There is a limit, and that limitation is not necessarily AutoCAD's fault. To see a graphical example of this, select a large range in the spreadsheet, then look at the clipboard viewer.
You will find the clipboard viewer in the accessories or system tools section of the Windows start menu. It will be in the System Tools section of the Windows Setup tab. When you look at the clipboard viewer, you should see that the Windows clipboard has limited the data when presented in certain 'flavors'. Use this procedure to 'shake off' the OLE. In Excel, copy your graph to the clipboard. When building the block definition, the selection order is the key. If you simply window off the geometry there is a good possibility the prompt order will not be as desired.
When selecting objects for a block definition, first individually pick the attribute definitions individually in the order you want to be prompted, then select the rest of the geometry. Importing Block Definitions If you want to bring in only the definition of a block such as a symbol on disk , you can use this little known trick. After issuing the insert command and selecting the file, press the ESC key at the first insertion point prompt.
You will have the definition in the current drawing for latter use. Select the block from the list at top. Click in the lower 'Description' section and enter the description. Choose OK to redefine the block with the new description. Draw the desired point identifying geometry, such as a circle at 0,0 with a radius of 0. Turn on the Preset toggle in the upper left, this makes for faster inserts as AutoCAD won't prompt for the attribute values which is automatic anyway.
To the right of the Value field, click the 'Insert Field' button. In the Field Names list on the left, click 'BlockPlaceholder', this is a special area only available during block building. In the middle column, choose the 'Position' property.
In the right column, format your output as desired. While you can lock the precision to a fixed number of places, it's not easy to modify a field based attribute later. Choose OK after completing the field formatting. Change 'Text Options' as desired. For this example we are only changing the height to 1. Most likely you will want to turn off the 'Lock Position' toggle so you can move the attribute after the insert. Choose OK to complete the first attribute. When prompted for the insertion point, pick a location or enter coordinates such as 1.
Choose Yes to save the changes. As you insert them into the drawing the coordinates are filled in automatically. Changing the Insert Units to 'Unitless' is recommended. It's likely you will want to turn on the "Align below previous attribute definition" toggle. Then close the Block Editor and Save Changes.
The most important consideration now is that existing inserts don't have a placeholder for your new attribute! All the instances of your insert now display the newly added attribute with the default value. You can now simply double-click an insert to change the value in the enhanced attribute editor.
Block Base When designing blocks, it's always best to create the geometry centered around the origin of 0,0. Sometimes users can create a block from geometry in model space and it ends up difficult to use when inserting the block. To correct this, issue the BEDIT command, select the misbehaving block, then use the move command to move the block elements to 0,0. You may need to use a specific base point such as the midpoint of a feature to 0,0.
That way it will take on the properties of the layer it's inserted onto, or the specific properties you specify in the properties dialog. Failure to do this can mean confusion. In this case the invisible insertion point prevents the layer purging.
When preparing a drawing and its geometry to become 'insertable' into another drawing, you must consider its coordinates and then optionally the BASE variable. The preferred method for blocks is to move the geometry from the desired 'anchor' to coordinates of 0,0,0. If you don't want to do that, you should issue the BASE command and pick a point at the anchor.
Another problem scenario to watch out for is when the geometry has been moved to 0,0 and the current drawing had a base other than 0,0. In this case simply issue the BASE command and type in 0,0,0. Some offset distances are greater than specified? This can expecially occur when offsetting polylines. As the interior angle decreases, the distance between offset endpoints increases.
However in parallel sections the perpendicular distance 'should' always be For example with a unit offset. Why won't AutoCAD create my large array? AutoCAD sets a default limit of , segments. However you can change the default value to any number from to 10,, To increase the value, enter the following at the command prompt.
The example shows increasing the value to 50, Note that the name MaxArray is case sensitive and must be entered as shown. There are several ways to do this: The following example indicates the next point is 12 units to the right positive X and 6 units down negative Y. You specify the distance and angle to the next point. The following example indicates the next point 15 units away at a 45 degree angle.
Much like relative polar except you have the ability to designate the amount of rise or drop at the new point. The following example indicates the next point 15 units away at a 45 degree angle, but also is 6 units lower. Much like relative cylindrical except the rise or drop is determined by an angle. The following example indicates the next point 15 horizontal units away at a 45 degree angle in plan view, but also lifts 12 degrees in the XY plane. While it lacks in interface appeal it more than makes up for it in capability.
Take the ability to snap to a point between to endpoints. Consider this example where a circle is placed halfway between the endpoints of two lines. The key is when prompted for any point, enter 'CAL and type in the expression. In the case of MEE it knows you want endpoints and you don't have to use an object snap when picking. Also bear in mind that MEE is only one of dozens of expressions available at the prompt.
Even though you have set to Surveyors Units it won't work right unless set this way. You put the sign first, which means relative to the last point. Next comes the distance. Last is the bearing. Without the multiple prefix you would need to reissue the command before each pick location, now you can repeatedly pick the points until done.
Press ESC to cancel the repeating command. Using BPoly to Shrinkwrap Users often need to generate a boundary polyline around multiple polygons or a collection of 3dfaces forming a surface definition. Simply surround your geometry with a rectangular polyline. Create a new layer and set it current.
You may occasionally receive a drawing from an outside source that causes this problem. When you pick objects at the command prompt, they highlight and grips appear.
But on some systems this stops working. The Object properties toolbar will start working again. Number of Command Lines When you press F2 and look back at the command history, you may notice that at some point it stops. The default number of lines is set to On R14 you could change it in the preferences dialog.
Unfortunately and higher has regressed. You have to use a to lisp expression setting like MaxHatch. To check the current number of lines set: You can use these commands to control it. If you do you might want to keep it in the lower left corner. Simply enter that at the command prompt and enter a new value of 0.
