AutoCad 3D :: Constrain In Positive Z Plane Only?
Nov 29, 2013
I've not seen it mentioned anywhere so I must ask. When in 3D modelling, is it possible to set AutoCAD to constrain drawing and movement in only the positive Z axis? I'd like to draw obviously in the XY plane but also only in positive Z (above ground?). I don't think i'll ever need to draw anything in the negative Z plane, which by my understanding would be actually underground (correct??). If it is at all possible to constrain in the positive Z plane, would there be a way to temporarily over ride this for the times I may need to Press Pull a hole out of a solid?
I have this strange knack of drawing in Top view in a left viewport (model space) then extruding in the right SW viewport then sometimes when I try ti move objects the end up underground (negative Z plane).

I'm a playground designer and we're currently in the process of updating our systems to Inventor. Over the next few years I'm going to be working on many different assemblies all using the same parts and sub assemblies, many of which need to share the same ground plane.
I'm wondering if there is any easy/quick way to make certain parts (not all) automatically constrain/flush to the ground/XZ plane when I place them?

If you edit a section view sketch you can project model edges in the sketch and use them to constrain the section view line. However I cannot seem to project an included workplane to the sketch. For a particular application I really need to use a workplane because the model is actually a dummy that gets replaced by a vb macro. So any projected model edges will loose their reference.
I found out that I could use a sketch in the model to create the section view. In a model sketch it is possible to project work planes, so this looks like a good solution. However I do prefer the flexibility that you have when you use a drawing sketch.
How to use a work plane to constrain a section view, other then the model sketch method explained above.

I am having a problem when attempting to measure the volume of a solid in Autocad Civil 3d 2013. It returns an error: "One or more diagonal terms are not positive." I have run a check from solidedit and it returns as a valid solid.

I have a macro to create DXF files for all sheet metal parts in an assembly. What I now want to add is 2 functions :-
Move the DXF output to be in the 1st (positive) quadrant so that the left most entity is touches with the Y axis and the bottom most entity touches with the X axis,Add iProperties like Part Number, Material, Thickness and Qty as text to the DXF file.
Any takers?

I have in the past needed to create filters that had both a positive AND a negative in the parameters.
One of my most common examples: Layers in a specific XRef with names that do not contain specific string.
I tried XRefName|*[~anno]* and it gave me ALL the layers from the XRef (including the ones with anno in the name).
I also tried XRefName|*~anno* and it didn't list ANY layers.
It it possible to do this? I've read throught the docs on using wildcards in the filter properties but don't see anything.

I want to create a positive form of the inside of a differential housing.
My idea was to put two planes on the edges of the housing. Then using the Sculpt Tool to create a New Solid of the inside of the housing.
With the Derive Tool i could seperate the two Solid Forms from each other.BUT... When I want to create a New Solid with the Sculpt Tool I get the error ' Create Sculpt feature failed'.
I've tried to Derive the part to a Sureface model, but that didn't work.

I'm want to reproduce a differential housing. Therefor I need a part which is identical to the inside of the housing. In other words, I need a positive part inside of the housing.
I've tried to do this with Derived parts by placing the differential housing in a large block. But then I get a block where lining of the housing is missing. So i can't do anything with this derived part.
I have attempt to upload the file, but it is too large. Even when i try to compress it.

I am photographing 2 1/4 negatives with a CANON 50D and macro lens. Then in Photoshop CS3 I was looking for the filter to convert the negative film file into a positive file so I can work on it with Adobe and then print in on my Canon printer.. I have tried to sample the orange base color and take that out and then invert and then increased the contrast curve.

I want to produce three positive transparency (C M Y) "films" that I can lay on top of each other over a white light for demonstration purposes (to simulate the behaviour of a slide film). Obviously each film has to be printed in its own colour (Y, M, C).

I have created a column graph with a large amount of data. I would like to apply two different colors to the positive and negative columns. Whenever I click on a column and go to object>graph> the column section is unavailable. I checked to see if the graph had become ungrouped, even though I never selected it. If I select the graph as a whole it does not say ungrouped. When I select a column the ungroup tab is greyed out. Does that mean my columns are ungrouped?

I need a plugin that can invert positive and negative space with transparency.
Example: I have a filled square in the middle of a transparent image. I use the plugin, and the square is now transparent, where as the originally transparent space is now filled.
Visual example:
Of course, I need this to do more complex shapes. Also notice the blur is accounted for.

I have a block that I'd like to be able to keep within the dimensions 4'x8'. The block is in the attached file as Sheet Stock
All 4 points need to be able to be moved independently, but the overall shape needs to be able to fit within 4x8.

I wish to limit the user input of and edittext to only allow a positive number, float or int. I do not yet know my Regex good enough to do this. I realize that I must get better at regex but in the meantime how to do this ?
I have used this so far on the edittext:
function checkTextInput()
{
if (this.text.match(/[^0-9.]/g))
{
this.text = this.text.replace(/[^0-9.]/g, "");
}
}
Which matches
000.0001
0.45.000.1
...1
which is not desired.
Desired is
0.n
.n
n.n

I want to image trace this photo to create logo. However the way the logo will be applied means that there can be no negative space less than .35mm or 1pt or the heat transfer will have them blend together.
How can I image trace while maintain all spaces (both positive and negative) are atleast 1pt sq?

I've managed to hack together some code to draw a rectangle and dimension it. Now I want to constrain it to the origin. I figure either using two dimensions from a top/side to the origin and setting the dimension as half of the other respective dimension would work. Or constraining the center point of a top/side line to be vertical/horizontal to the origin.
The problem I'm having is I do not know how to reference the origin. So until I figure out how to reference the origin point I can't use either method.
Public Sub DrawSketchLine() ' Check to make sure a sketch is open. If Not TypeOf ThisApplication.ActiveEditObject Is PlanarSketch Then MsgBox "A sketch must be active." Exit Sub End If ' Set a reference to the active sketch. Dim oSketch As PlanarSketch Set oSketch = ThisApplication.ActiveEditObject ' Set a reference to the transient geometry collection. Dim oTransGeom As TransientGeometry Set oTransGeom = ThisApplication.TransientGeometry Dim oUOM As UnitsOfMeasure Set oUOM =

With reference to dynamic blocks. When I insert the block it is no problem, but how do you constrain the block, so when you re-size it using the block table the center of the block stays on the insertion point and is symmetrically around that point!

I am trying to CAD a model rocket I just made so I can test the aerodynamics of it. I have all of the individual parts made in inventor, but I am having trouble getting the fins on the rocket.
How can I constrain the fins (which have a flat face) to the outside of the cylindrical rocket tube? The photo shows the fin and the face (the narrow and long face) that I am trying to constrain to the tube.

SO what is everyone say, trick about speeding up constrain execution. I have started working on this new project with 2013. And i'm finding myself losing alot of time. Basicly what i do is insert part from our database or content center and assemble them. So 80% of my activities on inventor are constraints. Right now i have this assemblies 175 / 156(small to me). And executing a constraint is minimum 4 seconds each time. If you consider that about 3 contraint is needed for each piece and final total part will probably be around 1000. i'm losing alot of time here
Yeah, i am not using preview. Why is inventor recalculating that much each time? Is it doing a rebuilt after each constraint?
What have you done that really increase the excution time of constraints?
