Troubleshooting / help exporting to dwg and PRESERVING block structure

« on: July 29, 2011, 07:46:30 AM »

when i export from rhino to dwg, in 4 or 5, my blocks lose their link between instances. I thought it was possible to keep this intact. Can anyone help?

Ask for help / question about worksessions

« on: July 15, 2009, 02:10:36 PM »

Does anyone out there use worksessions?

I am working on a really huge project which I have had to break out into separate files and recombine in a worksession file. I am more used to using xrefs in autocad and I really would like a way for the files which have been referenced to be referenced using a relative path and not a fixed one. Everytime I move my files the whole thing breaks down and it seems like there should be a way to move from computer to computer with the files and have it still work.

Any ideas?

Ask for help / Re: cinching together trimmed surface edges

« on: July 03, 2009, 11:43:17 AM »

i think the networksrf route is more sppropriate since this is a bit of landscape and I'm not sure how the patch command would be able to know what's happening over the breadth of the surface in order to recreate it. So, if I go the ntwrksrf route, I could first take regular sections in both directions and then make sure the ends of the curves hit that base regular surface before running the command? is there something you can think of tht coud take alot of curves and force thiem to hit an edge? this would be really useful but also complicated - end points would need to move in two directions along the plane of the section.

thanks so much for the help

Ask for help / cinching together trimmed surface edges

« on: July 02, 2009, 12:50:41 PM »

Hi

I have no idea how to do what I need to do - take two surfaces with matching edges that are not together and bring them in alignment. In overhead or plan view they metch up perfectly but in elevation they are at different heights and not in a constant way. if I could I would go around and adjust each point individually but since they are trimmed surfaces it seems like it's impossible to edit the edge curves individually...any ideas on how to fix this problem?

thanks so much in advance

i think i may have finally found a solution, here's hoping it actually works...

i'll try that, but it doesnt sound exactly right. I get how the intersection will get the cut through the objects but how do you get the items seen in elevation? considering how many architects use this software it's amazing that there isn't a clean solution.

Hi
I am looking at ideal ways to make a section from a rhino 3d model. Ideally there would be something like sketchup's section plane tool or formz's clip hither yon which both not only clip the model but also identify the surfaces being sliced. Is there anything like this for rhino?

Are my only options really just to trim half the model away? Is that how architects create their sections?

I am open to all options - even plugins.

Thanks for the advice, in advance.

Ask for help / Re: help with simple modeling operation

« on: May 21, 2009, 01:00:17 PM »

yeah, I think a screenshot is in order to, but since I have moved past the problem - I think - I m not going to go back and recreate it. The solution was in the Sweep1 command and using the road like style. I believe this solves the problem. I should have mentioned that I Was hoping to keep everything in Grasshopper - I don't know if you use it too. The prblem now is ensuring that all m section curves are oriented the same way - right now the sections are justdumb retangles but it's important that the longer direction is parallel with the xy plane - and I can't seem to make them all the same...any ideas?

I 'baked' the current state of the work from GH and you can see a couple of cases where the section is rotated perpendicular to its proper orientation. I want to stay in GH - I don't want to manually go around and rotate each section individually...

thanks

i

I am having a problem with a basic modeling operation . I have a series of curved paths - that curve in all directions - and I would like to sweep a rectangular section across them but maintain their orientation along the path's length. More concretely, I want the horizontal length to remain parallel with the xy plane of the model so that this surface could represent a path or walkable surface.

I have played around with the various ways of producing perpendicular planes to the curves or frames and then adding an "align planes" component but invariably there are always some planes that are rotated 90 degrees to the others. This is the most troubling part of the modeling issue, but I am also wondering if I should be sweeping along a path or placing the section at intervals and then lofting.

I realise this might seem really elementary...but I'm not sure how to deal with it.

Thanks so much in advance.

Ask for help / Re: converting imported geometry from autocad into curves???

« on: May 08, 2009, 01:31:48 PM »

looks like it might be a problem with the underlying autocad geometry...it's something called a 3d face and it sounds pretty troublesome - can't explode it in acad either

i can only explode down to something called a mesh face - even though they appear as lines

the silhouette operation didn't work either...it would not accept the objects as input...any other ideas?

Hi

I want to do something that seem really simple - i have linework in autocad that I want to bring into rhino but when it comes in it arrives as polygonal mesh elements. I have looked everywhere for a way to convert this some how to polylines or curves but I can't find anything...

any ideas? seems like it should be really simple...
thanks!

Ask for help / Re: is there a faster way to add missing mesh faces?

« on: April 30, 2009, 09:36:08 AM »

i manually closed the naked edges at the interior of the model...that seems to be ok but then when I changed to rendered mode I noticed there are these funny bits that weren't there before. I have attached an immage that hopefully shows what I'm talking about. They look like artefacts and they have a king of gradient shading instead of a flat single colour. This was also happening when I tried to connect this mesh to sides I had created for it - what do they mean? I presume that there's something wrong

Also, I culled all degenerate faces and duplicate faces and all the stuff you are supposed to do after a check mesh but there are still problems...any ideas?

ok. thanks for that advice. I have tried fill mesh holes but since my mesh is more surface than solid - it adds faces where there shouldn't be any - on the underside. I have tried to make the things more solid-like but since there are so many triangles the edges are hard to make - any advice?

this is a site model with a huge number of triangular faces

« on: April 29, 2009, 11:02:59 AM »

I have been struggling with a massive landscape mesh that is missing many triangular faces all over the place. I am looking for a much faster way to add these needed faces instead of moving progressively from one to the next clicking first one edge and then the next -does anyone know of a good way to do this?
