![]() ![]() I usually discover lots of bugs during that: missing, redundant or overlapping tabs, missing parts, inconvenient cut/fold lines, inaccuracies caused by paper thickness, errors in markup etc. But I have very little experience with these programs. Another interesting combination is Metasequoia + Pepakura designer. #Deleting faces in pepakura designer for free#Blender and Sketchup are for free and can unfold via plugins and scripts. If you are looking for a program for both modelling and unfolding, I'd recommend Rhino - it is said to be in all ways better than AutoCAD and much less expensive. to compensate paper thickness) and choose what faces to add or skip. Quite tedious, but with total control over everything, possibility to add or delete something here and there (e.g. Unfolded parts (in vector environment) have to be drawn, placed on pages, given tabs and so on.ĪutoCAD has no built-in function for this (or at least I don't know about it), so I do it manually: I copy edges of a solid and then unfold it face by face using "3D rotate" and "align". ![]() In a parametric editor, you just rewrite a coordinate. Snap-to-something is a very useful utility too, there are many options: snap to endpoint, midpoint, centrepoint of circle, perpendicular to something, parallel to something and so on.ĭisadvantage is that the basic AutoCAD is not parametric, so if you want for example move a hole, you must manually fill it and then drill at the new location. Of course, besides solids, you also need lines, curves and circles. Intersection shapes are determined by boolean operations. I usually create solid by extrusion or rotation, then slice them down to the final shape. I usually start with pinning the orthos in the modelling space, align positions and scales and then use them as a direct reference. #Deleting faces in pepakura designer windows#I work in an old student version of AutoCAD 2002 on even older computer (166 MHz processor, about 90 MB of RAM, several GB disk and Windows 98), which runs it quite smoothly. are out of my skills without 3D solid modeling. Virtual 3D modelįor simple things I use just a cross-section as a reference or draw unfolded parts directly, but complex shapes, intersections etc. The drawings are somehow imported into the computer and next phase begins: 2. Paper accepts anything, doesn't need exact dimensions or coordinates and one has better idea about the proportions than on a screen. My favourite solution is to take a pencil and draft ortho views on a paper, with no ruler, compass or scale. There are also less-ideal situations when we have no more than a few pictures, photos, screenshots or comic panels and a slight idea about the overall size (which is quite frequent with sci-fi subjects). Or when the subject is so small that you can measure it with a caliper. The best is to have three(or more)view orthographic drawings, well-detailed and in exact scale. The basic necessity - you must exactly know what you want to design, otherwise it usually doesn't end too well. ![]()
