AutoCad :: Extruding / Pushpull Large Array Of Circles
May 29, 2012
I need to design a 'stencil' of sorts - but it just needs to be an array of circles separated by a constant distance. its an array of 200 micron diameter circles separated by a distance of 500 microns each (between centers).
Its super easy to make this array, but when I try to 'pull' it into the third dimension, or extrude the array, I get an 'invalid' error. Or the highlighted objects just get 'unhighlighted' (for the lack of a better word) once i hit enter after selecting them all.
Also, I made the entire array into a 'block' of easiness.

Okay, I'm new to associative arrays, I'm attaching a drawing so you can see what I'm trying to accomplish with this. I'm doing an elevation view of a slab that has a cross section of the rebar. I've shown one of the bars spanning from left to right, represented by a rectangle, and the cross section of the bars running front to back represented by circles. You can see what I'm trying to show here. In the drawing I've attached, the top three sketches are examples of how this would look if it were working correctly.
What I'm trying to do is create an array (of circles) that will stretch to the length of the bar spanning left to right. I want the quantity of items in the array to automatically change based on the length of the bar and the spacing of items, so if there is 6" of spacing between the items instead of 12" it will automatically add twice the amount of items to fill in that space. I've been trying to use a path array, and it isn't working the way I want. I'm not familiar with rectangular arrays, so not sure what to do there either.

I'm trying to create an array from one block with the option to specify columns, rows, respective offsets as well as angle. The original block comes from a 98kb dmg and is pre-inserted at a specific x,y,z in the model space. The issue I run into is whenever i try to create an array with say more than 200 lines and 200 columns, the machine locks up. It generally will create the array however it can take upwards of 5 minutes.
// Our list of Attributes BlockReference blockRef = bref; AttributeDefinition attDef1 = new AttributeDefinition(new Point3d(0d, 0d, 0d), type, "Type", "", db.Textstyle);attDef1.Invisible = true; AttributeDefinition attDef2 = new AttributeDefinition(new Point3d(0d, 0d, 0d), device, "Device", "", db.Textstyle); attDef2.Invisible = true; AttributeDefinition attDef3 = new AttributeDefinition(new.
[code].....

I have sometimes an array with 10x45=450 assemblies. Because this slows down my computer dramaticly I use LOD to suppress parts within the assembly. The problem is that I have to expand every single assembly in the array, select all of them and than choose the LOD I want. This takes me a lot of time. Is there a way I can select all assemblies within an array with one (or two) clicks?

I'm trying to use the PATH array feature on 2013 to array stairs, and I can't get the array to be 100% accurate. It seems like CAD rounds the decimal to the nearest 3/4" which could be causing the problem.
I set my run to 10.5" and rise to 7.25", array along the angle of the stringer, and there's always a small overlap on the stairs. The "distance between" should be 1'-209/256" and CAD rounds it to 1'-3/4" which is where I believe the error is. Is there any way to fix this or array this correctly? Otherwise...back to the COPY method I suppose.

I'm trying to make a logo. Circular logo with an inner ring maybe 4 px wide and 15 px inside the rim of the outer circle.
Basically I want a blue circle with a yellow inside ring. What's the best way of doing this? The only thing i can think of is: creating a blue circle marquee, and then another (trying to estimate a new circle size and change the color) that is yellow, and then making another smaller blue circle inside the new one. That's just ugly.
I tried the edit/stroke but that just gave me a stroke around the outer circle; it didn't put a ring inside the circle 15 px down.
Also I tried to contract the original circle by selecting it, then Modify/contract. That's got me a selected ring, inside the circle. Now how in the world do I make that little ring yellow? It just remains selected and I can't seem to find a way to color it.

I'm doing a small 3D assignment for class, and I need extruding these trusses in my drawing 2". I'm aware that they need to be a solid polyline object in order to do so, however I can't seem to figure it out!
Here is the file:

I have the need to curve a region, then extrude it, is this possible?
The region is a flat view of a plasma cut plate with lots of holes/shapes that then gets rolled, doing it the way I describe would exactly re-produce in cad how the finished physical product comes out.

I am starting up my class again using AutoCAD Civil 2011. I want to extrude a circle or just a closed pline to a solid. I have done this many times before, but now it is not extruding to a solid, just a "Surface Extrusion". My commands are C:circle; C:region; (shows as filled circle and confirms it is a region); and finally C: extrude ; when I extrude it it is not a solid but rather a hollow "Surface Extrusion". Is it a function of 2011 and something I have turned on?

I am having trouble extruding(cutting) a shape into a cylinder. I want to cut the cylinder with a certain shape but I want to cut it tangent to the cylinder instead of just straight down through it like a front view.

I'm setting up so isometric views with legacy hidden settings so it properly displays as it would in real life. I started out by making 2 rectangles (one 1/4" bigger than the other) and centered them together.
I then turned it into one polyline so I could extrude it.
But now it thinks that it's one big chunk of metal in the center, and not hollow. I don't know how to get a hollow piece of something.
make a hollow object that had a wall width??

When I try to extrude this closed polyline (yes it is closed) I get the message "Cannot sweep or extrude a self-intersecting curve." I do this sort of extrusion all the time (closed polylines with various geometry) and usually have no trouble.

I am in the process of drawing this bookshelf:
Bookshelf.jpg
As already visible on this picture I am having trouble with extruding some of the shapes of the shelves.
The tricky thing is what I have been doing differently with the one shapes where the extruding leads to the desired result and the others where it does not work. I have been trying different things: changed the shapes from splines to polylines etc. Does not work...
I´ll add a reduced version of the drawing here: the original shapes are on layer 0, the extrusions on 0 - X

Is it possible to extrude a curved 2D surface to give it thickness? For example, if you were to draw a loop the loop shape but it was just flat, could you extrude it out to give it thickness?

I am currently working on a complex roof truss (kind of similar to the new roof in Kings Cross station) and have currently got it in autocad as thousands of lines.... I am hoping to 3d print it and require all the lines to be solid cylinders of which I can convert easily enough individually... Any way of converting them all to cylinders to save having to do this over 5000 times!!

I have tried, such as creating lines in a 3D sketch and projecting the geometry to surface, and creating a work plane, and both don't seem to work for me.... I'm trying to cut out a 5.8mmx14mm rectangle out of a cylinder. When I project the geometry to the cylinder's inner surface, I cannot trim the solid in order to extrude. I've attached the file.

I can't post the original files, but I have gotten permission to post jpegs of what I am trying to do.
My end goal is to fill in between the grey part and the surface. The surface comes from another part in the assembly, and I used Copy Object to get the surface in this part file. Ideally I would like to do something like Extrude> To Next and select the surface as my terminator. I have done this with success with curved surfaces, but not complex curved surfaces. Does Inventor not handle extruding to complex curves?
Another option I tried was simply extending this part out beyond the surface using the Split feature to trim the part. Again, to no avail. I also tried creating a subassembly of this part and the part the surface is derived from with this part extending beyond the surface, deriving it and subtracting the surface part so I could use Delete Face with the Lump option. No dice there, either.
There was a hole in the side of the surface where I am trying to extrude the part (it is still open on the other side of the surface), but I used Patch and it seemed to fill it in just fine.
How to get accurate fill volume data in complex assemblies.

I have been extruding bodies around parts, then using their verticies for the frame generator (to guard around complex machinery.I then suppress the body and am left with the guard frame.
when i go to get the mass for the part, it includes the volume of the solid body which was used to give the outline.how can i turn the material property to zero density?

I have a arc that is about 21.5 radius and .5 in width. My problem is that it is going on a bench that i have made and the corner piece needs to be cut out and i am trying to figure how to make this line look like an actual piece. I can extrude the piece to 21 inches tall, but then i need it tapered back to fit this bench were making.

The problem I'm having is presspull/extrude irregular shapes.
I have some really weird, irregular shapes that's consisted of fillets, lines, and arcs. For some reason I cannot REGION it. But I can HATCH it, and give it a solid inner part.
My irregular after being filled, can't be extruded. When I try extruding it, the command line goes "This kind of shape cannot be extruded", without any explanation, or keywords.
Then, if I try to PressPull, it only PressPull the outline of the irregular shape, without pulling out the inner bulk part.
Then if I try to do anything more, my AutoCad likes to go "About to regen -- proceed?" error.

I've created an object containing several shapes in Illustrator CS6 and exported it as a DWG, In Autocad 2014 I've exploded the block using XPlode command, now I want to extrude this shapes so I can create a geometry and start doing booleans and so one.
When I click in the Extrude option and select any of this shapes I get an error saying that objects of this type can not be extruded. I'm completely stuck I've been going back and forth from illustrator to Autocad 2014 and I can't find what's wrong.
P.S. The shapes in Illustrator have no stroke or filling so you will have to "Select All" to see the whole thing. The DWG and AI files are inside the attached zip. The DWG has been exported using "File > Export" w/ "Maximum edit-ability" from Illustrator.

i need to create a solid by extruding/offseting a spline surface (attached picture). The problem is, a solid created by simply extruding this surface "outside" would cross itself, so autocad does not allow me to do it (neither extruding, surface offsetting is working) I tried to make a cube then using this surface as a splitting spline - however a solid created this way is flat on z-axis. How can I do this ? Everything is fine with the spline as well as a surface - it's closed one. Obviously the problem is in the fact in the self intersection of the extruded solid. So maybe using it to split a solid is a better approach?
