We design and build corrosion-resistant reinforced concrete tanks and ceramic linings to handle virtually any type of corrosive liquid, and we do it all over the world. Through various divisions we also design and install refractory linings, liquid sulfuric acid production plants and specialty alloy fabrication. All these operations are supported through the central engineering department in Watertown, NY where PowerCADD is the drafting tool of choice. When this product was discontinued we moved to FlexiCAD on the Macintosh platform. We have looked at a lot of programs and nothing we've found can touch PowerCADD for flat-out 2D drafting, short learning curves, ease of use and support.
Nothing beats it for getting great looking drawings out the door quickly.
