Cannot Replace Below , what does that mean?

Overview

This video explains what happens when you use the “Replace Below” feature in Vectric Aspire when there is no model beneath the toolpath or component. It highlights the unusual error presentation, which appears as red text rather than a standard dialog box.

Steps

1. Select the “Replace Below” icon in the software.
2. Attempt to apply the operation to a model area.
3. Observe the system response—no normal pop-up appears.
4. Read the error message written in red text just below the window: “Replace below”.

Key Points / Warnings

• The error only occurs when there is no model present under the selected location.
• The message is not a pop-up dialog—it is a red text sentence displayed below the window.
• Do not overlook this red text; it is the sole indication that the operation cannot be completed.
• Ensure a model is correctly placed beneath the target area before using “Replace Below.”
