Re: Make changes to many polys all at once
Ok, I read it and tried that solution in the post and video, but it didn't work. I understood the process, but if I click "slice to qmid11" the polys "invert", so the part of the poly that was a hole becomes water and the water becomes hole ... Please, could you gently take the "GL_CL_V4_Test.zip" I posted earlier and try yourself to slice to qmid11? Just to make sure that it isn't program-related. Thanks anyway for your kind and fast reply!

Re: Make changes to many polys all at once
I don't know what program made the original polygon, but there is something wrong with it's format or geometry. I took your original data, opened it in QGIS ( Global Mapper should have worked as well ), and resaved the data. I then used that new data to cut a hole in a surrounding rectangle I made ans save the new data as C_64A.shp
That file , when loaded to SBuilderx can be properly sliced to QMID11, and the excess areas deleted.

Re: Make changes to many polys all at once
Ah! So it's not my fault this time Actually I took the original poly and saved it in 4° steps with global mapper but, as you can see in the first posts, the original poly had many problems just from the start. Yesterday I didn't have time to work with sbx, but today I'll have a look. Thank you all for the help!

Re: Make changes to many polys all at once
Yes! It works! I managed to make my coastline finally work! Basically the poly I downloaded from the Internet (GADM if anyone is wondering) was in some way incorrect, so I restarted the project from scratch and made many tweaks with Global Mapper and SBX to make the poly "usable" (if anyone is interested, I'd be glad to explain what I did). After that I just had to follow the normal steps you all know to make the coastline from my poly, and after compiling I saw my perfect coastline from TmfViewer!! Now I'm working on an improved version of my coastline that uses GSHHG data (very high resolution!). Obviously, if I decide to share my works one day, I'll credit all of you!
Note for Luis: Now that I'm working with my high res coastline data (18000+ polys!), I notice that SBX is at its limits, because it keeps crashing (mainly memory errors) and sometimes even corrupts data because of the amount of data it's working with. I suggest you to recompile your SBX with the lastest version of Visual Studio (I remember I have read somewhere you developed your program with VS2005, but I'm not sure), and maybe even build a 64bit version. But take it as an advice, not as a critic

Luis is updating SBuilderX, and yes there is a 64-bit version in testing that will solve some memory problems.
