SAN RAFAEL -- Autodesk Inc. (NASDAQ: ADSK) on Thursday reported a slight dip in second-quarter revenues and small drop in quarterly earnings.

The maker of design software for the manufacturing, industrial, communications and entertainment industries reported revenues fell 1 percent to $561.7 million in its second quarter of fiscal 2014, compared with $568.7 million a year before.

Sales of the company's architecture, engineering and construction business segments and its product suites did well, increasing 2 percent to 18 percent.

"Growth in these vital areas was offset by mixed contributions from other parts of the business." said Carl Bass, president and chief executive officer

Autodesk expanded its product portfolio with new desktop, cloud and mobile software. But the company's flagship AutoCAD software and its entertainment products both suffered sales declines of 11 percent.

Geographically, Autodesk saw sales gains in the Americas markets and slight declines in Asia Pacific and emerging markets.

Quarterly earnings declined 4.5 percent to $61.7 million, or 27 cents per diluted share, from $64.6 million, or 28 cents a share, a year before.

On Monday, Autodesk said it completed the acquisition of building information modeling (BIM) technology from two United Kingdom-based software companies. From Bestech Systems Ltd., Autodesk picked up Sam, a collection of software modules for loading, analysis and design of small- and medium-span bridges. From Savoy Computing Services Ltd, Autodesk acquired AutoTrack, software for analysis of how vehicles turn (called "swept paths") and design of parking areas and roundabouts.

Terms of those deals weren't disclosed.

Autodesk employs about 7,800 globally, including around 600 in its San Rafael headquarters.

The price of Autodesk's stock at the end of trading Thursday was $36.13 a share, up 1.43 percent, or 51 cents a share.
