Hello everyone, I would like to ask if the vertical holes printed on your Form 4 at a layer thickness of 0.025 millimeters are round

Hi maizi, thank you for your question! If this pertains to holes added to the model using the Hole tool in PreForm, then yes, they would be round. You can find more information on adding holes here: [customer\_v2](https://support.formlabs.com/s/article/Adding-holes-to-models-in-PreForm)
