[Closed] Building plan drawing software ,what is good and cheap/free ???

For scale 2D line drawings then draftsight is very good. If you want something a little prettier for visuals then there is SketchUp. Plenty of plugins and online help for both. Both will take a little bit of effort to get the measure of, but both are free. Nothing wrong with old fashioned pen and paper for planning applications if you struggle

for a garage, pen and paper

SketchUp is good if you run the tutorials.  If you can do it fast enough then you can stay within the trial period time for sketch up pro which makes it easier to do nice dimensioned drawings but otherwise the free version works nicely with a bit more work.

Sketchup is brilliant. Loads of tutorials online.

As said above, pen and paper is by far the easiest.  Draw it all out on tracing paper using pencil and a scale ruler.  Then fix another sheet of tracing paper over the top and trace the pencil lines using an ink pen.  If your local planning office only accepts pdfs or the like you can take your drawing to the printers to get it scanned in.  This will be far easier than trying to learn the ins and outs of a computer programme.

PS  The above only applies if you are not completely cack-handed with a pencil and ruler.

Only an architect would suggest drawing it then tracing over the top (with INK?!) To ma it look nice.

If you're going to do it proper.

Set out construction lines with a hard pencil.

Measure from the scale rule using a compass to transfer to paper.

Use a straight edge NOT the scale rule to create straight lines.

Then go over it in a darker pencil.

Or...

Use draughtsite.

Oh it's got to look nice!

I suggested tracing paper as it makes the inevitable changes/ mistakes easier to deal with.  Ink will also show up much better when you get the drawing scanned.

You are dead right about using a straight edge to draw with though.

As for using a compass for transferring measurements I have never done that.  There is no need for super-accuracy on a set of planning drawings.

Obviously the correct answer is to just get a free trial version of Revit...

Some pretty rendering in 3d max.

Job jobbed.

cheers guys , will have a play .
