    Courragated pipe

    in Solids Modeling

    Posted

    No it worked, as shown in the image I attached. The only difference is I extruded two circles and fileted the edges rather than sweeping the shape. That's why mine is solid inside.

    So no, it's not that I didn't get results, I just wondered if there was a more poly-efficient way to do it as creating potentially hundreds of copies of the segment seemed intensive.

    Thanks for your post. Got an interesting conversation on the forums if nothing else.

    Thanks Mike

    I am looking for an actual modeling solution. I could get a good effect with displacement maps (although it takes forever to render) but I'm trying to find an actual geometry method.

    Thanks for the suggestion

    Hello all:

    I'm trying to make a corrugated pipe like the ABS landscaping drain pipe you see everywhere. I'd like it to be able to curve along a NURBS path so the pipe can bend in multiple directions at once. I messed around with the Chain extrude (does anybody use that tool?) and was able to make it work along straight lengths but despite having Bezier options in the mode bar, it only seems to make straight runs with angular bends.

    The best I could come up with was modeling one segment and then using a NURBS as a path for a "Duplicate along a path" that seemed to work ok but it made dozens of replications of the shape to do it.

    Is there a better way?

    Thanks

    Section Viewport settings?

    in General Discussion

    Thanks Jim

    In a fresh document I am able to get it to stick with Limited By Selection Length. But I still can't get the Fixed length to work with the auto-inserting drawing labels. I changes the settings in the OIP before inserting one--like you'd do with attributes--and I changed it at different times and ways after being inserted. I can't get that one to stick. It's not a huge issue, I just am pretty sure it was not that way in the past.

    Thanks

    Section Viewport settings?

    in General Discussion

    Posted · Edited by SeanOSkea

    I hope this is an easy one.

    Is there a preference settings for the default settings of viewports? In the past I seem to remember "Limited by Selection Length" Being the default setting. And I thought Depth range could be set by how far you extended the last leg of the section cut line.

    Now each time I want to crop I need to go into the OIP then Advanced Properties... and change the setting.

    Same thing with Line Length Mode for Drawing Label objects being defaulted to "auto fit."

    I'd love to get these back to my old settings but I can't figure out how.

    Thanks

    Displacement maps

    Thank you!

    This is the most clear and conclusive answer I've ever received from a forum post! Of course that's what's going on. I can't believe I didn't see that. In C4D I just selected the one polygon face to apply the texture to, that's why it didn't happen there. And the funny rectangle test (I realize I posted the wrong image)That's why the black rectangle was slightly shorter than the white--it was shorter by the thickness of the extrusion.

    Thanks for the bit-depth tip too. However, when I tried to recreate the problem for Jim, and couldn't--I must have made a slightly thicker extrusion--it looked fine. So I think the washboard was also a result of the double sided texture.

    Thanks to both of you

    Displacement maps

    in Rendering

    Posted · Edited by SeanOSkea

    I’m trying to get a handle on displacement maps. I watched the recent VW youtube video on Maxwell render files and downloaded a bunch to play with. I even got the shingles that Jim recommended in an earlier post. I have very strange results.

    In VW (very high, 1” 12”sq) there was a strange corrugation in the image and a V-shaped valley in the middle of the shingle. I used the same files in c4d (10 subs) and received the expected result. I tried many setting variations in VW and could not get the same results as the c4d render.

    So I decided to do some test files. Went into PS, filled with 50% grey. Put an almost white rectangle next to an almost black rectangle. In c4d they rendered as you would expect with the white rectangle extruding and the black receding. In VW both rectangles extruded. The only difference was a small valley around the edge of the black rectangle. I put the d-map in the color channel for reference.

    I’m hoping I’m doing something silly.

    Hmm... all the attempts to select it failed. Until I started messing with layers and classes to see if it was somewhere else.

    Switching from Grey/Snap to Show/snap/mod Layers caused it to vanish. However I only have the 1 default Design Layer 1.

    I know am a "Greenhorn" here and I sound like a noob in these posts, but trust me I've been using and teaching this software for a decade. There's something going on here.

    Thanks

    OK Jim. Its happened again. I was just playing around with some of the new spotlight stuff and made a ladder stuck a few instruments on it and then entered a rotation of 90 in the OI rotate field. I did an undo and a phantom light stayed behind in the position one of the lights was in in the rotation. I can't select it. Just like my escutcheon plate in my other file (that was the mystery object). I tried to attach the file but the file manager says its larger than 2MB. Is there another way I can get it to you?

    Disapearing textures

    in Rendering

    Dave:

    No it reverts to the attribute color--white if I haven't done anything to it or whatever fill color it was if I had assigned a color.

    It happens in all (well both--I can't say all) modes. I usually notice it as I'm examining a Final or custom RW render then I notice something white that should have a texture. It's the same in OGL. This last time it even affected two legs of a chair that I had converted into a symbol. I had to edit the 3d of the symbol to fix the two legs, while all other parts of the chair with the same texture were fine.

    The only problem I've had between OGL and RW was a few versions back (12?) where images in textures would be scaled properly in RW but 2x as big in OGL. If I reduced the ratio to make the OGL look right then the final render would show the image 1/2 sized.

    But I haven't seen that in a while and even then it was extremely rare.

    I think this new thing has only happened in 15 but it's happened several times since September. It only takes a few minutes to fix...if I catch it before I launch a 20-minute FQ render.

    Thanks Jim,

    I had given up assuming the file was corrupted. But as I’ve put a lot of work into it I was determined to hunt it down and kill it. I finally succeeded. It seems like the object’s actual position and it’s “visual position” in the document somehow got separated. I was able to select it by dragging a box around a completely different part of the drawing—empty space. Then I immediately cut and pasted into a new layer. Once there it behaved perfectly normally. I deleted and moved on. I don’t know, this is one for the Enterprise crew. I’m assuming it was some kind of glitch. Thanks anyway.

    I have an object in my model that is completely un-selectable. It is a tapered extrude that got left behind when I rotated the rest of the object that it was part of and I missed it in my selection.

    Now it is lost on some parallel universe. I can’t force select or Ctr-drag select. Nothing short of Ctr-A will select it. I made a copy of the file and, one-by-one deleted every other object in the model to see if it had been accidently grouped with something—nope, there is was all by itself on an empty layer. If I select-all and delete, it goes away. Nothing short of that works. When it was all by itself, I did a Crt-A and the OI said it was a None/None class/layer. Nothing special. I would ignore it except the Viewport sees it too and draws it. It also pops in and out of existence when scrolling in top/plan.

    Any ideas anybody?

    Disapearing textures

    in Rendering

    Posted

    I’m having a minor but annoying problem with 15. Textures keep disappearing from objects. I will create or import a texture, apply it to a number of objects and go on my way. Later (I assume after reopening the file) I’ll notice that random objects will not display their texture. According to the OI Render-tab the texture is still applied to the object, and other objects in the same scene will be displaying the same texture, but nothing short of re-applying the texture will make the tex display properly on the effected objects. When it happens it will strike 3 or 4 objects at the same time—but again not all the objs with that texture. I can’t say for sure but it seems to affect ext-along-path objs more frequently.

    Any thoughts anybody?

    Horizontal section cuts?

    in General Discussion

    Posted

    I was excited to use the Create Section Viewport to make quick groundplans for theatrical scenic designs. I was disappointed to see this option is only available on the sides of the clip cube. The viewport section cut also does not allow for horizontal cuts.

    Scenic ground plans are basically section cuts at 6? above the stage floor (actor?s head height) cutting through scenery and theater architecture. If I could Create Section Viewport from the top of the clip cube, it would be exactly what I?ve been wishing for, for several versions. Short of rotating the whole model 90, is there a way to create a viewport from a horizontal cutting plane at Z+6??

    Thanks

    Demo of 15 constently crashing

    in General Discussion

    Posted

    I eagerly downloaded the Trial of 2015 this morning. I haven't quit a session yet. After opening a file form my current version (2013) I'll play around for a bit, checking the new features only to have it crash. This has happened 6 or 7 times in a row. Seems to happen when I'm in Open GL. I'm a bit hesitant to drop $1500 for an upgrade if I can't get 10 minutes of work done.

    I hope there is an easy fix here.
