If for any reason your model doesn’t fit to the design rules. Here is a way most models can be fixed.
Fixing the size
As listed above your model needs to be between the size of: -Minimum length of 0,2cm x 0,2cm x 0,2cm - Maximum length of 49cm x 39 cm x 20 cm Also have we have seen the button to scale a model. With this feature you can adjust your model to be between the minimum and maximum boundaries.
When you convert a file from MeshLab you might change the value of the length. For example from 1m to 1 mm. To fix this to it's original size you need to scale your model by a factor 1000. If you worked in inches, scale with a factor 25,4.
Fixing inverted normals, bed edges and holes.
To fix these issues, use the repair button on the upper right of the screen. The red cross will open a new interface on your right.
If you see the window in the lower right of your screen. Make sure you check the checkbox of auto-update. This will make sure your stats will adjust after the repair tool has run.
After you have done that you can execute an automatic repair. Press the automatic repair button, then a will appear in the middle of your screen.
You can now choose if you want to go for Default repair or Simple repair. I would recommend going for default. This will run all the repairs Netfabb has to offer. Customizing the settings of the repair is possible but not necessary.
After you have done that, the stats of the model should change. Finally it should look like:
0 border edges
0 invalid orientation
1 Shell (if you have a single object in your stl.)
More shell’s isn’t bad, but 1 is better. After all negative things are repaired, press Apply repair. Confirm to replace the old part for the repaired one and you're done.
Fixing a red model
Red is bad, if your model has a few area’s most likely it can’t be fixed. But if your model is completely red (99% or more). You can change this with a command. Go to Part > invert normals
. Press yes to confirm. Below is a picture of an example of a completely red model.
Don’t forget to select the part first (seeing green corners of the bounding box of the model)
