Define

Define Section

Define Section Tekla1.png
  • In the Define section of the Tekla Import screen, users will be able to use the following basic functions in order to define their part in preparation for use in the Bend-Tech software. After each part is fully defined, it can then be saved to the Parts tab before it can be transferred to one of our other designers.





Create Tube By Dragging:

Click the Create Tube By Dragging Create Tube By Dragging Tekla1.png button, then click and drag your cursor of your mouse over any straight section of tubing that you'd like to define. IMPORTANT: This works best if you refrain from including bends, zoom in close to your intended tube, and drag the line in a direction that runs opposite of the length of tubing you are trying to define. See the illustration below for more detail.

CAD Brightness:

Adjusting the CAD Brightness CAD Brightness Tekla1.png will either brighten or dim the color of all geometric features within the imported design. This can be used to see defined parts when dimmed and see raw geometric features when brightened.

Cutting

Cutting picture Tekla1.png

The Cutting tab contains the tools necessary for adding cuts to the ends of parts. Wrappers can be printed which, when wrapped around the end of a tube, mark where the tube needs to be cut.














Make Cuts

Click the New Cut New cut.png button and click a part. The cut part will be highlighted in green once selected. Click a second part, plane, or multiple parts that the first part will be cut to fit against. The second and any consecutive selected parts will be highlighted in red. Click the Complete Complete.png button. The cut should appear in the list of cuts in the Cutting tab and shown on the assembly.


Cutting Tekla1.png


Click the "Auto-Cut" Auto cut.png button to let the software attempt to generate all cuts in the assembly project.


Click the "Auto-Miter" Auotmiter1.png button to extend the lengths of intersecting tubes past their center line so they can be cut equally.

Cutting Plane

Using the "Cutting Plane" function to cut a section of tube is different from cutting tubes that intersect. This tool is used for cutting a specific place on a bend or straight tube that does not intersect another tube.

Using the cutting plane feature, a custom plane can be defined and used to place cuts anywhere on the assembly design.

To place a cutting plane, click the "New" New plane.png button under the "Cutting" tab and click on a PickPoint to define the center/base point of the plane. Then click the first and second direction of the plane.

Once a plane is place in the assembly, it can be used as a cutting feature and will allow straight cuts to be placed anywhere.

Cutting plane.png

To move the plane, click the "Move" New plane move.png button. Then click and drag the move tools directly on the plane to move, resize, and rotate the plane. See image below.

Plane move.png

Once the cutting plane in in the correct position, the user can record a cut by selecting the "New Cut" New cut.png button.

Then, select the tube that you are trying to cut, followed by the cutting plane itself. If you've done everything right, the cutting plane will be highlighted when you place your cursor over it.

Lastly, select the "Complete" Complete.png button and the new cut and information will show up on the left of the screen in the Cut Chart section.


Cut Settings

If the Outside Diameter Only option is checked, the software will not display the inside diameter cut line for each cut. Using a hole saw requires the checking of the outside of the material only. "Check" the option "Outside Diameter Only".

HoleSaw3.jpg

Using a grinder or plasma cutter requires checking of both sides of the material. "UnCheck" the option "Outside Diameter Only".

HoleSaw4.jpg


If Distance to Perp of Bend is checked, The red line will indicate the distance to the perpendicular of the bend. The cut wrapper's red line will display the distance to the tangent of the nearest bend combined with the outside radius of the bend.

If the Hide Completed Features option is checked, completed features from the cut will be hidden in the design.

If the Ignore Tube Ends option is checked, all cuts will ignore the excess tubing leftover from all other cuts.

If Mitered Cut is checked, all cuts will be calculated as straight mitered cuts. If you are using a hole saw to cut your tubes leave Mitered Cut unchecked.


Cut Chart

A chart displaying a list of all the cuts currently applied to the assembly will be shown as well.

Click on a cut to see a preview of the cut on the 3D model of the assembly.


Click Delete Delete cut.png to remove the cut from the tube, or click Delete All Delete all cuts.png to remove all cuts from the Assembly project.


Click Print Print cut.png to print the currently selected wrapper, or click Print All Print all cuts.png to print out all wrappers for the entire Assembly project.


Cut wrapper.png

Click the Details button Details.png to see a preview of the cutting wrapper. On each wrapper, there is a red line with a number on it. This line is used for lining up a wrapper on a tube. The number is the distance from the end of the tube that the red line should be.


Click the Select button Select cut.png and click on a cut in the display area to select it from the assembly directly.

Cutting Definitions

  • Setback - Distance from the end of the tube to the centerline of the cross tube. This point is the intersection of the cross tube (centerline) and the centerline of the cut tube.
  • Offset - The up/down distance from the centerline of the cut tube to the centerline of the cross tube when looking at the face of the cut.
  • Angle - The plunge angle of the holesaw. A zero degree angle would be a plunge at a perpendicular (90 degree) angle to the cut tube.
  • Rotation - The rotation of the holesaw plunge in relation to the closest bend (or opposite side of the tube in the case of a straight tube).

Holes

Holes Tab Tekla1.png
  • The Holes tab is used to create hole geometry on your defined parts in order to transfer the data to the Dragon designer. These holes can then be assigned an action of cutting, engraving or marking based on your needs.















Hole From Lines:

Click on the Hole From Lines Holes From Lines Tekla1.png button followed by the defined part you'd like to place the hole on, then select a geometric feature that represents the first line of the hole followed finally by a line on the opposite side of the intended hole cutout.
