I decided to try Draftsight Free for personal, not for profit work, but could not, initially, get it to work. I have, in the past, used AutoCad.
Firstly; it will not install to My desktop, which is running Win XP SP3. I just get an Installer Error 1722 and the installation rolls back. I have never seen this before with any other installation and have tried various suggestions on the web but to no avail. I have posted on another forum but no-one seems interested - https://swym.3ds.com/#community:70/iquestions:29389
Secondly; I have installed, successfully, onto my laptop (i5 Processor, 8Gb RAM, Nvidia graphics). The program runs but I cannot draw using either a mouse or the touchpad. The mouse/touchpad will select menus and select drawing buttons (line, rectangle, circle etc) but I never get past the prompt to specify the start point. The only way I can draw, say, a line is to use the keyboard to input a start and end point vector. The line then appears.
I managed to fix the second fault by forcing Draftsight to run with the Nvidia GeForce GPU rather than the Integrated GPU. However; after I powered down for a few days (I normally just close the lid) it reverted to its old ways and I can now not use it again. I cannot even print from a Window or selection. I have tried forcing the GPU selection to Nvidia and have even uninstalled and re-installed but to no avail. I am not even sure that anyone is interested.
This is not a good start. I had hoped for a lot more than this rather poor start and am just glad that I did not pay for the Pro version. Please help.
I don't know how to solve your installation issue & I have not touched Draftsight specifically, but if it works like the main software there is no freehand draw tool. The next closest thing is the spline tool, which allows you to select multiple points to define a curve. Look in the help menu for a tutorial, may be a good place to start. It will give you some insight to how the software wants you to think & operate.
Similar to learning AutoCAD I have found that not everything in SW is immediately intuitive. Once the software has sufficiently trained you, you will be able to do some powerful things. I hope this helps.
