AutoCAD Map 3D :: Surface Generation - Large Image File
Apr 20, 2011
I have created a point cloud and surface from LiDAR data. The point cloud data was relatively large from what I am familiar with (approximately 30 GB all told), and ESRI ASC surface file (approximately 8 GB) was generated after a laborious wait. However, when I attempt to add the ASC file as a raster to view the surface, MAP 3D crashes and loses connection with my PC (i.e. window freezes, and I have to force MAP 3D to shutdown). My computer is fairly updated with quad core processor, 3 GB RAM, etc. Is this not enough power to process such a large image file, or have I error ?

I have a drawing with surface profiles and the linetype generation is working on some and not the others. They're all dynamic and they're not dref'd in and like I said, a few with the same style look correct and a few are incorrect.

I am trying to edit the elevation of a JPEG image I have brought into my C3D 2010 file as an xref - I essentially want to 'drape' the image over the existing ground surface I have created to use for presentation purposes i.e. to show how our road layout is predominantly located along the ridge lines of the site.
Typically for other file types I would perform the following steps (using the classic toolbar): Grading > Edit Feature Line Elevations > Elevations from Surface > Select the existing ground surface > select object.
I don't seem to have the ability to select my jpeg xref using this approach... how else can I perform this task?

I am looking to create a collage made from 100 photos (all taken high res) to be printed large, approx 120cm x 50cm. To be able to print this size I need to keep the high resolution and hence looking for a large file output.

I am in Civil3D 2012, and am trying to render a retaining wall we doing. I set up a corridor, surface, and profile, and have it working with plans and such, but when I try my hand at rendering it looks rather odd. The surface is fine, and I can choose materials on the vertical wall subassembly, but It just shows a paper thin object ever 25' and a large surface on top. Does the top of the wall need a feature line as well.

I am trying to create a localized existing surface from a very large topo. I promoted the existing surface shortcut into my drawing, then created a cropped surface to be put in a new drawing. After creating the cropped surface the new file shows that a surface has been created, however, the surface contains no data. I am using c3d 2012.

I need to cover a rooftop with large size gravel. In the past I've used texture maps and its looked ok but I want it to look more realistic.
Substance material? Actual geometry?
If I used actual geometry, would you recommend scatter, or painting the rocks on the surface? Do either of those solutions take into account collisions with each other? (There won't be any animation...I just want to avoid rocks intersecting each other)

I have a large surface (over 1.5 million points and 20 000hectares)
I need to get a point file .csv from the TIN to be able to use it in another program.
-so i've extracted the points from my surface, but they are Autocad points.
-next step is to convert them to civil 3d points.
-I can not select them all when converting them or my computer crashes.
-so i select about 25 000 at a time, the converting takes roughly 10 minutes.
and i have over 1.5 million points to do.
how can i speed this up.
will more ram useful?

i have created a simle part file which has a User parameter (L). The part should be cut with a laser cutting machine.
My problem is, that there is 76 different dimensions for L parameter. So I have to generate 76 different dxf drawing.
is there a way to crearte a VBA code for modifying the L parameter, regenerate the part file, and export the surface of the part file as a DXF file?

I have an assembly which includes another one assembly also. So the issue is when i am generating the bill of material, the assembly which i have attached to the main assembly showing as single item with the assembly name.
The sub assembly i have attached to the main assembly by place and constaint option.does that making the problem ?

I'm woring with 2D polylines as exported from another piece of software. The problem I have is that the LTGeneration resets to disabled evertime a polyline is edited, ie broken or trimmed. Plinegen is set to 1 as the system variable, but as far as I can tell every time a line is broken etc it creates a new entity that doesn't inherit the ltgen properties of the previous line or the system variables. I know i can convert to polylines, but is there a better way?

In the sheet profile view the sampled(existing ground) profile for all 3 profiles does not generate the correct linetype(sample 1). The design drawing that I created the individual sheet from displays it correctly (sample 2). The preferences show it is generating(sample 3), it’s just not displaying correctly in the sheet itself.

I have a piece of code that needs closed polylines.
I use the following selectionfilter to filter the selection so I can only select closed polylines:
Dim sf As New SelectionFilter(New TypedValue() {New TypedValue(0, "LWPOLYLINE"), New TypedValue(70, 1)})
Today I noticed that in some drawings this filter won't select all the closed polylines for me.
After some experimenting I found the 'linetype generation' property of the polylines to be the problem. If this is enabled the above filter will not let me select a closed polyline. If I disable it, there is no problem.
How can I make my code for selecting closed polylines more robust? Is there a 'TypedValue' for closed polylines with the linetype generation enabled?

I am happy that survey figures now have the long awaited "linetype generation" on in 2013 but sometimes I need it off. Is there a toggle or am I now STUCK with it on all the time?

I have a dwg file with >9.8MB. When use Ctrl-c Autocad freeze for 15 seconds aprox.I can open and manipulate this file with other CAD Software and regenerate this file in only 531Kb (that is true for my file), with the same elements (identical file).
I try to purge, reset scalelistedit, but nothing.(I want to attach >9.8MB file but is to large for this discussion group)

Is there any work around that will force AutoCad to spool when trying to print a large .tiff image? I am trying to print an image whose file size is 150mb to a plotter.
It doesn't spool at all, it instantly prints (leaving out the image). The image is on a layer set to print etc.

I have been learning about Textures and I've been playing around with different ones and so I have come across a great site with lots of Texture files for download ...
[URL]......
Well, the files are small eg: 38x38 and 76x76 and how to create a larger image with these small images. Also, they are in .png format... if that matters.
From what I've read a Texture is a Pattern ... right? So, I have searched the FAQ's, the Manual etc. for things like: How to make a large Pattern, How to use a small file for a large Pattern and so forth but I can't find the right info.
Am I suppose to use them to create a Repeating Pattern? Can I do this and have them be seamless?

A customer has sent me a .sat file that is 297MB. Inventor is grinding at it, but its taking a very long time to open. Part count is up to 4323 open documents and the "Importing SAT Bodies-54%".
This has been running for two hours and it seems like it is getting slower and slower. My concern here is that this machine will run out of memory before it completes. It has 8GB of installed ram.
Any tips on bringing these large files into Inventor? Would a different neutral format be any faster/better?

Ive got this blank DWG with a file size of 4MB... ive ERASE > ALL on all layouts, then PURGED a few times, i cant see any layer filters. The STATUS command says it has 241007 objects. but i cant find or get rid of them.
Take a look at this DWG and let me know how i can clear it out and reduce the file size?

Uploaded to DropBox... the DWG was too big to attach to the post.

I have a file that doesn't have a lot of stuff in it, but the file size seems to be quite large in proportion. Is there a way that I can use DBList, and export the data to a spreadsheet? It would be a lot easier to search through than the F2 way.

I have successfully printed a dwg to a pdf but instead of its file size being 450k it is 1.4 m. This makes sending pdfs via email too cumbersome. It seems that even though the outcome is B&W somewhere along the line "it" thinks it is Color. I noticed that in Page Setup I no longer have the option of "DWG to PDF.pc3".

Sometimes an assembly file can become really very big.
Try to delete all components, all custom ViewReps, Positional Representations and Level of Details and save the file. If the file empty is till very big, then this post might be interesting.

In my company we work with quite large assemblies, a small project im working on now, contains 527 documents with a total of 3088 occurrenses. Our customers often request STEP files which is a real pain for us to create.
Usually we have to start exporting the assembly at closing time and let the computer work over night, and the product is often a file in the 200mb range, which is too heavy to handle via e-mail, and also takes a lot of time to import to other CAD software.
Using the Task Scheduler is not an option since our file server isnt compatible and refuses to let go of files unless they are checked out manually.

I have a large drawing with 5 meter contours that are 2D polylines on elevation. In Civil 3D 2012, when the crosshairs touch a polyline the drawing hangs for quite awhile. I've cut a piece out of the drawing so it is 28mb instead of 121mb and now the hang time is much less but it still does it. It does not happen in AutoCAD 2012.

I'm currently working on building up a library of 3D models of crane rigging for a new job. Specifically, I'm creating wire rope slings (like this 3/8" wire rope sling) but with less of an emphasis on visual detail and more on precise measurements.
In order to simplify the process a bit, I created an excel file to enter the basic four measurements of a sling (length, rope thickness, eye width, and eye length) which then calculates and displays for me the coordinates and measurements of all the objects needed to make the sling (arcs, lines, circles to sweep along those lines, etc.)
I realize now that I'm really just creating a task of endless copy/paste, and I'm looking for a better way to get through the process. How to make this work as efficiently as possible.
Is there some way that I could point AutoCAD to the Excel file and have it read all the coordinates and measurements to draw everything automatically? I also considered creating a line in Excel that would give output that I could copy and paste into a .scr, but I have never used any scripting in CAD before, so it would be new territory for me.
