Several objects or workplane and need to delete all but 1 object

I'd appreciate any simple ways to remove or delete unwanted figures on the Prusa Slicer Workplane. I've Googled and TB's this but I don't see when you import an .stl file into the Prusa Slicer and see them all on the Work-plane how to then "highlight" the unwanted figures and remove them? If I choose just Delete it deletes all the figures. Thank you.

No screen shots shown so I'm not sure about your specific scenario.

First, if you have imported several STLs, all will be selected by default. You can click in the white space below the object list on the right to deselect them, then select the one you want to delete.

More complex, if you loaded an STL that contains several objects, the object list will only show one file name. You can right click on the name and select Split. Which gives you two options, to parts or to objects. To objects will create stand-alone objects you can individually manipulate. To parts will split the model into separate parts but they are all grouped under the same object. You can still select individual parts and delete them though.

Hope that helps.

RE: Several objects or workplane and need to delete all but 1 object

I once thought that arranging objects densely would print faster than printing each one independently.   Do not do this!   Make each piece a sliced g code file.  It takes time for the print head to move from one part to another, there are many nozzle retractions, and filament threads often connect everything.  So, you have sliced a file with several objects anyway.  The printer screen has a “Control” icon.   Once you choose that, the first line is “cancel object,” which leads to “cancel current object.”   When the print head moves to start an object that you don’t want, push the button as soon as you can to “cancel current object.”   You can cancel one or several objects in the file, even take it down to just one.   But separate sliced file for each part is the most foolproof.

You also seem unable to separate objects in source stl, obj, etc. files.  Plus Slicer will do that.  You have to “slice” the big file into individual pieces.  It doesn’t matter if the slice plane intersects other objects because you can right click on the parts that you didn’t want to slice.  They will turn the same color as the bunch of things that are still connected.  I think the smart way to keep just the one you want is to “copy” it with the icon on the top tool bar.  Then erase the whole thing and paste the copy back on the plate.

But sometimes one or a few parts in a combined file don’t  print correctly.  You can reprint them without printing the whole file again by printing again and cancelling everything else.

In PrusaSlicer, click on each unwanted model while holding Shift to select multiple objects individually, then press Delete. This should only remove the selected ones, not all. Be sure not to select the group as a whole. Hope it helps
