AutoCad 3D :: After 3D Extrude Loose Original Polyline?
Feb 6, 2013
I draw a closed polyline and then I extrude it. But when I want to see the 2d plane and hide the 3d version I cannot go back as the polylines are extruded and everything is disappearing. Should I draw a second poly over the first, then create a new layer, name it for example 3dpolywalls ? Is this the most common technique? Or there is a more efficient way ?
I've had a problem for a while now trying to extrude a 3d polyline into a 3d solid. The polyline is on different planes which is one cause of why it won't work. Instead of extruding into a solid it only does the sides making it a mesh rather than a solid. If its on one plane I know it will work.
I'm trying to model a 3d leadscrew. How can I extrude a 2d closed polyline in a straight line while at the same time twisting it (360° twist for every 1.5" along the path). I've tried loft, sweep, extrude all using the helix as a path. When I can get a result, it ends up being a corkscrew.
I am not able to extrude closed polyline shapes. I get the following message:
Cannot create solid from open curve.
Cannot sweep or extrude non-planar objects.
Unable to extrude the selected object.
Other folks have opened my drawing – some can extrude, some get the same or similar message. I’ve tried re-building the shapes to extrude. It worked with one thing this morning and now it won’t extrude again.
I am designing a logo using the Extrude and Bevel effect for some depth. When applied--using the Plastic Shading option--it darkens the original colors.Is there a way around this to maintain the hue in the original color.
I have a scanned drawing (PDF) and I want to use it a a xref so i can redraw it (originals have gotten lost ). But is really big and makes autocad really slow.
Is there a way to make a scanned drawing in PDF have loose object / lines again?
So we have this custom construction note routine. It creates all the notes with station, offset, blah blah , and it is all together as once piece. So if you move the note group the leader will stay attached to it and it holds all of the label properties.
When I copy clip, wblock, insert these key notes into another drawing they are no longer a group and there is no way to move them all together.
This has created a lot of extra work and moving stuff around that does not seem necessary.How can I copy or move construction key notes from one drawing to another without losing the group properties. I have tried WBlock and making sure the grouping is on when I copy and paste/insert them but it still doesn't work.
Oh and we are running a 64bit 2013 with the carlson suite application,
I've never cared for the Ribbon. IMO it takes up a lot of valuable screen real estate and spreads out commands I find to useful to be grouped together across multiple menus. I did like how the Menu Bar was laid out in LDD because all the commands for anything I could do with alignments, for example, were all in one place.
Here's how I set up C3D to have an UI more like LDD:
1. Show the Menu Bar: click on the dropdown menu button on far right of the Quick Access Toolbar (at the upper left of the C3D screen) and select Show Menu Bar. Old familiars like File, Edit, Points, Alignments, etc should be visible.
2. Get rid of the Ribbon: type RIBBONCLOSE into the command line and ta-da!
I've been working on a poster composed of several groups of layers and probably around a total of 80 layers. When I flatten the image, I loose all of my layer effects, things like bevel and emboss on text get flattened out.
When I upload photos to[URL]... They will either be a very large file size and delay the download of the page or they will come out grainy. I have tryed adjusting them in Photoshop, but I will either loose quality or they will not be compressed enough. It there an easier tool that I am missing?
I installed the download/trial version of X4. I decided to purchase but went through an education/academic seller since I work at a university and get better prices.
I thought I could just input the serial # of the disk I bought but obviously there is a difference in the 2-versions since it won't accept the "educational version" serial #.
So, I figure I need to uninstall the download/trial version and install the what I got on DVD.
I am concerned about loosing the info in the libraries. I made a spare copy of the projects, just in case the uninstall does something with them.
Is there a way, when you are drawing a polyline, to have the tooltip box show the cumulative length of the polyline, rather than the length of the current segment being drawn?
Due to modeling purposes, I need to convert a 3D polyline to a spline. What I have been doing is:
- change polyline fit/smooth to cubic from properties - convert polyline to spline by typing spline -> object - method -> fit from properties
You can see the original 3D polyline (green) and the resulting spline (magenta) in the attached drawing.When I zoom in and measure the distance between the two entities at different points along them, at some points the perpendicular distance exceeds 5 millimeters, and I want to ensure the deviation remains under 1 millimeter or even less.
I know I can change the knot parameterization of the spline, and this does work at some locations, but the difference increases at others.Why is there a 5.6 mm difference between the spline fit point and 3D polyline vertex, as measure in the attached drawing?
Now, I can go and manually stretch the fit point to coincide with the vertex. Also, I can add fit points between existing ones to drag the spline closer to the original 3D poly.
However, some of my polys are really long, and it is very time-consuming to do this manually while measuring points along the entities to make sure the distance stays small enough.
how to automate this process? For example a lisp that would maybe take the original vertex points, add say maybe 3 (not too many) new ones between them, and then generate a spline while making sure the deviation is less than the set value of 1mm? I am using AutoCAD 2013.
I've been working on a custom polyline object, and I've got it functioning!!Having said that, I plan to run its creation around picking a point for bounary selection.
(Other than trying to step through every vertecies) is there a technique I can thow the polyline data from a traceboundary result into my custom object? I've been trying to add the polyline from traceboundary to my object BEFORE it's added to the transaction by the way...I assume that's right, since I want to put it's data in my custom object then add my custom object to the transaction instead.
Is there any way at all to draw a new polyline - from the endpoint of another polyline, and have it automatically join as one polyline from the existing section??
I know this can be done via PEDIT, but its so laborious and soo many clicks, and I have alot of segmented Polylines that I need to consolidate when I draft.
When you select the option to apply any changes & overwrite your original photo does the program attempt to try to a default setting to keep the picture approximately the same size as it was before? (assuming that you haven't cropped it) If it doesn't default to a size automatically can is there an option to do so?
I can do this in AutoCAD Map but I have my doubts. I will explain in ESRI GIS terms (this is what I am familiar with) and I hope you can tell me if I can do this in AutoCAD Map. In ESRI ArcMap I can select a line and I can hit a Select by Location button. In this window I can select all of the objects that intersect my selected line. Then I can delete them or export them etc.
In AutoCAD Map I have a polyline selected. It is my road centerline. I want to be able to select all of the other polylines that intersect my selected polyline. Is there a way to do this? I need to erase those polylines. Usually I will pan to each of them and select them individually. It just seems to take a lot of time. My AutoCAD co-worker said I could use a fence and draw the fence through my polylines. It seemed to work ok but I accidently deleted extra things that I needed. So I'm back to manually selecting each one by one unless you know a different way.
I have a hat section brake shape that I want to extrude along a taper. But so far when I try to do this I don't get the results that I want. When I chose EXT, then "T" for taper and put in the angle of 9° and a length of 12, I get a very short piece which tapers in the wrong plane.
