Script generates model from input parameters using SOLIDWORKS API
This PowerShell script allows generating model using SOLIDWORKS API based on the template with specified parameters
- Create two files and paste the code from the below snippets
model-generator.ps1
$curDir = Split-Path $script:MyInvocation.MyCommand.Path
$templateFilePath = $curDir + "\template.SLDPRT"
$outFilePath=$args[0]
$width=$args[1]
$length=$args[2]
$height=$args[3]

Download Template Model and save it to the same folder where the above two scripts are saved.
This is template model which has 3 driving parameters: width, height and length.
{ width=350 }
This will be modified by the script and saved to a new file.
- Start the command line and execute the following command
[Full Path To model-generator.cmd] [Full Path To Output SOLIDWORKS file] [Width] [Length] [Height]
As the result the file is generated and the process log is displayed directly in the console:
{ width=450 }
Template file is not modified and the resulting model is saved with the parameters updated.
{ width=350 }
