PROJECT - TEC APPLICATION

 

 

 

 

Working on a TEC Application. Building a test setup that tracks live temperature variations and plot on a graph. Did some research and finally found out here http://www.toptechboy.com/.

Thanks Paul for the Python Lessons.

 

 

Test setup was made in Creo

PURGE IN CREO

 Purge Command in Creo :

Purge command in Creo helps to remove all the old versions and retains the latest version of Creo files (prt,asm,drw etc).

Without opening a Creo session, we can execute purge command from any directory. But before that we need to make sure that

1.       An environment variable value set for “Path” parameter.

2.       Paramter value should be equal to the path where the “purge.exe” resides

How to set the environment variable value?

Step 1

Go to System window and click on Advanced System Settings

Step 2

Click on Environment Variables… button

Step 3

From System Variables select

Path and click Edit button

Enter a variable value for path. As mentioned earlier it should locate the purge.exe. If you see an already existing path variable value, use “;” for separating different paths. Say x ,y and z are different path variable values then use x:y:z as depicted below

Normally the path variable value should be “C:\Program Files\PTC\Creo 4.0\F000\Common Files\x86e_win64\obj\purge.exe”

How to execute the purge command after setting up everything?

Go to the folder location where you have the creo files to be purged.

See fg0005.prt.8, fg0005.prt.9, fg0005.prt.10, fg0005.prt.11 and fg0005.prt.12.

And also different versions of fg0003.prt, fg0004.prt and fg0006.prt.

Press SHIFT key and RMB click 

Choose Open command window here.

Now type Purge and press Enter

All files within the folder will be purged and you can see only latest versions of creo files

SEARCHING FOR PARTS WITHIN ASSEMBLY WITH A WEIGHT CRITERIA

Step1

Make sure that your part and assembly template has the following

1.    Parameters Weight and Material

2.    Relations defining the above parameters

 

Weight=mp_mass("")

 Material=PTC_MATERIAL_NAME

 

Step2

Set the configuration option mass_property_calculate  to automatic (calculates mass properties on each regeneration)

 

Step3

 

Setting up the Creo model tree within the main assembly environment as shown below

 

Step 4

Make sure each part within the assembly has an assigned material. Relation calculates the mass and assign the value to Weight parameter

Also the material parameter (Type- “String”) will have the assigned material name.

 

The value for MATERAIL AND WEIGHT for each part within the assembly is visible in the model tree columns against MATERAIL and WEIGHT parameters respectively as shown above

  

Step 5

Click on Find

 

 

Step 6

In the search window, set as shown below and click on Find Now

Parts weighing more than 0.00001 Tons (here mass units in Ton) are highlighted.

Be careful with the units used in the design.

Controling Model quality in Creo Parametric

Controling Model quality in Creo Parametric

Model quality settings in Creo by default allow for a better performance. There are a few tweaking we can do on the model quality settings to get a better model display on the screen.

Below images depict a low model quality setting. A smooth curvy edge is displayed as an approximation by straight lines.

Light reflecting off the surface is not smooth enough too. See below picture.

 

Another setting that controls model display quality is Anti-Aliasing. When Anti-Aliasing turned off ,you get a stairstep-like lines as shown in the picture below

 

Let’s dive straight into the settings that controls display quality in Creo now

1.       Go to Creo Parametric options(File ->Options)

2.       Go to Model Display

 

3.    Go to Entity Display and set the options as shown below

 

Now come back and check the model. If needed, turn the display style to Shading With Reflections and check Ambient Occlusion On
