  We used the data from the Spitzer Legacy Infrared Mid-Plane Survey
Extraordinaire (GLIMPSE) to investigate the mid-infrared (MIR) properties of
planetary nebulae (PNs) and PN candidates. In previous studies of GLIMPSE I& II
data, we have shown that these MIR data are very useful in distinguishing PNs
from other emission-line objects. In the present paper, we focus on the PNs in
the field of the GLIMPSE 3D survey, which has a more extensive latitude
coverage. We found a total of 90 Macquarie-AAO-Strasbourg (MASH) and MASH II
PNs and 101 known PNs to have visible MIR counterparts in the GLIMPSE 3D survey
area. The images and photometry of these PNs are presented. Combining the
derived IRAC photometry at 3.6, 4.5, 5.8, 8.0 um with the existing photometric
measurements from other infrared catalogs, we are able to construct spectral
energy distributions (SEDs) of these PNs. Among the most notable objects in
this survey is the PN M1-41, whose GLIMPSE 3D image reveals a large bipolar
structure of more than 3 arcmin in extent.
