Lentezza Posted February 27, 2013 Share Posted February 27, 2013 (edited) Hello, I have the following situation to resolve: I am in the process of drawing a corner bench which later on I will produce from solid wood. I am at the point of drawing the corner piece of the seating surface. I´d like to this with sweeping and slicing the profile of the seating surface. Because this way I will have the the correct edge profile on the very tip of the corner piece on the inside corner of the seating. Benchcorner 123.dwg To make it as simple as possible I tried using the green extruded part for slicing the swept part of the seating surface (brown). But it did not work.... With the SLICE command it seems I can´t choose such an object as the slicing one... So instead I put the green planar surfaces. Did not work either... I am sorry, this seems to be a very basic question. Still: help very welcome!! If I have been missing a thread or a tutorial that will be answering my question please let me know.

ReMark Posted February 27, 2013 Share Posted February 27, 2013 All you need is a profile, a path and either sweep or extrude it. Quote Link to comment Share on other sites More sharing options...

f700es Posted February 28, 2013 Share Posted February 28, 2013 I moved your thread to the 3D section Quote Link to comment Share on other sites More sharing options...
the downing effect Posted February 28, 2013 Share Posted February 28, 2013 above would be the best way to go, but with what you have already just make the surface into a solid and use the intersect command. Quote Link to comment Share on other sites More sharing options...

togores Posted February 28, 2013 Share Posted February 28, 2013 You can try the two solid editing commands I posted in the thread http://www.cadtutor.net/forum/showthread.php?77186-New-3DSolid-TRIM-and-SPLIT-commands. They are a great addition to the standard 3dsolid editing commands. AutoCAD does not include them, but they are included in Sketchup 8. They are two of the sample programs from my book "AutoCAD expert's Visual LISP" Quote Link to comment Share on other sites More sharing options...
ReMark Posted February 28, 2013 Share Posted February 28, 2013 Could you demonstrate the use of SPLIT using the OP's drawing? What would the SPLIT command accomplish differently than what I show in my posted image? Thanks. Quote Link to comment Share on other sites More sharing options...
ReMark Posted February 28, 2013 Share Posted February 28, 2013 I think it is this corner that is going to be problematic given the profile of the bench seat. Quote Link to comment Share on other sites More sharing options...
ReMark Posted February 28, 2013 Share Posted February 28, 2013 Strange. No responses from either poster with a different idea. OK...well here is what I've come up with as being the problem: The two circled areas indicate areas where material was removed by staying true to the profile. I don't see anyone making this bench seat going through all that trouble. So, how would it be done in real life? I'd like to know for my own education. Thanks.

ReMark Posted February 28, 2013 Share Posted February 28, 2013 I am not a carpenter or a furniture maker but if I were building this bench seat this is how I would create the inside corner.

Lentezza Posted February 28, 2013 Author Share Posted February 28, 2013 Hello, thanks to everybody, especially ReMark! Just got back to my computer. (I started the thread last night before going to bed...) I´ll have a close look to your posts now and will be back later. Quote Link to comment Share on other sites More sharing options...
Lentezza Posted February 28, 2013 Author Share Posted February 28, 2013 Thank you once again ReMark, the obvious solution was the good one!!! Sweep is really a great tool!! No slicing necessary really...Thanks to everybody else for alternative suggestions anyway! Concerning the realization in solid wood...: explaining this in english is even harder than trying to describe CAD-problems... For esthetic concern (imho) and also keeping in mind the swelling and shrinking movements of the boards, it is better to let the boards "follow the sweeping path". This obviously makes the corner piece a separate one. If you take the drawing I attached for the SLICE-question you can easily understand how I will produce the profile for the tip of that piece: first I´ll produce a square part of board like the brown object in the drawing. Before I´ll cut the shape of the corner piece from it, I´ll do the fillet of the edge with a router in the region of the tip. Considering the way I do the construction with the corner piece being separate your suggested above solution thus obviously is much harder to realize. Hope my above explanation can be followed....

ReMark Posted February 28, 2013 Share Posted February 28, 2013 When I see your posted image I'll understand better. If it were my bench I'd keep it simple so even a caveman like me could do it! Would it be easier to do if the corner did not meet at a point? Quote Link to comment Share on other sites More sharing options...
ReMark Posted February 28, 2013 Share Posted February 28, 2013 A radius applied to the corner would give this result. Quote Link to comment Share on other sites More sharing options...
togores Posted February 28, 2013 Share Posted February 28, 2013 Could you demonstrate the use of SPLIT using the OP's drawing? What would the SPLIT command accomplish differently than what I show in my posted image? Thanks. I hadn't examined the drawing. No need for anything special, just the regular SLICE command. Just take care that ths surface goes beyond the solid's extents. I attach the sliced drawing. Benchcorner 123.dwg Quote Link to comment Share on other sites More sharing options...

the downing effect Posted March 1, 2013 Share Posted March 1, 2013 Pretty much the same result, but he was already right here. I guess either way it only takes a few minutes. Benchcorner.dwg Quote Link to comment Share on other sites More sharing options...
Lentezza Posted March 13, 2013 Author Share Posted March 13, 2013 Thanx to everybody once again. I have been busy changing computers..... Guess I´ll have to work a bit more on my basic 3d-skills...... Quote Link to comment Share on other sites More sharing options...
