Opening EasyRx 3D
EasyRx 3D is integrated throughout EasyRx. You'll can access EasyRx 3D here:

-From the Main Menu Bar:

From the Prescription Workspace:

When viewing the File Upload section for a Patient:

When viewing the list of files on the File Upload tab, the following options are available.

Click the file name allows you to open the STL file, you can open the file View mode or Edit model
Deletes the file
Scrubs the file. Read the File Scrubbing KB article here 
Scrubs and remeshes the file.  Recommended before basing
Downloads the file to the default default folder on the browser

Opening EasyRx 3D - View or Edit
When EasyRx 3D is opened from a RX or from the patient, a listing of all STL files displays.  Scroll through the list and click on the file or files to edit

  • If one file is selected, both View and Edit are available
  • If two files are selected, only View is available
  • If you click on a file from the list of STL files for a patient, you can choose to open in View or Edit model

Opening EasyRx 3D from the menu bar
When EasyRx 3D View is opened from the main menu bar, a menu screen is displayed, with three options available:


Allows you to lookup a patient and View/Edit or attach STL files to this patient

Allows you to lookup a prescription and View/Edit or attach STL files to this prescription 

Allows you to browse to local STL files and open for viewing.

Upper: Click the link and browse to the upper STL file stored locally for viewing
Lower: Click the link and browse to the lower STL file stored locally for viewing

User this option to view STL files for a patient without having to add a patient record to EasyRx.

EasyRx 3D View 
Opens a STL file in EasyRx 3D View allows you to view the STL file.   When Viewing STL files, in either View or Edit mode, the following options are available:

The Task Pane includes these options:

Increase the model size by clicking the + / - buttons on the task panel or by scrolling the roller ball on your mouse up and down 
Move the model around the screen by clicking the left, right, up and down buttons or move the model by holding down right click on the mouse and moving the model
Quickly orient the model using the Left, Right, Top, Bottom, Front and Back buttons 

Separates the upper and lower models, if two models are opened

Also, you can spin the model as needed by holding down the left mouse button and moving the model around

EasyRx 3D Edit 
A STL file opened in Edit model displays the model with orange "trim points" which can be adjusted as needed

And the  Task Panel shows the available edit options:

EasyRx File Optimizer

Click to Optimize the STL file.  The file will be automatically optimized. You'll need to close EasyRx 3D and open the optimized file once the process is completed. This usually takes a few minutes. The new file will have the extension "EasyRxOptimized" in the file name. 

Orient Model

Orienting the model is required to do a hollow model or after trimming a model using EasyModelTrim or if EasyRx 3D detects the models needs orientation.

To orient a model
click the left molar, between the first anteriors and click the right molar. 

Trim Model 

Use the Trim Model tools to trim / clean-up the model before Basing:

Trim Model: After adjusting the the trim points, click Trim Model to trim the model. 
Adjust Trim:  Returns the model and trim points to the most recent state before trimming the model, allowing you to adjust the trim points as needed
Restore Original Trim Path:  This is "start over".  This restores the trim paths to the position on the original saved model
EasyModelTrim - EasyModelTrim allows you to re-trim the entire model. When selected, the existing trim points are removed.  To trim the model, you can click around the model or hold down [ALT] and the left mouse button and drag the mouse to draw the trim points.  More information can be found in the EasyRx 3D Edit video series

Add a Base
Regular:  Adds a regular base
Hollow:  Adds a hollow base
Base Height:  Allows you to define the preferred base height:
Thinnest: EasyRx 3D determines the thinnest base height for this model. 
2, 4, 6, 8 and 10mm: The base height is set to the chosen height
Custom Base Height: When chosen, a base pan is displayed, which can be adjusted to the desired base height

NOTE: To simplify trimming and basing model, the add base process also trims the model.  You can adjust trim points as needed, choose preferred base type and click "Add base" and the model is trimmed and based.

Wall Thickness

Only required for Hollow models, choose 2, 3 or 4 MM
Cut Model
Displays a cutting pane which can be adjusted to cut the model before basing. For example, you can position the cutting pane just behind the molars to cut off the back on the model, allowing it to be placed up right ("St Louise Arch style") for printing. NOTE: The cutting pane only works with Regular models
Undo Add Base

After a base has been placed on the model, you can start over by choosing "Undo Add Base"

Add a Label
After a base has been placed on a model, up to two labels can be added
These data files are available:

Rx Number: The EasyRx RX number
Patient Name: The name of the patient
Patient Initials: The initials of the patient
Bin Number: The bin number assigned to the case
Practice Name: The practice name - uses the practice name from Account Settings
Custom Text: You can enter free form text, like today's date

Position First Label: Choose the data fields for the first label then click Position First label to position the first label
Position Second Label: Choose the data fields for the second label, click Position Second Label to position the second label
Add Label: - Click to add the label
Undo Add Label: Click to remove the label(s) and start over

On regular base models, the label is engraved
On Hollow base models, the label is embossed

Save Model
After trimming, basing and labelling a STL file, click Save Model to save the new file. The files is saved to the Patient's File's.  The file name defaults to:

The Patient ID_Base Type(X) with X being a count of each base created.

You can change the file name by clicking in the file name box and using the backspace, arrow and delete keys to remove the default file name and enter the new file name.

Steps to trim, label and save a Base

  1. We recommend running the "Optimize" tool before basing a model
  2. After opening desired model
  3. Adjust trim points, either individually or using EasyModelTrim
  4. Choose desired base type, height and wall thickness (if hollow model)
  5. Add base
  6. Add labels
  7. Save the model
  8. Use EasyFS to open the based STL file via third party software, like 3D Printer software
