Parking stalls along curves

[Anonymous]

How are you drafting parking stalls along curves. I still go to LDT.

Hi Sinc,

The compilation worked successfully with the report on the resultant
file size.

None of the other Special linetypes in the AECCLAND.lin use the .SHX
extension when naming the file and I used this as a template to define
my new linetype.

While I was testing this I tried:

*PARKINGBAY, 2.5 x 4.5 parking bay
A,1.25,-0.0,[CIRCLE,AECCLAND,S=4.5,Y=-4.5],1.25

This worked as expected.

However I've adopted your suggestion of adding the SHX extension and it
worked as the attached screen grab shows.

I added another for dealing with bays on the inside of an arc. This
could be used by drawing a conventional arc, then offsetting it inwards
and applying the parkingbay2 linetype to the offset

*PARKINGBAY2, 2.5 x 4.5 for inside of arc parking bay
A,0.00001,-2.5,[MYLINE,AECCLAND.SHX,S=4.5,R=0.0,X=-0.00005,Y=-4.5],-0.00001

Now all we need it for Autodesk to move their linetype ideas from the
1980s to the current century.

A better approach would be to define an alignment style which would work
for all tangents and all arcs where the bays are on the outside of the arc.

With LDT using the >Layout>Parking Stalls menus to create parking, straight, angled, or on a curve, I can zip through parking striping. Wish they had something like it in C3D. It's simple linework and text, but it gets the job done quickly.

Mark,

While I agree with the notion that the old manual way is the best method to insure accuracy its much easier to set points along the arc by distance at the specified parking stall width as a much easer method than by turned angle.

By using Grips - Rotate with Copy, Basepoint and Reference and establishing the first angle by reference. You can then hold down the CTRL key and have each successive copy snap to a multiple of the first angle. That way you can create additional stalls along the arc as fast as you can click.

It's actually much simpler than it sounds written out.

Nicholas,
I agree but I was actually indicating that without CAD, this is the approach I take.
I'm a believer that if there's an easier but accurate way of doing it via linework, all for it.
You can control accuracy to a very high standard with basic ACAD commands/functions if the person driving does it right but most button pushing monkeys don't.
I have to admit that when I first responded, my archaic away (but effective W/O CAD) got mixed in with the "How to do it with CAD" and shouldn't have even chimed in.
Very good post though.

Thanks,
Mark Driver
