial on ‘Handling 3D models and CAD in Osdag’.
Slide:

Learning Objectives

In this tutorial, we will learn to,
  • Handle 3D CAD model in Osdag
  • Export a CAD model from Osdag in standard file formats
  • Import and view the CAD model in FreeCAD


Slide:

System Requirement

To record this tutorial, I am using
  • Windows 11
  • Osdag version v2021.02.a.a12f, and
  • FreeCAD version 0.20


Slide: Pre-requisites


https://spoken-tutorial.org

To follow this tutorial you should have,
  • Osdag installed on your system
  • Basic knowledge of structural steel design
  • Basic knowledge of any CAD manipulation software


The prerequisite tutorials are available on this website.

Slide:

Code Files

  • The files used in this tutorial are available in the Code Files link
  • Please download and extract them
  • Make a copy and then use them while practising


Point to the home page of the Tension Member Design >>

Select Bolted to End Gusset module.

Let us switch to the home page of the Tension Member Design.

Select Bolted to End Gusset module.

Click on Start.

Click on File >>

Load Input and select 3Dmodel-sample-design.OSI

Click on the Design button

Click on the disable Input Dock and Output Dock buttons


Click on File >> Load Input

Select 3Dmodel-sample-design.OSI


Click on the Design button.


Also, I have disabled Input and the Output Docks for a better view of the CAD window.

Osdag:

Point towards the CAD window

Point to Log messages window

We see the CAD model and log messages as the design is successful.
Osdag:

Point towards the 3D CAD model

Osdag provides a 3D CAD model for a better visualisation of the designed component.
CAD window:

Press the left mouse button , move the mouse sideways

Rotate the CAD model by pressing the left mouse button moving it sideways.
Point to the model. This allows us to view the model from any side in detail.
CAD window:

Scroll the mouse wheel up two times

Zoom in the CAD model by scrolling up the mouse wheel.
CAD window:

Press the mouse wheel to see a 4 sided-arrow.

Press and hold the mouse wheel,

Drag the mouse to the right or left.

Pan the CAD model by pressing the wheel on the mouse and moving it sideways.
Point to the model. This allows us to view each component of the model in detail.
CAD window:

Press the mouse wheel to see a 4 sided- arrow.

Press and hold the mouse wheel and Drag the mouse to the right or left.

Again, press the wheel on the mouse and move it sideways to get back to the previous view.
CAD window:

Scroll the mouse wheel down two times

Similarly, zoom out the CAD model by scrolling down the mouse wheel.
CAD window:

Point toward the global axis

The orientation of the CAD model in the global axis can be noted from the reference axis below.
CAD window:

Point toward the global axis at the bottom right corner.

Only narration Let us now import the CAD model and do some post-processing.
Only narration For this, I will use FreeCAD.


Users can use AutoCAD or any other software of their choice.

FreeCAD GUI: I have opened FreeCAD.
FreeCAD GUI:

Click on File >> New

Go to the File menu present at the top left corner, and select New.
Only Narration A new FreeCAD application window will open.


Let us now import the saved CAD model.

FreeCAD GUI:

Click on File >> Import.

Go to the File menu present at the top left corner, and select Import.
Import File Window:

Navigate to Osdag_workspace directory

Click once on the Osdag hyphen workspace directory where I have saved the model.
