How to Draw on New Plane Autocad

Cartoon planes are used to add geometry to the model. Instead of the freedom of calculation the geometry in 3D infinite, the geometry is always snapped into the plane. In addition to the obvious advantage of existence able to describe flat geometry, regions created with construction objects fatigued in a plane can be meshed with the 2D mesher. See the folio Meshing Overview: Meshing Hand-built Models: 2D Mesh Generation for details.

When using a drawing plane, the FEA Editor environment is in sketch mode. Hence, the terminology sketch and cartoon airplane volition be used interchangeably.

Create a aeroplane

Additional planes can be created by using Describe Draw New Sketch Aeroplane, or by right-clicking on the Planes branch of the tree view and choosing New Aeroplane.

You lot can select between the three planes parallel to the global axes (XY, YZ or XZ). Y'all can also select the Avant-garde option or the 3 points option to define an off-axis plane. Activating the Use Offset check box will permit you to get-go one of the global planes from the origin. A positive start places the plane in the positive management. For instance to draw in the X=10 aeroplane, select the YZ pick, activate the Use Offset check box and type 10 in the side by side field.

Enter, utilize, and get out Sketch Way

To enter sketch mode to draw on a plane, right-click the desired drawing plane in the tree view and choose Sketch. When in sketch mode, a grid will appear in the brandish expanse and the cartoon airplane is shown in assuming in the tree view. All sketching will be done in this plane. The grid can exist turned off by right-clicking on the plane in the tree view and immigration Visibility. The spacing of the grid tin can be customized on the Options Sketching tab.

Geometry is added to the sketch just like any other geometry: use the commands on Describe and Design console of the Draw tab. All properties such every bit function, surface, and layer number, and whatsoever object-specific input, are used in the sketch mode just like it is in the 3D mode. (See the page Calculation Geometry for details.) The just real deviation between adding these objects in 3D style versus adding them in sketch mode is whether the entered points snap to the drawing plane or not.

When drawing sketch entities, if the cursor is close to a grid point, a lock icon will appear on the cursor. If you click, the detail you are drawing will be snapped to that grid point. Besides, you can snap the new geometry to existing geometry. The points will be projected into the drawing plane.

When an item is added to a sketch, a branch is created nether the appropriate part that lists the cartoon airplane, and this branch includes an entry for each item fatigued in that sketch. Click the drawing plane entry under the part to highlight the corresponding items.

To exit sketch mode, correct-click the drawing airplane and deactivate Sketch. Too, activating the sketch style for some other plane will deactivate the sketch manner for the current aeroplane.

Re-create betwixt sketches

Here are the ways to copy items or sketches to other sketches:

• Change Aeroplane. All construction objects assigned to a sketch (the Airplane entry in the tree view listed under the part) tin can be moved or copied to a different plane. Correct-click the sketch entry and cull Change Plane. The Transfer to Unlike Aeroplane dialog will appear and list the available planes in the Target Plane drop-down. (If necessary, create the new target plane beforehand using Describe Draw New Sketch Plane.) If the Copy to target plane option is non activated, the selected sketch volition be moved to the target aeroplane. When the two planes are parallel, the move or copy operation is directly frontward. When the 2 planes are not parallel, then the transformation may be harder to visualize (but is still straight forward). The 3D coordinates of each object are converted or projected to local (U,5) coordinates within the existing sketch. The objects are placed in the target plane with the aforementioned (U,Five) coordinates, then converted to 3D coordinates. So, if a structure line is from (0, 3, 4) to (0, six, 8) and sketched in the global YZ plane, it would parameterize as a line from (3,iv) to (vi,eight) in (U,V) infinite. These same (U,V) coordinates in the global XY plane would transform to a line from (iii, iv, 0) to (six, 8, 0) in 3D space. Note that the part, surface, and layer number of the construction objects are non changed, so the branch for the new sketch appears in the same part as the original sketch.
• Copy and Paste. Individual construction objects in one sketch of a part can exist copied (or cut) and pasted into the same sketch plane in another part. Select the objects (either in the tree view or in the display area), right-click and choose Copy or Cut. Then select the target sketch airplane in the tree view, right-click, and choose Paste. Also, you tin can elevate the entries from the sketch in one role to the same sketch airplane in some other role and drib them into the sketch. Naturally, this functioning requires that the target sketch exists in the target part. Other than changing the part number of the copied object, the surface and layer number remains the same.

Note: If a construction object in a sketch is selected and inverse with the Depict Blueprint Motility or Re-create command, then the object is no longer associated with a sketch. It becomes a 3D Object and is listed in a separate branch under the function.

Convert from 3D objects to a sketch

There are situations in which a construction object is non in a cartoon plane, so the tree view lists the item as a 3D object. Some commands are not available on 3D structure objects, such as 2nd meshing. These 3D objects tin can exist copied to a sketch as follows:

1. Select the 3D structure objects with the Selection Select Structure Objects command.
2. Copy or cutting the objects to the clipboard. Right-click and cull either Cut or Re-create.
3. Actuate the drawing aeroplane into which the objects should become. (Right-click the appropriate plane nether the Planes co-operative of the tree view and choose Sketch.)
4. Paste the 3D objects into the function. Right-click the part name in the tree view and choose Paste. Note that the object must exist pasted into a sketch on a different part than the original objects.

Annotation that the original 3D construction object is not projected into the drawing plane. Therefore, the object should prevarication in the plane into which it is beingness pasted.

Calculate the properties of a sketched region

The cross sectional backdrop of a sketch tin can be calculated. The guidelines for the sketch or sketches are as follows:

• Depict the region to be calculated using structure objects.
• Depict the objects while in sketch manner.
• The objects tin be in different parts but demand to be in the same drawing plane. The combination of all parts on all selected sketches will ascertain the region or regions.
• Any drawing plane tin be used. The results will exist in the local coordinates of the aeroplane.
• The sketch must enclose an area or multiple areas.
• Holes inside the area are permitted.
• Regions tin overlap, in which example the overlap region is calculated as if information technology were a hole, but dissever regions should non touch. See the post-obit effigy.

(a) Two overlapping regions (to a higher place) are supported by the 2D Moment of Inertia calculator. The overlapping region between the foursquare and the circumvolve is interpreted as a hole in the cantankerous section. The calculations are based on shaded the regions (below).

(b) 2 regions that do not overlap (higher up) are not supported by the 2D Moment of Inertia estimator. When the control is executed, the problem areas are identified with the inverted triangles (below) . To summate this area, remove the line in common between the square and the semi-circle, creating a single, contiguous region. (Alternatively, duplicate lines could be used where the regions meet—one for the foursquare and one for the semi-circle. For example, duplicate lines are required if the square and semi-circle belong to split parts, and the two regions will be meshed with the second mesh engine.)

Once the sketches are made, either select the airplane in the Planes co-operative of the tree view or select the airplane entries in the tree view under the part, then correct-click, and choose 2D Moment of Inertia. Selecting the Planes branch is equivalent to selecting each of the individual planes appearing under each part. The calculator will carve up the combined sketches into a series of horizontal rectangular strips and perform a numerical integration based on these strips. The results are given in the 2d Moment of Inertia Results dialog and consist of the following:

• Area
• Heart of Gravity location, given in local coordinate system of the plane (u,v). The global coordinates of the center of gravity can exist determined by inquiring on the construction vertex that is added to the model.
• Surface area moment of inertia about the horizontal and vertical axes of the plane (u and v axes) passing through the middle of gravity of the sketch. The orientation of these axes is given every bit a vector in global coordinates in the Local Orientation

A construction vertex is also added to the model at the location of the center of gravity.

Tip: The accuracy of the calculation depends on the number of divisions used to split the sketch into rectangular strips. The meridian of the sketch (in the 5 direction) is divided into the number of divisions specified under the Options Sketching tab.

The Save Results dialog volition appear when the Save button is clicked. Choose the file proper name and location of the area adding results. Actuate the Append cheque box on the Salve Results dialog earlier clicking the Salvage button to append the electric current results to an existing file. Otherwise, the existing file volition be overwritten with the electric current results.

Like calculations can be performed on fully meshed models by using the Assay Analysis Weight and Center-of-Gravity command. See the page General Options: Weight and Center of Gravity Estimator.
