Change system settings 1 2 3 4 5 6 7 8 9 10 11 12 13

Select the discipline that shall be changed, e.g. Cooling Select system – CB1 Uncheck the checkbox if the systems object not shall be visible. Uncheck the checkbox if the systems object not shall be selectable Select system type - supply Select the current default dimension, e.g. 20. Select the size from where the system is shown only shown as a centre line. Select system colour. (Remark: 3D, colour templates controls the 2D colour) Select pipe serie. Select ”Update” Change system type to supply and set the colour. Select ”Update” Finish with OK.

The dialogue is split up in two parts. The upper is used to set the data for a certain discipline; the lower part is to set the current system data for that discipline. When colour is set to ”Not set” – the colour template sets the colour. Here you delete and rename systems, if there are pipes drawn in a system that is renamed – that system will remain together with the new system. This is also valid when systems are erased. The system comes back when CADvent restarts.

Start drawing with certain discipline

1. 2. 3. 4.

Select discipline to draw. Select H – height – at the command line. Enter height for centre line, 2400. Set start point for the pipe. If ”ortho” is activated before start – it will stay on – otherwise it‟s off from every new direction change.

CADvent selects the current system, size and colour for the selected discipline.

5. 6.

To change size, select S, and type the new size. CADvent selects the closest size available in the pipe series belonging to the system. If not the exact size can be selected the first larger is selected. To go to new height, select H and type in the new height.

Draw vertical:

Draw pipe route There are many ways to draw a pipe route depending on how

many pipes that shall be drawn and what height they shall reside on.

Alternative 1. A few pipes in the pipe route 1.

2. 3.

Draw 1 pipe, as far as possible, including height changes.

Use after that parallel pips to put out the other pipes in the route. Pick start- and end point of the pipe in the route that shall be copied.

4. 5. 6.

Select system and system type for the new pipe. Select OK Pick or type the distance – together with activated Ortho - between the pipes, select side to place the offset. Repeat step 3-6 until the pipe route is complete

Example The pipe is placed parallel with the original pipe at a distance of 200 mm. The elevation change in the route was also included in the parallel offset copy. The size of the pipes is set by the system data in the system setting dialogue.

Alternative 2: When several different pipes shall be included in the route and the position not is pre set.

1. 2.

Draw a small part of all the pipes that shall be included in the route. Select ‟Continue from‟

3. 4. 5. 6. 7.

Pick the end of the pipe that shall lead the route. Select M for (Multi) on the command line while having the ‟Continue‟-command is active. Select next pipe to be added in the route. Repeat step 3 and 4 until all the pipes are selected. Continue to draw the route with the active ‟Continue‟-command.

Remark! Only pipes at the same elevation can be included.

Tip!

Use the command ”copy and draw” to fast and easily draw new pipes in different systems and sizes than the ones in the system settings.
