Adobe Illustrator is used to help make drawings look good but not make them. It is easy to add color or texture but it is hard to actually make the drawings in it. I would recommend using other software to make the lines for plans and sections and using Adobe Illustrator to make it look good.
If you're in a situation where you're regularly creating content for a website, social media page, or even printed materials, Pixlr is a great option! It allows you to create something simple from scratch (with just a solid background and text) or something more complex (with multiple pictures, layers, fonts, shadowing, etc.). It's our go-to method for creating content. If you're someone who isn't very tech savvy, the learning curve for using Pixlr effectively could be discouraging. The interface is intuitive, but there's a lot to it
While Adobe Illustrator CC is one of the only true design software out there, it really stands heads above the other products. It's clean UI and menu structure is easy to navigate.
There's a bit of a learning curve to this software vs other similar tools that can take some time to learn and get familiar with but the amount of functionality that Adobe Illustrator CC offers is quite large compared to simpler tools.
I normally already know how to do whatever I'm trying out, but the documentation (as well as a simple Google search) makes any question quick to resolve. The Adobe boards themselves are a fantastic resource, especially for resolving questions between new programs and iterative releases.
They complement each other, each with its own specific characteristics, but within a marketing sector, an experienced designer knows that the use of these tools in sets makes all the difference. It is possible to combine their uses and create really relevant materials that will bring a great return to the company and in the dissemination of arts with superior quality to the competitors
Canva is a similar program using for creating content. I've tried out their suite as well but always end up coming back to Pixlr because of ease of use, and my familiarity with the product. They continue to make upgrades to the product and have always had what we feel we need to make top-notch looking graphics for our organization.
