再补充一问,如何测量曲线上任意两点之间沿曲线的距离?

You first install an addon named "Curves". Then,
1. in viewport, select curve you want to measure
2. In Curves toolbar, click "Info" tool. The length of curve and other info is displayed on topleft corner of viewport.

1. DraftWB, toggle on Snap bar >Near.
2. DraftWB >Line, draw a line between 2 arbitary points on your curve.
3. DraftWB >Trim, extend above line both ends beyond the curve.
4. PartWB, select both above line and curve, "Boolean Fragments", create a fragmented compound.
5. DraftWB >Downgrade, convert above compound into separate edges.
6. CurveWB >Join, combine needed edges into single curve.
7. CurveWB >Info, select above single curve in viewport.

CurvesWB是纯英文的工作台,命令名都是英文,所以就用英文回答了。 :D

谢谢!FC官网的0.19版有两个版本,之前我在QQ群里问win7 64位该下哪个,群友说是“FreeCAD_0.19.20996_x64_LP_12.1.2_PY3QT5-WinVS2015.7z
”这个,但是我看FreeCADweb.cn给出的0.19的win64位版,是那个win-conda版的,不知道这两个版本有什么区别?
