I am an AC26 user but have a need to reinstall and use AC18 because I want to use Cigraph's Architerra. from that version. I have original installation disks for both. Will reloading an old AC version stuff up my current AC26? Should I reinstall AC18 on a separate folder or take other precautions?
Architerra is an Archicad Add-on from Cigraph, an Italian company. It is a very useful site and landscaping add-on that converts survey drawings and surveyor’s data drawings into 3D contour drawings for site plans etc. It can also be used to insert and design roads, plateaus for terraces, etc., on contour plans. The add-on is specifically designed for Archicad. and has been available for many versions. Unfortunately, Cigraph now appears to have closed down and/or ceased operation. So, I can’t get a further upgrade.
Could you use Eptar's version? Their one is upto AC25 currently and it looks like you can still buy it off their webiste. The tool looks the same as the Cigraph one and has for many years, but I have no experience with the Eptar one, and have only used the Cigraph one up to AC22.
