AutoCAD 2013 :: Working In 3D Modeling Space Using Parametric Linear
Nov 15, 2012
I have teached myself working with autocad version 2004 so maybe its not the right way of drawing but I draw 3D objects using solids!
In the past I could take or put dimensions on this solids to print and pass on to colleagues but on our new 2013 version I seem incapable of doing this I can not select a point on a solid and continuously get the message invalid point!!!
working in 3D modeling space using parametric linear! what am I doing wrong? or is it an setting that I need to change?

I often create animations for technology companies, and they give me models that were created in programs like alias, rhino, AutoCAD, or solid works. They export for me in IGES, or STEP, and the models, while amazingly intricate, are too much for Maya on my 24GB RAM 12-core machine to take. They take upwards of 20 minutes just to open.
I want to convert these to ploys and generally make them easier to work with. What are my options for making these manageable, and still look good when they render. The flat edges and services are fairly easy to convert, it's the rounded bevels that don't look so good if I convert everything to Polys all at once. And there are usually hundreds of curved surfaces to convert, so doing them one at a time is far too cumbersome to be effective.
Also, how would I go about taking surfaces for objects in joining them together to create a complete object made of Polys? For example, a small part may be made of 35 difference parametric surfaces in solid works, and exports as that in IGES, so when I imported into Maya, it really should be just one object made of Polys.
need to convert parametric cad objects to poly to make them manageable and to make renders faster.

I am trying to "trace" the shape of a circle on a 3d box using the cut tool to create some edges..using a 2d "circle" as a template...it will NOT create the edges!!..all the tool shows is a "dotted" line but doesn't create the edge or the verts for it.I tried ortho views and perspective along with left/right.

I have a problem. When I use parametric dimensions in my existing drawing the dimension lines and arrows are there but the numbers are invisible. I can't see them. I have searched over much of the dimension style manager dialogue box and I can't find a setting that would change this (but I could have missed something). When I open a new drawing and draw a rectangle and add parametric dimensions they are visible and there doesn't seem to be a problem. What the hell is going on? (I have not used paramentric dimensions until just recently.) I am first going to the top view, with the z axis perpendicular to the page, before adding the parametric dimensions (in case that makes a difference).
I previously had a problem wherein an entire drawing I had drawn suddenly became invisible, except when the pointer was in certain places and then it was temporarily visible. But that problem was solved when I just shut down the program and computer and then restarted it all.

I'm trying to switch over to a gamma/linear color space workflow. 3dsmax and multiple blogs state that displacement, normal bumps, and bump maps should be noted in 3dsmax as gamma 1.0. All other maps (diffuse maps, etc) should be noted as gamma 2.2 (or whatever gamma you created them in) so 3dsmax can properly convert them to gamma 1.0 during its math calculations.
This is all fine. It makes sense that if you make a color bitmap in Photoshop, what you see on screen is being created/tweaked at gamma 2.2 and needs to be converted in 3dsmax (corrected down to gamma 1.0). 3dsmax notes that Mudbox and certain other software produce normal and displacement maps already in gamma 1.0 so these do not need to be corrected. Similarly, black and white bitmaps used for bump and displacement also should be noted as 1.0, not 2.2 (not adjusted down to 1.0).
Questions:
1) If I create a normal bump map in Photoshop (plugin), is that going to be gamma 1.0 or 2.2?
1b) Does it depend on which format I save it in? For example, jpgs default to gamma 2.2 (no gamma listed), while targas can note inside the file which gamma they use.
1c) If, in Photoshop, I simply open a normal map created in Mudbox (made and saved at gamma 1.0 automatically), resize it in Photoshop, and resave it as a jpg, have I inadvertently converted it to a gamma 2.2 image?
2) If I make a grayscale bump/displacement bitmap in Photoshop, it does not need to be adjusted from gamma 2.2 (but is "already" gamma 1.0). Why then would I note that same grayscale bitmap, created in Photoshop, as gamma 2.2 if it's used in any other slot (reflection, roughness, cutout, glossiness, etc)? By using Photoshop, aren't I looking at gamma 2.2 adjusted grayscale values on the screen when I create the grayscale image?
2b) Conversely, are displacement/ normal/ bump maps made in Mudbox only gamma 1.0 if they are saved in a non-jpg format?

I am currently designing oil pipe gauges, So the sizes are all out of a standard and therefore I can use the parametric manger, and create parameters match them with the right dimension and we have our drawing.
Now for each gauge, I am going through creating a separate drawing and typing in the selected data for that gauge, is there any way to link parametrics manager to look up from a table for the selected data, instead of me typing through each separate gauge data.

I have to repeat a circle an even number of times across a 597" linear space. The circles need to be approx 24" apart, but evenly spaced. How can I do this without having to manually calculate the spacing and the # of circles required?

I'm wondering if any effort will ever be made to fix the issues surrounding the "Linear Working Units" preference in Maya.
There are many persistent bugs surrounding the use of this feature. Locators change size, NURBS tools go haywire, etc.
Just today I discovered another very bizarre problem. With Linear Working Units set to centimeters (the default), then ordinary, normalized NURBS curves have a U parameter space from zero to one. It's axiomatic that the U parameter is the distance along the curve, measured not in linear units, but expressed as a decimal of the total length. I.E. halfway along the path, the U Value is 0.5, regardless of the actual length of the curve.
So that all makes perfect sense. But if we change the Linear Working Units to anything other than centimeters, everything goes to hell. With Linear Working Units set to Feet, then a normalized NURBS curve has a U parameter space from zero to 0.033. This can be clearly seen if attaching a Motion Path to a NURBS curve. The keyframe at the end of the curve shows a U Value of 0.033.
Obviously, a centimeter is 0.033 of a foot. But what does that have to do with NURBS parameter space? Absolutely nothing. Changing the working units should have no effect on the readout of the U Value.
I'm hoping the developers 1) know about this, 2) care, and 3) have the freedom to do something about it. Because this is, to put it bluntly, crazy-making. I know that the Linear Working Units feature was bolted on to an existing unitless system, so there are bound to be problems. But why on earth are NURBS parametric values affected by the choice of working units?

I feel like I have a vague memory of once learning how to click on an object in a viewport and being able to click a button or use a command to switch that object to paper space (so that it appears the same size). I'm trying to avoid having to go through the steps to scale down the object once I get it in paper space).

I have several viewports rotated in paper space. When i set them to let say 1:100 scale go to paper space and then click into viewport it comes back to zoom extends of model space and i have to set it all up again and rotate it.
Second problem is that I've created wipeout in model space when i go to layout (paper space) ti looks just how i want it.
When I go to preview or plot it doesn't recognise any wipeouts?

I'm trying to import a drawing from a dwt file into a drawing as a new layout. This would be perfect if the model space objects associated with this dwt file would import as well.

Today, all of a sudden, two of my most used functions—holding down the space bar to move the image around and holding down CMD-space bar to zoom—just up and quit on me (I do like the "Scrubby" but it took a little getting used to. It's very touch screen-esque).
I did all of the normal trouble shooting such as deleting the prefs, relaunching, restarting, etc. Nothing. The functions work fine in the other CS5 programs.
I checked through all of the prefs thinking that perhaps I accidentally changed something but I couldn't find anything. If all else fails, I'll do an uninstall/reinstall but only as a last resort.
I did notice that Adobe finally fixed the Distort (in Full Screen Mode) bug that was killing me in CS4.

[URL] Bug is where the Hand move (by holding down Space bar and dragging) stops working. Issue appears to be a conflict with web browsers.
This bug is still present in Photoshop version 12.1 (CS 5). I don't use Firefox, I use Safari and Chrome. Quitting Safari did not fix the problem. Quitting Chrome DID fix the problem.

I notice as I zoom in and out of the 3D modeling space that the background and grid colors fade from light to dark.
Is there a way to control the fading when zooming to keep the background and grid from becoming too light and illegible ?

I'm a beginner/intermediate level 3ds max user and I've recently starting to model what I love the most - sci-fi stuff, more specifically, space ships. So, I've been browsing the net looking for models done..Now, there's one very specific question in mind: does a ship (say, a very creative and complex concept) has to be one single object, or can it be a group of linked objects? Notice that I have in mind game development. URL....

In sub object mode, I have some vertex selected, I would like to set this vertex to a specific position in space.
For exemple, In the picture attached, I want that each 4 vertex set to 0 in x position in one command (I don't want set to 0 individually each vertex).

For some reason, I cannot dimension in paper space. i beleive I have set everything up correctly, but the dimensions in paper space are not correct.
See attachement.
The circle is 12" in diameter, but if the viewport is 1:2 scale, the diminsion in paper space shows 6". what do i need to do to correct this?

I have a model rigged with The Setup Machine and The Face Machine and a single material is applied to each of them. Not sure if the above is relevant, but when I tested this in a clean scene with just a sphere, everything was fine.
I then select a few faces and apply a new material to those faces. I smooth the mesh and the UVs are smoothed and the different materials appear where they should be. If I set the divisions on the polySmoothFace node to 2 or more the materials seem randomly placed across the mesh. The Uvs however, are smoothed correctly. So I then have to reassign the materials to the correct faces.
If I do one smooth mesh, then another separate smooth mesh, the materials are placed correctly.
Is this a bug or do you think something is wrong with my setup?

I am not an AutoCad user but I've got an assignment that would go better if I understood a little bit about how interior designers choose colors in AutoCad.I know there are the three tabbed choices - ACI, "True Colors" and Books.My top questions are:
1) does the user choose an RGB "working space" like one would do in Photoshop or Illustrator (in other words, decide if they want to work in sRGB or perhaps Adobe RGB or ProPhoto RGB). Or is there just one possible RGB - in which case, I guess it must be sRGB.
2) is the data for making up the ACI know, so that one can translate ACI colors to their RGB equivalents?
3) I now that with the HSL model you are picking %s of hue, saturation, and lightness....but what is setting the parameters for what is possible here? Is the HSL just a picker that is overlayed on RGB?

Civil 3d 2012 SP2 - When using "Align Space" from the layout Panel of the Express Tools ribbon, I am not able to align the viewport correctly. It seems to be working backwards. I am trying to orient a viewport to something other than a cardinal direction, but for the sake of clarity, I will use an example using cardinal directions. If I am trying to orient the viewport so that North is at the right side of the page, when prompted for the model space alignment I select a line that goes from south to north in model space. When prompted for the paper space alignment, I select a line that goes from left to right. I would expect that north would end up on the right side, but it is on the left side. When experimenting a little, it seems like it is using the model space alignment as the paper space alignment and the paper space alignment for the model space alignment.

I am new to Autocad, Everything was working fine until now...I can access a command via command line or menu or toolbar just fine, but although the command line prompts are working, the model space is not showing my lines, circles, rectangles etc. Nothing new is appearing on my model space. I am not sure what I accidentally changed. This is only true in this particular file, my other files are working fine.

I have this heavy issue, i can't send to back a line, an object or a hatch under other lines. In 2012 i used this feature a lot but in 2013 it's not working very much, maybe 1 time out of 10 and i absolutely can't say why.
HPDRAWORDER = 1 seems to work with a new hatch.. but i can't redraw everything.
Let's say i put an entire floor plan into block then draw over it. (I don't want to start a Xref discussion please) i can't send the entire bloc to the back.I used to do that with 2012, 2008, 2007.. but it's 2013 it's not working, is there a way to correct that?

So I am trying to use "fill hole" for this empty space on my mesh but it isn't working. I know I can figure out another solution to this problem but I want to know why it won't work.
First of all, when I double click the edge around the hole it doesn't just select the hole, it selects a huge ring that goes around the whole head for some reason (I'm attaching a picture).
Then when I select the edges around the hole one by one and select "fill hole" nothing happens and I get a message at the bottom of the screen that says "polycloseborder2" (I am also including a pic of this).
