  1. I see my community reputation is 3 poor, I do hope I haven't upset anyone. If I have sorry, it was unintentional.


  2. Ah ok, I use illustrator and Photoshop a lot so I generally gravitate to bezier by default. Anyway, I've finally had an evening where I can get to grips with this and I've gone back and started again using the linear drawing tool to establish the balloon shape as you suggested. I think I'm pretty much there now, however something went wrong on a couple of the segments on top. Redoing it should sort that out, I suspect when connecting the segments a couple didn't weld (attached) I just wanted to say thank you again Cerbera for guiding me though this, I'm sure I'm on the home straight now balloon stage 5.c4d
  3. Thanks Cerbera That's exactly what I'm trying to achieve (yours looks great btw) I've followed the first part and created a lath with rotational 'subdivision of 20' and an 'isoparm subdivision of 8'. Setting the spline type (Bezier) to 'close spline', intermediate points to 'uniform' and number to '2' gives me a good approximation of your initial form prior to cutting. I'll pick this up later this evening now, as I need to react to work that has come in, but I just wanted to say thank you again for pointing me in the right direction. I know this is basic stuff but I'm really starting to love this programme and it's really helping me achieve things I couldn't do any other way
  4. Hi All How do you get the segmented ribbed effect in a balloon? I suspect this should be easy but although I've got the basic shape which was deformed from a sphere, attempts to create the curved segmentation has eluded me. Attempts to loop select and scale alternate edges has failed miserably and I'm wondering if I've overlooked a basic technique, or if I should have approached this a different way (with splines for instance) Attached is basic model, any advice or direction gratefully received basic balloon.c4d
  5. I think I've finally got there, finished model (Star cut Pyramid master) attached BUT, and finally, I also have a last question regarding triangles. On the attached hexagon element (based on a cylinder with rotation segments reduced to 6) any attempt to split these triangles has caused me problems, they also read as polygons and even seem to give me no problems under hypernurbs (though I'm not using sb surface modelling on this one) . Anyway, I've blundered on and produced the panel I needed (also attached) but I'm somewhat confused on the triangle issue generally, as it seems to me that any cylinder or circle will undoubtedly contain a high triangle content and therefore cannot be divided. It may seem like an obvious question but my hope is that subdividing triangles is only necessary when subsurface modelling is involved, and doesn't apply outside of that context.

  6. Dear King of Snake Thank you for your help and advice, it really is appreciated. It seems I have very much more to learn on sub surface modelling than even I had imagined, and that's before I even start to do more complicated models. As you say, a lot is undoubtedly down to practice (the same with all things I think) but I'm also wondering if going on a training course may help me avoid some of the pitfalls I'm currently experiencing through my inexperience, or would that be incompetence ;-)? Obviously, I'll follow your kind advice closely and see how I get on. Many thanks once again
  7. Okay folks, I found what was happening Using the sub surface modelling tool I could see where the problems were and the slide tool allowed me to move the points revealing another point underneath, I then deleted that and the connecting edge with the dissolve tool. Onwards and upwards as they say:-)
  8. I've had to put this down for a week while I try and earn some dosh. Now I've come back to it I've found I've hit another couple of snags. I get so far and then come unstuck Hopefully, this is my inexperience showing and these are basic problems that have easy solutions I did try to follow Cerbera's kind advice and model from a quarter section but somehow my first attempt at symmetry wasn't a total success and I had a small but significant gap that grew to a large hole under hypernurbs. This is my first real attempt at sub surface modelling and I'm not all together certain of differences between the tools and what they are all capable of as yet I therefore developed a cunning plan and created everything off a plain and this established the basic shape quickly and easily. The next problem was dividing the triangles to quads which I cut manually according to Cerbera's plan (is there a subdivision command for this ?- I did try something and got 4 triangles) Anyway, to cut to the chase, the 2 attached 2 files have problems With module new version 1c. All the polygons seem okay except for the highlighted corner quad which seems to be an Ngon with 3 polygons, but I can't see that this is any different from 2 of the other similar segments that are quads. I've tried to divide a similar segment into polygons and this has given me 2 triangles though the indicator says they are quads? Yes this has thrown me , so any help would be very gratefully received. I'm hoping it's just fix. Finally the other attempt stalled on extruding the depth (highlighted). I'm thinking this may just be a memory issue as I'm working on an iMac wth 8k of ram and this may not be enough for 3d —I've been thinking of slapping in a couple more modules of ram anyway. Many thanks Kevin Quads 1-1 NO EXTRUDE 1b.c4d module new version 1c.c4d
  9. Hi Cerbera I was going to post my revised effort for your comments, but I'm really stunned that you've not only helped me out with great advice but taken the time to remodel this yourself to show me how it should be done. All I can say is that I'm extremely grateful. My effort has just gone in the bin and I will follow your instructions to the letter. Thank you!
  10. Many thanks Cerbera, I'll go back to the drawing board and attempt to rethink this. Incidentally, I wasn't committed to maintaining triangles, I was just trying to establish what was acceptable or not, and wondering if in some circumstances triangles were. Clearly, they are not! So many thanks for your guidance on this, it is very much appreciated, and heeded .
  11. Hi Folks I'm trying to replicate a plane of objects based on the attached item. The only problem is that I've become aware that it's not good to have triangles in the construction (I was previously aware of N-gons but not triangles) and yet on the inner surfaces of the attached model I can see no way to subdivide them without creating more triangles, besides, I'm essentially aiming to construct a triangle heavy form here so is the absence of triangles critical or does it only apply when using hypernurbs? Suddenly, a thought occurres . Have I gone about constructing this completely the wrong way? I had previously tried to use a pyramid form and knock out the negative shape with a boolean but it had not worked so well as the shallow angles of the inner faces lost definition and blurred into each other, plus, there was no edges to pick up any highlights. To make this I used a cube to create a single corner triangle with a small plateau at the apex and this allowed me to use four sided polygons to define the rise and fall of the outer angle as separate planes. it also allowed a separate quadrangle to split the inner face. I then duplicated this 'quarter' and used the 'bridge' and 'close polygon hole' tool to join them, first making a half, and then duplicating that to make a whole item. I know given the complexity of some modelling this should relatively easy, so have I been excessively long winded in making this and is my inexperience showing? I've tried several times to model this form with polygons over two days and this is my best attempt so far, but is it okay with triangles in it or is it fundamentally flawed?. I should also say I only have prime R10 and 13 at present but I hope to change that soon. I'm finally trying to throw myself into 3d at long last with an eventually aim to model static WW2 aircraft and especially spaceships so I'm also wondering if C4D is the right programme for me as I'm not so much interested in animation or motion graphics as in 3d model making, Special 1b.c4d
  12. No worries, I've approached this in a different way by creating a page of circles in illustrator and then importing them into a relief object, needs a bit of fine tuning but this should do answer.c4d
  13. Hi Folks, I need to create a recessed panel board like the one in the attached jpeg. Should be possible I thought, but I'm an intermittent user, and I've got stuck. Firstly, I created the base board to the correct dimensions as a parametric primitive with a slight fillet to round off the corners. I then thought I'd try creating all the bubbles in forward view to get all the circles in the right place in relation to the board. I then grouped and deleted the circles to create a single null object which I could then use with a boolean to knock out from the base board. It didn't work. Also, even if it had worked, I wouldn't have been able to get the nice fillet effect on the holes so that they reflect light and lift the image panel_bubbles_v2.c4d
