#No RAM for Attach

Using 3DSR4 Create, Object, Attach gave me a "ERROR: No RAM fo attach", when attempting to unify elements in a single object. I currently have 32 Mbytes, although I admit, it was a fairly complex object. Questions: (1) Is this a bug or a feature ? (2) I was considering upgrading my RAM to 80 MBytes, but was told by my hardware vendor that they were under the impression that software applications on PC's cannot efficiently take advantage of RAM in excess of 64 Mbytes. Is this true, or is it a feature? Your guidance would be appreciated.

Hi Gary, << (1) Is this a bug or a feature ? >> There is a 64K limit on the number of faces or vertices a single object can have. << (2) I was considering upgrading my RAM to 80 MBytes, but was told by my hardware vendor that they were under the impression that software applications on PC's cannot efficiently take advantage of RAM in excess of 64 Mbytes. Is this true, or is it a feature? >> QEMM 7.* can access more than 64 MEG. Note the following.. << where's my memory.. >> Here's a repost from Jamie Clay..(slightly dated but still valid) "If you ever have someone call in who has a system with more memory than AutoCAD or 3DS show available, here is one possible solution. (First, does all the memory count up during initial boot?, if so read on) o Get QEMM 7.04 (actually you can't yet purchase this, the patch is on CIS in the QEMM forum) o Then you use the(undocumented) SCANMEM command to display the amount of memory the machine has. SCANMEM returns a memory range called USEMEM. o That range then needs to be plugged into the QEMM386.SYS's USERAM option in the CONFIG.SYS. Example: DEVICE=C:\QEMM\QEMM386.SYS RAM USERAM=XXXXX-XXXXX From there it works like a champ. Note – you needed to add the RAM option to get Windows to work with it." ————————- Following the above, Tyler writes.. I had trouble with Jamie Clay's instructions until I got on the QEMM forum and learned that I had to boot my computer "clean" before I ran SCANMEM. This means when "Starting MS-DOS…" is displayed, press F5 to bypass your config.sys and autoexec.bat. _Then_ run SCANMEM and add the appropriate "USERAM=XXXXXX-XXXXXXXXX" to your QEMM line in config.sys. -Tyler Colwell Sierra Analysis Group ———————– jonas[adesk]
