231 forum posts | Extrusion works on the area between two boundaries, as noted. Couple of additional points worth mentioning, though. The first is that you can select more than one area (hold down "shift" while clicking on regions) to extrude at the same time. This means that even if there seem to be extraneous lines crossing the area you want to extrude which seems to divide the area you want, you can just click on both sides and pick both. Which then leads to the point that a sketch is not a "drawing". You absolutely do not need to tidy odd lines and so on in a sketch; a sketch is a means to an end and once used (in synchronous mode) will be ignored thereafter. So, for example, if you want to extrude a rectangle that has a circular arc cut out of one corner, you could carefully draw an arc, trim out the excess lines, and extrude the remaining shape as desired. Or you can just draw a circle centred on the corner of the rectangle and just select the area you want to extrude and ignore all the additional lines. Saves time although it upsets the traditional draughtsman! But this is a sketch - not a finished drawing... SOD has also mentioned reasons for using the hole tool rather than extruding. This just emphasises the fact that you can often achieve the same end by different means. Creating a circle in a sketch and then extruding is great for a hole that goes right through the part, and is also useful for non-circular holes. However, the hole tool is really useful for counterbores/countersinks/part-depth holes - or holes that go through more than one part in an assembly. Edited By Nealeb on 24/08/2022 22:22:32 |
