Handplane.3dm (13.7 MB)
Hello all again! I for some reason(probably because Im still learning) continue to have troubles creating “pockets” or “engravings” on my closed solid polysurfaces. See attached file. Here are the steps iI have taken.
- Created text and projected onto the surface of the polysurface.
- Extruded Text to a solid “cutter” (also when it extrudes I loose the “hole” in the text like the middle of the “D” and “P” etc.
- I have tried BooleanDifference to subtract from the surface NO LUCK
- I have tried to split, trim, etc and delete cutter and join the surface, NO LUCK
Eventually this will be turned into an injection mold and will be using this object (the finished hand plane) as a cutter to “hollow” out two blocks for injection molding. But for some reason only about 1/2 the time I can get any of these methods to work. Please help me understand what I am doing wrong.
Thanks
Kyle
Multiple causes:
-
Several of the extruded letters contain spurious open surfaces, caused by spurious line segments in the text curves. These surfaces can be selected using SelSrf and then deleted.
Or clean up the text curves before extruding (preferred).
-
There are duplicate surfaces. SelDup and delete.
-
Several of the extruded letters, such as some of the “a” and “o”, are two closed surfaces without a hole. This can occur if you use ExtrudeCrv with Solid=Yes on the text curves. ExtrudeCrv may not recognize that some of the closed curves are “inside” other closed curves, particularly if the curves are not coplanar. One method to fix this is to use BooleanDifference on the extruded letters with the two closed surfaces to create a single closed surface for those letters. Note this may or may not work when the extruded curves are not coplanar.
Do you need to have a draft angle on the letters so that the molded part will release? If so use ExtrudeCrvTapered when creating the cutters.
