2. Preparations in I-DEAS

Start up I-DEAS. You can disregard the console window that shows up in the background.

In the I-DEAS Start window, either find your cunixid in the listbox, or type in your cunixid (your account name, e.g. dd2010) into the textfield immediately below the listbox.

In the textfield labeled Model File name, type in the full path for a new I-DEAS model file. Note that this is not the path to the file you saved in StudioTools - we will import that file in a later step. For now, create a new and empty model, e.g. H:\wheelUnder the field labeled Application, choose Simulation, and under the field labeld Task, choose Master ModelerNow click OK to start I-DEAS.

If and when you are asked to create a new Model File, select OK.

Once I-DEAS starts up, you will notice a large frame with black background and a coordinate system, which is used to visualize the model. On the right-hand side, you will find a palette of tools, and the bottom of the screen features status and entry frames.

I-DEAS features many applications: Design, Simulation, and Manufacturing among others. We will be using Simulation for the analysis of the wheel. Each application encompasses several tasks, which are usually carried out in order. For our purposes, we will be using only a select number of tasks. Depending on the task, the types and availability of icons changes. Within the task Master Modeler you will find icons that facilitate the generation of a model. We will not be using these icons, as we are importing a model from StudioTools.

There are a number of icons that are available in all tasks, three of which you may find useful:

  • Redraw Screen: When switching from another software, e.g. StudioTools, to I-DEAS, you may find that the visualization frame does not update. Use Redraw Screen to redraw the visualization frame.
  • Wireframe: Display the model as a wireframe
  • Shaded View: Display the shaded model

In terms of navigation, you will be using the keys F1 to pan, F2 to zoom, and F3 to tumble. The controls are somewhat different in their handling from those in StudioTools. To use the navigation tools, press down the appropriate key on the keyboard, and move your mouse to pan, zoom, and tumble.

As the first step, you will set the units. This step is crucial in that the results of the analysis reflect the units set in this step. Under Options, select Units

In the list of available units, pick a unit that you feel most comfortable with. For the remainder of this tutorial, we will be using Meter (newton), the first item in the list of available units.

The x-y plane on the screen, also called the workplane has a default size of 20 cm x 20 cm.

To import the model from StudioTools, select File, then Import

In the list of available formats for importing purposes, find the format STEP and hit OK.

In the next dialog box, select the small file icon next to the textfield labeled STEP File to Import.

Find the file you saved in StudioTools. You will notice that a .stp, as well as a .stp.ICON file are available for each model you have exported. Pick the file with the .stp extension and choose Open.

At this point, one of two things may happen. 1. I-DEAS imports the file, or 2. I-DEAS does not.

If you find that nothing happens for a minute or so, I-DEAS will finally return an error in the status frame in the left lower corner of the screen. The error reads Launch timed out. This means that the translator, which imports the STEP file could not be started. If this happens, close I-DEAS, and start it up again. You will need to repeat the prior steps to prepare I-DEAS. The translator should then be able to start.

Once I-DEAS starts importing the file, you will notice a dialog on the screen, which interactively reports the status of the process.

Once the importing process has completed, hit Dismiss on the import summary dialog.

Use the navigation tools F1 to pan, F2 to zoom, and F3 to tumble, so that your model appears in its entirety in the visualization frame.

You should now visually test whether or not the model has been imported properly. Shade the model, and tumble around in the visualization frame to inspect the wheel. If there exists any discrepancy over the model as it appeared in StudioTools, you should re-evaluate the preparatory steps in StudioTools. You may wish to consult with Alex to figure out the problem.
