Adjusting Memory Use
I did this first part and then realized that the memory use is already maxed out for the installer version (which I have). I increased the memory to 2040, since I figured that was under 2 GB. Same problem.Under Windows, create a text file named SweetHome3D.l4j.ini in the same folder as SweetHome3D.exe, write the max memory Java option in that file, for example -Xmx1024m for 1 GB, then relaunch Sweet Home 3D. For 2 GB and more, install a 64 bits version of Java on your system, download the Jar executable version of Sweet Home 3D and execute the java -Xmx4096m -jar path\to\SweetHome3D-4.1.jar command for 4 GB.
So I tried this second part. But I have problems. Is [java -Xmx4096m -jar path\to\SweetHome3D-4.1.jar] like the txt file I created earlier? Put all of that in a text and save as the [SweetHome3D.l4j.ini]Under Windows, create a text file named SweetHome3D.l4j.ini in the same folder as SweetHome3D.exe, write the max memory Java option in that file, for example -Xmx1024m for 1 GB, then relaunch Sweet Home 3D. For 2 GB and more, install a 64 bits version of Java on your system, download the Jar executable version of Sweet Home 3D and execute the java -Xmx4096m -jar path\to\SweetHome3D-4.1.jar command for 4 GB.
