對(duì)于Flood和Hatch的區(qū)別，在幫助中可以找到：

Flooding recalculates the pour area and recreates all clearances for the current obstacles within the pour outline, observing clearance rules. Hatching refills (with hatch lines) existing pour polygons for the current session; it does not recalculate the pour area. Each time you open a design file, you must flood or hatch the design; this information is not saved. In most cases, you can simply Hatch. Use Flood if you make changes to the copper pour polygon that could create clearance violations or if you change clearance rules.

Flooding會(huì)重新計(jì)算灌注區(qū)域并重新計(jì)算當(dāng)前填灌區(qū)域的外形線內(nèi)障礙的所有間距，和一些注意的間距規(guī)則。Hatching則用來（用填充線）重新填充當(dāng)前會(huì)話內(nèi)已經(jīng)存在的填灌多邊形，而并不會(huì)重新計(jì)算填充填灌區(qū)域。每次打開一個(gè)設(shè)計(jì)文件時(shí)，你應(yīng)當(dāng)對(duì)這個(gè)設(shè)計(jì)進(jìn)行flood或hatch；這些信息是不保存的。大情況下，你只要簡單的Hatch一下就夠了。當(dāng)你對(duì)灌銅多邊形的修改會(huì)引起規(guī)則沖突時(shí)，或當(dāng)你修改了間距規(guī)則時(shí)，請(qǐng)使用flood。
