Re: Question concerning extruded objects
It most likely is a memory question. CorelDRAW needs more memory assigned than most programs. Like Photoshop, requires the setup of a scratch disk, without you choosing one, it has the default which it chooses, which may or may not have enough there to support the program. Additionally you may assign RAM by percentages. Beyond that CorelDRAW 11, from what I've read, has an extraordinary amount of undos, which can interfere with memory. Best to cut this number to a reasonable amount such as 25 or under. I do use CorelDRAW X3 on the MAC, but it is in Parallels 3.0 running under Windows on a MAC Pro with 4 gigs of RAM. I did have to tell Parallels to not run synchronized time like 60 seconds, its default, made it 3600 now and there is no slow down in performance. The use of the mouse is different, and Parallels will run a tablet with sensitivity only after unplugging and replugging, then it will work with the Windows driver in my case, other wise the tablet runs in mouse-mode only. There are numberous upgrades since CD11 which you do not have. Trace is far more powerful, there are some new tools such as roughen and smear, a crop tool, fillets and rounds, bevel, spot color support for everything including with transparency. In nearly everything you can export to .pdf, the spot color separations work except in crossing transparency with spot color and duotones, or over a gradient with spot color. So it is very good. Currently since the release of Adobe Acrobat 8.0, these .pdfs made with 8.0 do not import, but you can import and edit .pdfs with DRAW X3 and that is very very handy. If you have Acrobat Professional and find the fonts are not importing to DRAW, you can print from Acrobat, another .pdf where you can actually change the fonts to outlines, as embedding MAC fonts will not help unless they are Open fonts for the PC. This outlining fonts in .pdf requires you print even landscape files as portrait and enter your height and width as custom page sizes. Then the import to DRAW works perfectly and you do not have to worry about a customer's design or fonts changing. Nine times out of ten this works, but the stacking order can vary. I had one file I did an impotition in where the stacking order changed. So you have to be careful still. I still would rather do an imposition in CorelDRAW as it takes so little time, just being able to center anything which is grouped on a page by hitting "P" is so handy. Illustrator does not have an equivalent. I have not used CD11 myself. The situation you ran into sounds like a bug that is inherent in that version. Other complaints I have heard is that OS X will not run CD11 without a print driver installed. DRAW also can suffer if you do not use a font manager and have loads and loads of fonts installed which all eat up memory. DRAW has Bitstream Font Navigator but any font manager for MAC should give DRAW the same benefit as I do not know how the Font Manger DRAW has works with the MAC OS.
There are times when working with extrusions, it is best to work in wireframe view, that way you do no have to stress the resources of the computer to render each and every move.
In your file, if you put your sky on a layer underneath the sun, that may work, or render the sky as a bitmap. Again, I'd just have the extrusion on a layer by itself.
I suppose your backup files are corrupt as well?
Every day's a new day, "draw" on what you've learned.
